Britain’s Boris Johnson to get AstraZeneca vaccine

Prime Minister Boris Johnson briefs on the Covid-19 coronavirus pandemic during a virtual press conference at 10 Downing Street on March 18, 2021 in London, England.

LONDON – UK Prime Minister Boris Johnson is expected to receive the first dose of the coronavirus vaccine developed by AstraZeneca and Oxford University on Friday to convince the public that the vaccine is safe and effective.

Johnson, 56, has urged other people to get vaccinated against Covid-19, citing data from the UK’s Independent Medicines Agency which suggests the benefits far outweigh the risks.

A number of countries around the world have suspended the use of the Oxford-AstraZeneca vaccine as a precautionary measure after blood clots were reported in some people who had been vaccinated. Health experts sharply criticized the move, citing a lack of data, while analysts expressed concerns about the impact on vaccine uptake as the virus continues to spread.

UK and EU regulators said there was no evidence that the vaccine caused blood clots. The World Health Organization also said the benefits of Oxford-AstraZeneca’s vaccine outweigh the risks and recommended vaccinations should continue.

Speaking at a conference on Downing Street Thursday, Johnson said the Oxford-AstraZeneca vaccine was safe, but “what isn’t safe is catching covid, which is why it’s so important that we all get our thrusts as soon as we can it’s our turn comes. “

The British leader himself was hospitalized for Covid in April and spent days in an intensive care unit.

French Prime Minister Jean Castex is expected to receive the Oxford-AstraZeneca vaccine on Friday.

Vaccine stocks

Germany, France, Italy and Spain are among the European countries that say they will use the vaccine again after the European Medicines Agency declares it safe and effective. Indonesia, which previously delayed administration of the Oxford-AstraZeneca vaccine, announced on Friday that it has approved its use.

However, Norway, Sweden and Denmark have announced that they will continue to stop using the vaccine while they conduct their own independent reviews.

The UK, which has not interrupted the launch of the Oxford-AstraZeneca shot, said delays in vaccine supplies next month would not affect England’s roadmap.

The National Health Service warned of a “significant reduction” in the weekly supply of Covid vaccines in England next month after fewer doses than originally expected had arrived from India.

Johnson said there was “no change” to the government’s plan to relax restrictive public health measures and insisted the roadmap was “on track” despite an unexpected drop in supply.

To date, more than 4.2 million people in the UK have contracted Covid with 126,163 deaths. This is based on data compiled by Johns Hopkins University.

LONDON – Two other countries decided on Tuesday to suspend use of the AstraZeneca vaccine in Europe amid blood clot concerns as regulators conducted a new side effects review.

Sweden and Latvia announced Tuesday morning that they are suspending the rollout of the AstraZeneca vaccine developed with Oxford University. Portugal, Luxembourg and Slovenia decided to stop using the shot on Monday evening. Earlier in the day, Germany, France, Italy and Spain also joined the group of nations that stopped using the vaccine.

So far, 13 countries in the European Union have made this decision, while a few others have stopped using individual lots of the AstraZeneca vaccine. Austria first decided last week after the death of a 49-year-old woman who received this vaccine to stop using a certain batch of AstraZeneca shots.

“The benefits still outweigh the risks.”

The European health authority has insisted that “the benefits of the AstraZeneca vaccine in preventing Covid-19, with the associated risk of hospitalization and death, outweigh the risks of side effects”.

In a statement on Monday, the European Medicines Agency said it would “look further into the information” and called an extraordinary meeting on Thursday on the subject. The institution then reiterated its position during a press conference on Tuesday.

“There is currently no evidence that vaccination caused these conditions,” said Emer Cooke, director of the European Medicines Agency. “The benefits still outweigh the risks, but this is a serious problem and requires serious and detailed scientific assessment. We are currently involved in that.”

She added, “We are concerned that this could affect vaccine confidence … but our job is to make sure the products we approve are safe.”

Of course, we need speed, not just for the economy, but above all for the health of our citizens, but at the same time we need security.

Paolo Gentiloni

EU commissioner for the economy

The World Health Organization has urged nations to continue their vaccination campaigns with the AstraZeneca vaccine and Oxford University.

A number of EU countries have spoken out in favor of the shot. In Belgium, Health Minister Frank Vandenbroucke said on Monday that interrupting use was “irresponsible”. While the authorities in the Czech Republic have also announced that they will continue to administer the vaccine.

Outside the EU, Canada, Australia and the UK have also joined forces to support AstraZeneca.

According to the European Center for Disease Prevention and Control, more than 6 million doses of the AstraZeneca shot have been administered in the EU to date.

AstraZeneca announced on Sunday that of the 17 million people vaccinated in the EU and the UK, 15 had deep vein thrombosis events and 22 cases of pulmonary embolism. This is based on data received as of March 8th.

“This is much less than expected to occur naturally in a general population of this size and it is similar to other approved Covid-19 vaccines,” the company said in a statement.

Concerns about the vaccine could jeopardize the EU’s goal of vaccinating 70% of the adult population by the end of the summer. The AstraZeneca vaccine has proven popular in Europe so far because it is cheaper than its competitors and easier to store. This could then possibly delay the economic recovery in the region.

