Can the Vaccinated Develop Lengthy Covid After a Breakthrough An infection?

Can the Vaccinated Develop Long Covid After a Breakthrough Infection?

While some breakthrough cases in people fully vaccinated against Covid-19 are inevitable, they are unlikely to result in hospitalization or death. But an important question about breakthrough infection remains unanswered: Can the vaccinated develop a so-called long covid?

Long Covid refers to a range of symptoms – such as severe fatigue, brain fog, headache, muscle aches, and trouble sleeping – that can last for weeks or months after the active infection has ended. The syndrome is little known, but studies suggest that between 10 and 30 percent of adults who contract the virus can have Covid for a long time, including those who had mild illness or no symptoms at all.

But the vast majority of the long-term data collected by Covid concerns the unvaccinated population. The risk of developing long-term Covid has not been studied in fully vaccinated people who become infected after vaccination.

While preliminary research suggests that it is indeed possible that a breakthrough case could lead to symptoms that could last weeks to months, there are still more questions than answers. What percentage of breakthrough cases result in persistent symptoms? How many of these people are recovering? Are the persistent symptoms after a breakthrough infection as severe as with the unvaccinated?

“I just don’t think there’s enough data,” said Dr. Zijian Chen, medical director of the Center for Post-Covid Care at Mount Sinai Health System in New York. “It’s too early to say that. The number of people who get sick after vaccination is not that high right now, and there is no good tracking mechanism for these patients. “

A study of Israeli health workers recently published in the New England Journal of Medicine offers insight into the risk of long-term Covid infection after a breakthrough infection. Of 1,497 fully vaccinated health care workers, 39 – approximately 2.6 percent – developed breakthrough infections. (All workers were thought to be infected after contact with an unvaccinated person, and the study was conducted before the delta variant became dominant.)

While most breakthrough cases were mild or asymptomatic, seven out of 36 workers observed after six weeks (19 percent) still had persistent symptoms. These long Covid symptoms included a mixture of persistent loss of smell, persistent cough, fatigue, weakness, shortness of breath, or muscle pain.

However, the study’s authors caution against drawing too many conclusions from the research. The sample size – only seven patients – is small. And the research is designed to look at antibody levels in those infected, said Dr. Gili Regev-Yochay, Director of the Department of Epidemiology of Infectious Diseases at Sheba Medical Center. It was not designed to study the risk of long-term Covid illness after a breakthrough infection.

“That was not the scope of this paper,” said Dr. Regev-Yochay. “I don’t think we have an answer to that.”

Still, the fact that one in five healthcare workers who had a breakthrough infection still had persistent symptoms after six weeks seems to be the first clue from a peer-reviewed study that long Covid is possible after a breakthrough infection.

“People said to me, ‘You are fully vaccinated. Why are you so careful? ‘”Said Dr. Robert M. Wachter, professor and chair of the medical school at the University of California at San Francisco. “I’m still in the camp that I don’t want to get Covid. I don’t want to get a breakthrough infection. “

Dr. Wachter said that despite the many limitations of the Israeli study, the data provides more evidence that those vaccinated should continue to take reasonable precautions to avoid the virus.

“I’ll take it at face value that one in five people continued to feel bad six weeks after a breakthrough,” said Dr. Guardian. “That’s enough to wear two masks when you go shopping in the supermarket, which isn’t that stressful anyway.”

Understand the state of vaccination and masking requirements in the United States