“Of course we need speed, not only for the economy, but above all for the health of our citizens, but at the same time we need security,” said Paolo Gentiloni of the European Commission at a press conference on Monday.

He added that the precautionary measures were “justified” and that the EMA review should “keep our EU citizens safe”.

AstraZeneca vaccine halt might gradual Asia’s financial restoration: Moody’s Analytics

SINGAPORE – Asia’s economic recovery could slow as more countries stop using the Covid-19 vaccine developed by AstraZeneca and Oxford University, Moody’s Analytics chief Asia-Pacific economist warned.

“It slightly increases the risk Asia is playing in terms of global economic turnaround,” Steve Cochrane told CNBC’s “Squawk Box Asia” on Tuesday.

Reports of blood clots in some people who received the AstraZeneca Oxford shot resulted in several countries – many of them in Europe – temporarily stopping using the vaccine. The World Health Organization said there was no link between the shot and an increased risk of developing blood clots and is investigating this.

Impact of vaccines on world trade

Cochrane said issues related to the AstraZeneca-Oxford vaccine could affect world trade – and that’s bad news for Asia, where many economies are dependent on trading activities.

The vaccine is of course a risk. One of the critical risks is that vaccines will have to be introduced later this year to get the world economy back on its feet.

Steve Cochrane

Asia Pacific Chief Economist, Moody’s Analytics

“There is a possibility that world trade will be adversely affected if the introduction of vaccines in Europe is delayed. This would result in a more stalled economy in Europe. This could slow the pace of world trade.” ,” he explained.

Asian countries have contained the virus with relative success, and this has helped their economies recover faster than those in Europe and the US

Fortunately, re-locks in some parts of Europe haven’t affected manufacturing, Cochrane said. He added that “almost all” of the effects of these lockdowns have affected the service sector.

“So right now it’s not that big of a problem, and world trade still seems very, very strong,” said the economist. “The vaccine is, of course, a risk. It is one of the critical risks. We have yet to see how vaccines are introduced later this year to get the world economy back on its feet.”

Thailand briefly stops the AstraZeneca vaccine

Thailand temporarily stopped using the AstraZeneca-Oxford vaccine on Friday, but authorities said Monday they would continue to administer the shots.

Thai Prime Minister Prayuth Chan-ocha was the first in the country to receive the AstraZeneca-Oxford shot on Tuesday, Reuters reported.

Elsewhere in Asia, Indonesia on Monday said it would delay the rollout of the AstraZeneca-Oxford vaccine while awaiting review by the WHO, the news agency reported.

The AstraZeneca Vaccine: Ought to You Be Involved?

Millionen von Menschen in Dutzenden von Ländern haben den Impfstoff AstraZeneca Covid mit wenigen Berichten über Nebenwirkungen erhalten, und seine vorherigen Tests bei Zehntausenden von Menschen haben festgestellt, dass er sicher ist.

In jüngster Zeit haben Blutgerinnsel und abnormale Blutungen bei einer kleinen Anzahl von Impfstoffempfängern in europäischen Ländern Zweifel an ihrer Sicherheit aufkommen lassen, obwohl kein ursächlicher Zusammenhang zwischen dem Zustand der Patienten und dem Impfstoff festgestellt wurde. Die Berichte haben mehr als ein Dutzend Länder dazu veranlasst, die Verwendung des Impfstoffs während der Untersuchung der Fälle entweder teilweise oder vollständig auszusetzen. Die meisten Nationen gaben an, dies vorsorglich zu tun, bis führende Gesundheitsbehörden die Fälle überprüfen konnten.

Der AstraZeneca-Impfstoff wurde in den USA noch nicht zur Verwendung zugelassen, obwohl eine Überprüfung seiner US-Studie in Kürze erwartet wird.

Die Kaskade von Entscheidungen, die Verwendung des Impfstoffs von AstraZeneca vor allem durch europäische Länder zu unterbrechen, folgte Berichten über vier schwerwiegende Fälle in Norwegen, die unter Gesundheitspersonal unter 50 Jahren beschrieben wurden, die den Impfstoff erhielten. Die meisten entwickelten Gerinnsel oder Blutungsstörungen und hatten niedrige Thrombozytenzahlen, sagten die Gesundheitsbehörden dort. Zwei von ihnen sind an Gehirnblutungen gestorben, die anderen beiden werden ins Krankenhaus eingeliefert. Der Tod einer 60-jährigen Frau in Dänemark und eines 57-jährigen Mannes in Italien führte ebenfalls zu schnellen Entscheidungen, obwohl keiner der Todesfälle vollständig untersucht wurde, um festzustellen, ob ein Zusammenhang mit den erhaltenen Schüssen besteht.

Ein Blutgerinnsel ist ein verdickter, gallertartiger Blutklumpen, der die Durchblutung blockieren kann. Gerinnsel bilden sich als Reaktion auf Verletzungen und können auch durch viele Krankheiten verursacht werden, einschließlich Krebs und genetischen Störungen, bestimmten Medikamenten und längerem Sitzen oder Bettruhe. Gerinnsel, die sich in den Beinen bilden, brechen manchmal ab und wandern in die Lunge oder ins Gehirn, wo sie tödlich sein können.

Es wurde nicht nachgewiesen, dass Impfstoffe Blutgerinnsel verursachen, sagte Daniel Salmon, Direktor des Instituts für Impfsicherheit an der Johns Hopkins University.

Blutgerinnsel sind in der Allgemeinbevölkerung häufig, und die Gesundheitsbehörden vermuten, dass die bei Impfstoffempfängern gemeldeten Fälle höchstwahrscheinlich zufällig sind und nicht mit der Impfung zusammenhängen.

“Es gibt viele Ursachen für die Blutgerinnung, viele prädisponierende Faktoren und viele Menschen mit erhöhtem Risiko – und dies sind oft auch die Menschen, die gerade geimpft werden”, sagte Mark Slifka, ein Impfstoffforscher an der Oregon Health and Science University.

Laut den Centers for Disease Control and Prevention entwickeln in den USA 300.000 bis 600.000 Menschen pro Jahr Blutgerinnsel in ihrer Lunge oder in Venen in den Beinen oder anderen Körperteilen.

Laut diesen Daten treten in der US-Bevölkerung täglich etwa 1.000 bis 2.000 Blutgerinnsel auf, so Dr. Stephan Moll, Hämatologe und Professor für Medizin an der University of North Carolina.

“Die Vereinigten Staaten haben 253 Millionen Erwachsene”, sagte Dr. Moll. “Wenn also jeden Tag 2,3 Millionen Menschen in den USA mit Covid geimpft werden, bedeutet dies, dass täglich etwa 1 Prozent der erwachsenen Bevölkerung geimpft wird.”

Weiter berechnet, sagte er, würde ungefähr 1 Prozent der 1.000 bis 2.000 täglichen Blutgerinnsel – 10 bis 20 pro Tag – bei den geimpften Patienten nur als Teil der normalen Hintergrundraten auftreten, die nicht mit dem Impfstoff zusammenhängen.

“Nur wenn epidemiologische Daten zeigen, dass diese Rate höher ist, würde man sich über einen ursächlichen Zusammenhang wundern”, sagte Dr. Moll.

Dr. David Wohl, Direktor der Impfklinik an der Universität von North Carolina, sagte, er habe in den großen klinischen Studien, die zu ihrer Zulassung führten, keine Beweise dafür gesehen, dass einer der Covid-Impfstoffe Blutgerinnsel, auch Thrombose genannt, verursacht habe.

Dr. Wohl bemerkte aber auch: “Es gibt Unterschiede zwischen Prüfungen und dem wirklichen Leben.”

Die umfangreichsten Sicherheitsergebnisse aus der realen Einführung des Impfstoffs von AstraZeneca stammen aus Großbritannien, wo im letzten Monat 9,7 Millionen Dosen des Impfstoffs verabreicht wurden. Die britischen Daten ergaben, dass zumindest einige Gerinnungszustände, obwohl sie äußerst selten sind, bei Personen, die mit dem Impfstoff von AstraZeneca geimpft wurden, im Vergleich zu Personen, die Pfizers Produkt erhielten, gleich häufig waren. Aber ungewöhnlich niedrige Thrombozytenwerte waren bei Menschen, die den Impfstoff gegen AstraZeneca erhielten, häufiger.

Außerhalb von Studien werden die Impfstoffe einem breiteren Personenkreis verabreicht. Wenn also Sicherheitsfragen auftauchen, sobald ein Impfstoff allgemeiner angewendet wird, sollten die Fragen untersucht werden, sagte Dr. Wohl.

15. März 2021, 22:30 Uhr ET

“Wir wollen ein Signal nicht ignorieren, das auf ein größeres Problem hinweisen könnte”, sagte er. “Aber zu diesem Zeitpunkt ist es verfrüht zu glauben, dass AstraZeneca Thrombosen verursacht.”

Andere Impfstoffe, insbesondere solche, die Kindern gegen Masern, Mumps und Röteln verabreicht wurden, wurden mit vorübergehend verringerten Blutplättchenspiegeln in Verbindung gebracht, einer für die Gerinnung essentiellen Blutkomponente.

Bei einer kleinen Anzahl von Patienten, die die Impfstoffe Moderna, Pfizer-BioNTech und AstraZeneca erhielten, wurde über verringerte Thrombozytenwerte berichtet. Ein Empfänger, ein Arzt in Florida, starb an einer Gehirnblutung, als seine Thrombozytenwerte nicht wiederhergestellt werden konnten, und andere wurden ins Krankenhaus eingeliefert. US-Gesundheitsbehörden haben erklärt, dass die Fälle untersucht werden, sie haben jedoch die Ergebnisse dieser Überprüfungen nicht gemeldet und müssen noch darauf hinweisen, dass ein Zusammenhang mit den Impfstoffen besteht.

Die Europäische Arzneimittel-Agentur gab am Montag bekannt, dass sie mit AstraZeneca und den Gesundheitsbehörden zusammenarbeitet, um “alle verfügbaren Daten und klinischen Umstände in Bezug auf bestimmte Fälle” zu prüfen.

Die Behörden haben nicht detailliert angegeben, wie diese Bewertung aussehen wird. Bei der Beurteilung eines möglichen Zusammenhangs zwischen einem Impfstoff und einer schwerwiegenden Nebenwirkung konzentrieren sich die Ermittler im Allgemeinen darauf, abzuschätzen, wie oft solche medizinischen Probleme in der betreffenden Personengruppe zufällig auftreten dürften.

Das könnte bedeuten, dass man sich Leute in derselben Gruppe ansieht, bevor sie geimpft wurden. Es könnte auch bedeuten, eine ähnliche Gruppe von Menschen zu betrachten. Wenn die Rate dieser Probleme in der geimpften Gruppe höher ist als in einer vergleichbaren Population zu erwarten, ist dies ein Zeichen dafür, dass das Sicherheitsproblem real ist oder zumindest eine genauere Prüfung wert ist.

Solche Untersuchungen hängen typischerweise nicht davon ab, endgültig herauszufinden, ob der Impfstoff die Todesursache oder ein ernstes medizinisches Problem war, da dies in den meisten Fällen nicht endgültig bestimmt werden kann. Die Ermittler berücksichtigen jedoch die Anamnese, z. B. ob eine Person vor der Impfung wegen ähnlicher medizinischer Probleme behandelt wurde.

Die Ermittler berücksichtigen auch Faktoren, die die Wahrscheinlichkeit erhöhen, dass eine Gruppe von Menschen krank wird. Ältere Menschen, die in Impfkampagnen auf der ganzen Welt Vorrang haben, haben ein höheres Risiko, Blutgerinnsel zu entwickeln als jüngere.

Was Sie über den Impfstoff-Rollout wissen müssen

Einzelne Gesundheitsministerien führen ebenfalls Untersuchungen durch, und die Gesundheitsbehörden in diesen Ländern warten auf die Ergebnisse der Autopsien. In Italien haben die Behörden außerdem im Rahmen einer Untersuchung des Todes des Lehrers am Wochenende Dosen des Impfstoffs in der Region Piemont beschlagnahmt.

Ein Beratungsausschuss der Weltgesundheitsorganisation plant, sich am Dienstag zu treffen, um den Impfstoff zu erörtern. Der Sicherheitsausschuss der Europäischen Arzneimittel-Agentur wird am Donnerstag zusammentreten.

Jennifer Nuzzo, Epidemiologin am Center for Health Security der Johns Hopkins University, hoffte, dass die Behörden regelmäßig über den Stand der Untersuchung der Sicherheit des AstraZeneca-Impfstoffs informieren würden – was bei Sicherheitsproblemen häufig nicht der Fall ist geprüft.

“Ich wünschte wirklich, es könnte mehr Kommunikation darüber geben, welche Arten von Analysen sie durchführen, was sie betrachten, auch wenn sie vorübergehend sind – nur um Transparenz in den Prozess zu geben, um das Vertrauen in den Prozess zu verbessern”, sagte Dr. Sagte Nuzzo.

AstraZeneca hat sich vor einer Woche erstmals öffentlich mit den Sicherheitsbedenken befasst, nachdem Österreich die Impfungen gegen eine Charge des Impfstoffs von AstraZeneca eingestellt hatte. Ein Unternehmenssprecher sagte damals, dass keine schwerwiegenden Nebenwirkungen des Impfstoffs bestätigt worden seien.

Am Donnerstag, nachdem Dänemark alle Impfungen mit dem Produkt von AstraZeneca eingestellt hatte, gab das Unternehmen eine Erklärung ab, in der es die Sicherheit seines Impfstoffs deutlicher verteidigte. Die Sicherheitsdaten von AstraZeneca, eine Fundgrube von mehr als 10 Millionen Datensätzen, zeigten keine Hinweise auf ein erhöhtes Risiko für Blutgerinnselprobleme in einer demografischen Gruppe oder einem Land, so das Unternehmen.

Nachdem mehrere weitere Länder Pläne angekündigt hatten, ihre Impfkampagnen auszusetzen, veröffentlichte AstraZeneca am Sonntag eine Pressemitteilung mit genaueren Angaben zur Anzahl der gemeldeten Nebenwirkungen und zu Personen, die in klinischen Studien und Impfkampagnen in Europa geimpft wurden.

Am Montag sagte ein Sprecher von AstraZeneca, das Unternehmen arbeite “mit nationalen Gesundheitsbehörden und europäischen Beamten zusammen und freue sich auf deren Bewertung im Laufe dieser Woche”. (Das Unternehmen weigerte sich, den Sprecher zu benennen.)

Bedenken hinsichtlich der Sicherheit von Impfstoffen in der Vergangenheit wurden in der Regel nicht durch die Beweise bestätigt, obwohl es Ausnahmen gibt. 1999 wurde der erste Impfstoff gegen die Rotavirus-Infektion, die bei Säuglingen Durchfall verursacht, vom Markt genommen, da festgestellt wurde, dass er das Risiko einer Darmobstruktion erhöht.

Aber selbst unbegründete Sicherheitsbedenken haben das Vertrauen der Öffentlichkeit geschwächt.

Nachdem die Food and Drug Administration 1998 einen hochwirksamen Impfstoff gegen Lyme-Borreliose zugelassen hatte, haben Medienberichte und eine Sammelklage Beschwerden von Personen angeheizt, die angaben, nach der Impfung Arthritis entwickelt zu haben. Im Jahr 2001 berief die FDA eine Expertengruppe ein, um die Sicherheitsdaten des Impfstoffs zu überprüfen – klinische Studien hatten keinen Unterschied in der Häufigkeit langfristiger Gelenksymptome zwischen der Impfstoff- und der Placebo-Gruppe ergeben – und kam zu dem Schluss, dass der Impfstoff auf dem Markt bleiben sollte .

Bis dahin war die öffentliche Wahrnehmung des Impfstoffs jedoch zu weit gegangen: Ein starker Umsatzrückgang spornte den Impfstoffhersteller GlaxoSmithKline an, den Impfstoff 2002 vom Markt zu nehmen.

Während mehr als 70 Länder den Impfstoff zugelassen haben, haben die Vereinigten Staaten dies nicht getan. AstraZeneca hat noch keine Genehmigung bei der Food and Drug Administration beantragt und wartet auf die Ergebnisse seiner US-Studie, an der mehr als 32.000 Teilnehmer teilnahmen.

Eine Ankündigung von AstraZeneca zu diesen Ergebnissen könnte in Kürze erfolgen: Die Daten aus dieser Studie werden derzeit von einem unabhängigen Expertengremium geprüft, sagte Dr. Francis Collins, der Direktor der National Institutes of Health, am Montag gegenüber Reuters.

Laut Geoffrey Porges, Analyst bei der Investmentbank SVB Leerink, könnten die Ergebnisse dieser Studie die Sicherheit und Wirksamkeit dieser Studie erheblich verbessern, um die Menschen über den Impfstoff von AstraZeneca zu beruhigen.

“Aber je länger dies da draußen bleibt, ohne eine umfassende Überprüfung und ohne die Ergebnisse der US-Phase 3, desto mehr Menschen werden besorgt sein”, sagte Porges.

Eire, Netherlands droop AstraZeneca vaccine amid blood clot fears

LONDON – Ireland and the Netherlands have joined the growing list of countries that have stopped using the coronavirus vaccine developed by AstraZeneca and Oxford University because of blood clot concerns.

The Dutch government said Sunday that the Oxford-AstraZeneca vaccine would not be used until March 29, while Ireland said earlier in the day it had temporarily suspended the shot as a precautionary measure.

The World Health Organization tried to downplay the ongoing safety concerns and stated last week that there was no link between the shot and an increased risk of developing blood clots. The United Nations Health Department has urged countries to continue using the Oxford-AstraZeneca vaccine.

Even so, some European countries have already stopped using the Oxford-AstraZeneca vaccine. It added to the worries of the battered vaccination campaign in the region when the German health department warned that a third wave of coronavirus infections had already begun.

Thailand has also stopped the planned use of the vaccine.

The move to suspend use by Dutch and Irish officials came shortly after the Norwegian Medicines Agency announced that three health workers were hospitalized for bleeding, blood clots and low platelet counts after receiving the Oxford-AstraZeneca vaccine. Norway has suspended its vaccination program against Oxford-AstraZeneca.

Geir Bukholm, director of the Infection Control and Environmental Health Department at the Norwegian Public Health Institute, said the Norwegian Medicines Agency will “follow up on these suspected side effects and take the necessary action in this serious situation”.

The European Medicines Agency, the European Medicines Agency, also said there is no evidence that Oxford-AstraZeneca’s vaccine causes blood clots and that the vaccine’s benefits “continue to outweigh the risks”.

The EMA admitted that some European countries had stopped using the Oxford-AstraZeneca shot, but said vaccinations may continue to be given while a clot investigation is ongoing.

How did AstraZeneca react?

“A careful review of all available safety data from more than 17 million people vaccinated with the AstraZeneca COVID-19 vaccine in the European Union (EU) and the UK found no evidence of an increased risk of pulmonary embolism, deep vein thrombosis ( DVT) or thrombocytopenia in a certain age group, gender, group or country, “AstraZeneca said in a statement on Sunday.

The most common side effects of the Oxford AstraZeneca vaccine, which does not contain the virus and cannot cause Covid, are usually mild or moderate and improve within a few days after vaccination.

A health worker holds a box of the AstraZeneneca vaccine at the Bamrasnaradura Institute for Infectious Diseases in Nonthaburi Province on the outskirts of Bangkok.

The pharmaceutical company said that 15 events involving deep vein thrombosis and 22 events involving pulmonary embolism were reported among those vaccinated in the EU and the United Kingdom.

“This is much less than expected to occur naturally in a general population of this size, and it is similar to other approved COVID-19 vaccines,” said AstraZeneca.

What do the experts say?

“Covid definitely causes bleeding disorders and each of the vaccines prevents Covid disease, including more severe cases,” said Stephen Evans, professor of pharmacoepidemiology at the London School of Hygiene & Tropical Medicine.

“Therefore, it is highly likely that the vaccine’s benefits will significantly outweigh the risk of clotting disorders, and the vaccine will prevent other consequences of Covid, including deaths from other causes.”

Evans said it was “perfectly reasonable” to conduct studies on vaccines and coagulation disorders, but added, “It seems a step too far to take precautionary measures that would prevent people from receiving vaccines that prevent disease.”

Many high-income countries – such as the UK, France, Australia and Canada – have decided to continue rolling out the Oxford-AstraZeneca vaccine.

“When there is clear evidence of serious or life-threatening side effects that have important consequences,” Adam Finn, professor of pediatrics at Bristol University, said in a statement.

“So far, however, this has not been the case, and it is highly undesirable to disrupt a complex and urgent program every time people, after receiving a vaccine, develop illnesses that are random and not causal. In situations like this, it is not easy to Making the right call, but a steady hand on the tiller is probably what is needed most, “said Finn.

EU says AstraZeneca not doing sufficient to satisfy vaccine supply goal

LONDON – The European Union has asked AstraZeneca to do more to meet its contract with the bloc as concerns grow that the pharmaceutical company will again miss delivery targets.

It is not the first time that the EU and the drug giant have been at odds with each other. AstraZeneca initially offered to sell around 100 million Doses of his Covid-19 burst before the end of March. However, the company had to renegotiate that amount to just 40 million due to manufacturing issues.

The European Commission, the body that negotiates vaccination contracts on behalf of the 27 member states, is now concerned that this reduced amount will not be respected either.

“AstraZeneca vaccine supply: I see efforts but not ‘best efforts’. This is not yet good enough for AstraZeneca to meet its Q1 commitments,” said Thierry Breton, Internal Market Officer, Thursday evening on Twitter .

Data from the European Center for Disease Prevention and Control shows that 11.76 million doses of the AstraZeneca vaccine had been delivered as of Thursday.

“It is time for AstraZeneca’s board of directors to take on their fiduciary responsibility and do everything possible now to meet AZ’s commitments,” said Breton.

AstraZeneca wasn’t immediately available for comment when CNBC reached out on Friday.

The firm’s CEO, Pascal Soriot, told European lawmakers last month that the reason for the delays was the low return on EU plants. He also said his company was working around the clock to increase production and that it only had six months to prepare the sting, compared to other previous work that took years to develop a new vaccine.

EU “a watchful eye”

At a press conference last month, the President of the European Commission, Ursula von der Leyen, said the EU was “closely monitoring” AstraZeneca’s deliveries.

The supply problem has caused Italy to stop shipping AstraZeneca vaccines destined for Australia last week.

European countries can ban the export of Covid-19 vaccines if a pharmaceutical company fails to perform its contract and the vaccines are supposed to go to a country that is not classified as vulnerable. Low- and middle-income countries and neighboring countries are exempt from these restrictions.

Realizing that there may be further problems with AstraZeneca’s deliveries could lead Member States to stop further deliveries of this vaccine.

The introduction of vaccination is fundamental to the region’s economic recovery, and new problems with bumps could ruin the exit from the crisis.

European Central Bank President Christine Lagarde said on Thursday: “The ongoing vaccination campaigns and the gradual easing of containment measures – apart from other adverse developments related to the pandemic – support expectations of a significant recovery in economic activity over the course of 2021.” “

The EU vaccination program has so far been criticized several times. Some countries have complained that regulators are too slow to approve the bumps compared to other parts of the world. There were production and delivery problems. Bureaucracy at the national level has also hampered the process.

The EU has committed to vaccinating 70% of the adult population before the end of summer.

Earlier this week, the commission agreed with Pfizer and BioNTech to receive 4 million additional doses of their vaccine over the next two weeks.

On Thursday, the block also approved its fourth Covid-19 vaccine with the Johnson & Johnson candidate.

AstraZeneca Covid vaccine suspended in some international locations over blood clot fears

LONDON – The coronavirus vaccine developed by AstraZeneca and Oxford University has been exposed in a number of countries in Europe and Asia after reports of blood clots in some vaccinated people.

However, many other nations have defended their use of the shot and announced that they will continue their respective vaccination campaigns.

Thailand became the first Asian country to stop using the sting on Friday due to safety concerns, shortly after Denmark announced a two-week hiatus from its nationwide rollout after reports of blood clots and a death.

In a setback to the battered vaccination campaign in Europe, seven other countries have also suspended the use of the Oxford-AstraZeneca shot: Norway, Iceland, Bulgaria, Luxembourg, Estonia, Lithuania and Latvia.

Austria and Italy have since announced that they will no longer use certain batches of the vaccine as a precaution.

The European Medicines Agency, the European Medicines Agency, stressed Thursday that there was no evidence that the shot was causing blood clots, adding that the vaccine’s benefits “continue to outweigh the risks”.

The EMA acknowledged that some member states had stopped using the Oxford-AstraZeneca shot, but said vaccinations may continue to be given while a clot investigation is ongoing.

By Wednesday, around 5 million people in Europe had received the Oxford-AstraZeneca vaccine. Of this number, 30 cases of so-called “thromboembolic events” were reported. These cases relate to blood clots that form in the blood vessels and block blood flow.

AstraZeneca said the vaccine has been extensively studied in Phase 3 trials and peer-reviewed data confirms the shot is “generally well tolerated.”

Why do countries pause vaccination campaigns?

The Thai Ministry of Health announced on Friday that it would temporarily postpone the use of the Oxford-AstraZeneca vaccine. The shot is reportedly labeled a “good vaccine” but is said to be suspended for safety investigation.

Kiattiphum Wongjit, permanent secretary of the health ministry, said the Southeast Asian country may suspend its vaccination campaign as it has largely controlled a second wave of Covid cases through quarantines and border controls, according to Reuters.

A press conference will be held on March 12, 2021 in Bangkok, Thailand, to temporarily suspend the introduction of vaccination against AstraZeneca Covid-19 in Thailand.

The country of nearly 70 million people has so far recorded around 26,600 cases and 85 deaths, according to Johns Hopkins University.

The decision of Thailand to suspend the planned launch of the Oxford-AstraZeneca vaccine, which was due to start on Friday, was made following the decision of the Danish health authority.

“It is important to emphasize that we have not decided against the AstraZeneca vaccine, but are putting it on hold,” said Soren Brostrom, director of the National Health Agency in Denmark, on Thursday.

“There is good evidence that the vaccine is both safe and effective. However, we and the Danish Medicines Agency need to respond to reports of possible serious side effects from both Denmark and other European countries.”

Many high-income countries have chosen to continue rolling out the Oxford-AstraZeneca vaccine for safety reasons.

The UK, France, Australia, Canada and Mexico are among the nations that have tried to reassure citizens about the vaccine’s benefits and have announced that they will continue their respective vaccination campaigns.

“An analysis of our safety data of more than 10 million records has shown no evidence of an increased risk of pulmonary embolism or deep vein thrombosis in any particular age group, gender, batch or country with AstraZeneca COVID-19 vaccine.” said an AstraZeneca spokesman.

“In fact, the number of these types of events observed is significantly lower in vaccinated people than would be expected in the general population.”

What do the experts say?

The EMA’s safety committee is investigating the problem, but has determined that there is currently no evidence that the vaccination caused blood clots. It should be noted that these are not listed as side effects of this vaccine.

The European Medicines Agency also noted that the data available so far showed that the number of blood clots in vaccinated people is no higher than in the general population.

“Reports of previously received blood clots are no greater than the numbers that would have occurred naturally in the vaccinated population,” said Dr. Phil Bryan, Vaccine Safety Director for the UK Medicines and Health Products Agency.

“Public safety will always come first. We will continue to examine this issue carefully, but the evidence available does not confirm the vaccine is the cause. People should still get their COVID-19 vaccine when prompted become.” Said Bryan.

Peter Brownsea, a Southampton resident, receives the Oxford / AstraZeneca Covid-19 vaccine from a member of the Hampshire Fire and Rescue Service at a temporary vaccination center at the Basingstoke Fire Station in Hampshire, southern England, while crews continue to answer 999 emergency calls.

Stephen Evans, Professor of Pharmacoepidemiology at the London School of Hygiene & Tropical Medicine, said: “The problem with spontaneous reports of suspected vaccine side effects is the tremendous difficulty in distinguishing a causal effect from a coincidence.”

“This is especially true when we know that Covid-19 disease is very closely related to blood clotting and that there have been hundreds, if not many thousands of deaths caused by blood clotting as a result of Covid-19 disease. That first thing to do is to be absolutely sure that the clots were not caused by any other cause, including Covid-19, “added Evans.

How does the vaccine work?

The Oxford AstraZeneca vaccine is designed to prevent coronavirus in people aged 18 and over. It’s made up of an adenovirus that has been modified to contain the gene to make a protein from SARS-CoV-2, the virus that causes Covid-19.

The most common side effects of the shot, which does not contain the virus and cannot cause Covid, are typically mild or moderate and improve within a few days after vaccination.

In late clinical studies, the AstraZeneca-Oxford shot was found to have an average of 70% effectiveness in protecting against the virus.

A recent study by Oxford researchers found that the Covid vaccine was 76% effective at preventing symptomatic infection for three months after a single dose and that the effectiveness rate actually increased with a longer interval between the first and second dose.

European Nations Droop Use of AstraZeneca Photographs Over Worries About Blood Clots

Italy’s suspension of another batch was tied to a man in Sicily who died after receiving his shot. It is unclear whether a blood clot was involved.

The vaccine manufactured by AstraZeneca has been injected into more than 142,000 people in Denmark, which has a population of around six million.

The Danish Health Minister Magnus Heunicke said on Twitter that it was “currently not possible to determine whether there is a connection”. He added: “We acted early, it needs a thorough investigation.”

Denmark had already cut the target for the completion of its vaccination campaign, partly due to delivery delays. The safety break will delay it further.

AstraZeneca’s vaccine was screened for potential safety issues over the past year while being tested in clinical trials. Two vaccinated volunteers in the UK developed neurological symptoms related to transverse myelitis, an inflammatory syndrome that affects the spinal cord and is often caused by viral infections.

These concerns temporarily put the vaccine to a halt around the world, but the investigation ultimately found no evidence to link the symptoms to the vaccine. One of the sick participants was later found to have an undiagnosed case of multiple sclerosis.

Since then, more than 70 countries have approved the vaccine, with the exception of the United States, where regulators are waiting for data from a large clinical trial expected in the next few weeks. A Food and Drug Administration decision to approve AstraZeneca’s vaccine is likely more than a month away.

The largest real world data on the safety of the vaccine comes from the UK, which had given 9.7 million doses in the last month. The UK Medicines Agency, the regulator of medicines and health products, said: “The number and types of suspected adverse reactions reported to date are not uncommon when compared to other types of vaccines routinely used.”

Denmark suspends use of AstraZeneca Covid vaccine

LONDON – Denmark announced on Thursday that it would temporarily stop using the coronavirus vaccine developed by AstraZeneca and Oxford University.

The Danish health authority said it would temporarily suspend the use of the shot in its vaccination program “following reports of severe cases of blood clots in people vaccinated with AstraZeneca’s COVID-19 vaccine”.

“With this in mind, the European Medicines Agency has launched an investigation into the AstraZeneca vaccine. One report relates to a death in Denmark. It cannot currently be concluded whether the vaccine is related to the blood clots.” Authority said in a statement.

No information was provided about the number of reports of blood clots or where they came from.

The announcement comes after a similar move in Austria earlier this week, where authorities are investigating one person’s death and another person’s illness after receiving doses of the vaccine.

AstraZeneca’s shares in the London market were down 2.4% on Thursday morning. Oxford University would not comment on the announcement when contacted by CNBC.

An AstraZeneca spokesman said the company was aware of a statement by the Danish health authority that it is investigating possible adverse effects of the vaccine.

“Patient safety is a top priority for AstraZeneca. Regulators have clear and strict standards of efficacy and safety for approving new drugs, including the COVID-19 vaccine AstraZeneca. The vaccine’s safety has been thoroughly investigated in Phase III clinical trials. Review data confirms the vaccine is generally well tolerated, “AstraZeneca said in a statement to CNBC.

Søren Brostrøm, director of the National Health Department in Denmark, insisted that the 14-day suspension was a precautionary measure during the investigation.

“It is important to emphasize that we did not decide against the AstraZeneca vaccine, we are deferring it. There is good evidence that the vaccine is both safe and effective. But both we and the Danish Medicines Agency need to respond Reports of possible serious side effects from both Denmark and other European countries, “he said.

Austria concerns

The Austrian health authorities stopped using batch ABV5300 of the AstraZeneca vaccine after a person was diagnosed with multiple thrombosis (formation of blood clots in blood vessels) and died 10 days after vaccination. Another person was hospitalized with pulmonary embolism after vaccination.

“The latter is now recovering,” said the European Medicines Agency on Wednesday.

However, the EMA added that “there is currently no evidence that vaccination caused these conditions that are not listed as side effects with this vaccine.”

The EMA found that the same batch of ABV5300 was shipped to 17 EU countries and comprised 1 million doses of the vaccine.

“Some EU countries have also suspended this batch as a precautionary measure while a full investigation is in progress. Although a quality defect is considered unlikely at this point, the batch quality will be investigated,” said the EMA.

It added that its safety committee was reviewing the issue and “investigated the cases reported with the batch, as well as all other cases of thromboembolic events and other blood clot-related conditions post-vaccination.”

“The information available so far shows that the number of thromboembolic events in vaccinated people is no higher than in the general population.”

As of March 9, “22 cases of thromboembolic events have been reported among the 3 million people vaccinated with the AstraZeneca COVID-19 vaccine in the European Economic Area,” the EMA said.

Trust in the UK and the EU

In late clinical studies, the AstraZeneca-Oxford shot was found to have an average of 70% effectiveness in protecting against the virus. A recent study by Oxford researchers found that the Covid vaccine was 76% effective at preventing symptomatic infection for three months after a single dose and that the effectiveness rate actually increased with a longer interval between the first and second dose.

The AstraZeneca-Oxford vaccine is widely used in the launch of vaccination in the UK and the European Union.

The UK has so far vaccinated over 22 million people with a first dose of a coronavirus vaccine and is currently only using the AstraZeneca and Pfizer-BioNTech shot.

Italy blocks shipments of AstraZeneca Covid vaccine

LONDON – The European Union intervened in the supply of coronavirus vaccines for the first time. Italy reportedly blocked delivery of the AstraZeneca-Oxford vaccine to Australia on Thursday.

Reuters, citing two sources, reported that the British pharmaceutical company AstraZeneca had asked Rome for permission to ship around 250,000 doses from its plant in Anagni, Italy. However, the Italian government refused. The Financial Times also reported the same story.

An AstraZeneca spokesman declined to comment when contacted by CNBC. A spokesman for the EU or the Italian Foreign Ministry was not immediately available to comment.

In January, the European Union temporarily controlled exports of vaccines made within the bloc after AstraZeneca and other supply problems were spat at. The EU has been under pressure from what critics are calling the slow adoption of Covid vaccines.

The European Commission, the body that runs the sales contracts, has been accused of not securing enough vaccines and the region’s medical agency has been criticized for taking too long to approve vaccinations that have given the go-ahead elsewhere have received.

The controls will last until the end of March and give EU member states the power to refuse to authorize exports if vaccine manufacturers fail to comply with contracts.

In January, AstraZeneca announced that it would deliver far fewer cans to the EU than originally expected in the spring due to production problems at its plants in the Netherlands and Belgium. Then on January 31, it announced it would dispose of an additional 9 million doses in the first quarter to make up for the deficit.