    • Mask rules. The Centers for Disease Control and Prevention in July recommended that all Americans, regardless of vaccination status, wear masks in public places indoors in areas with outbreaks, reversing the guidelines offered in May. See where the CDC guidelines would apply and where states have implemented their own mask guidelines. The battle over masks is controversial in some states, with some local leaders defying state bans.
    • Vaccination regulations. . . and B.Factories. Private companies are increasingly demanding coronavirus vaccines for employees with different approaches. Such mandates are legally permissible and have been confirmed in legal challenges.
    • College and Universities. More than 400 colleges and universities require a vaccination against Covid-19. Almost all of them are in states that voted for President Biden.
    • schools. On August 11, California announced that teachers and staff at both public and private schools would have to get vaccinated or have regular tests, the first state in the nation to do so. A survey published in August found that many American parents of school-age children are against mandatory vaccines for students but are more likely to support masking requirements for students, teachers and staff who are not vaccinated.
    • Hospitals and medical centers. Many hospitals and large health systems require their employees to have a Covid-19 vaccine, due to rising case numbers due to the Delta variant and persistently low vaccination rates in their communities, even within their workforce.
    • new York. On August 3, New York City Mayor Bill de Blasio announced that workers and customers would be required to provide proof of vaccination when dining indoors, gyms, performances, and other indoor situations. City hospital staff must also be vaccinated or have weekly tests. Similar rules apply to employees in New York State.
    • At the federal level. The Pentagon announced that it would make coronavirus vaccinations compulsory for the country’s 1.3 million active soldiers “by mid-September at the latest. President Biden announced that all civil federal employees would need to be vaccinated against the coronavirus or undergo regular tests, social distancing, mask requirements and travel restrictions.

Making breakthrough infection research difficult is the fact that the U.S. Centers for Disease Control and Prevention only track post-vaccination infections that result in hospitalization or death. While the CDC continues to study breakthrough infections in several large cohorts, the lack of data on all breakthrough cases remains a source of frustration among scientists and patient organizations.

“It is very frustrating not to have data at this point in the pandemic to know what will happen to breakthrough cases,” said Akiko Iwasaki, an immunologist at Yale School of Medicine who conducts studies on long-term Covid. “When a mild breakthrough infection turns into a long Covid, we don’t have that number under control.”

Diana Berrent, founder of Survivor Corps, a Facebook group for people affected by Covid-19 with approximately 171,000 members, conducted an informal survey and found 24 people who said they had persistent symptoms after a breakthrough infection. It is not a scientific sample and the cases have not been validated, but the survey shows that more data is needed on breakthrough cases, Ms Berrent said.

“You can’t extrapolate it to the general population, but it sends a very strong signal that the CDC must mandate coverage of every breakthrough case,” Ms. Berrent said. “We can’t know what we’re not counting.”

However, some experts predict that the surge in new cases caused by the spread of the Delta variant will unfortunately lead to more groundbreaking cases in the coming months. Dr. Chen of Mount Sinai said it would take several months to enroll patients with long covid due to a breakthrough infection.

“We are waiting for these patients to show up at our door,” said Dr. Chen.

Despite the lack of data, one thing is clear: vaccination reduces the risk of getting infected and developing Covid, Athena Akrami, a neuroscientist at University College London, said the data from nearly 4,000 long-term Covid patients developed after long Covid collected and released after a battle with Covid-19 in March 2020.

“It’s simple math,” said Dr. Akrami. “If you reduce infections, the likelihood of long-term Covid illnesses automatically decreases.”

Scientist who helped develop Pfizer-BioNTech Covid vaccine agrees third shot is required as immunity wanes

Scientist who helped develop Pfizer-BioNTech Covid vaccine agrees third shot is needed as immunity wanes

BioNTech’s chief medical officer told CNBC on Wednesday that people will likely need a third shot of its two-dose Covid-19 vaccine to lower immunity to the virus. This is in line with previous comments from Pfizer CEO Albert Bourla.

Dr. Ozlem Tureci, co-founder and CMO of BioNTech, who developed a Covid vaccine together with Pfizer, also assumes that people need to be vaccinated against the coronavirus every year, for example against seasonal flu. That’s because scientists expect vaccine-induced immunity to the virus to decline over time.

“We see evidence of this in the induced, but also natural, immune response against SARS-COV-2,” she said during an interview with Kelly Evans of CNBC in “The Exchange”. “We see this decrease in immune responses also in people who have just been infected and therefore [it’s] also expected with the vaccines. “

Tureci’s comments come after Pfizer CEO Albert Bourla said in an interview broadcast on April 15 that people will likely need a booster shot or third dose of the Covid-19 vaccine within 12 months of being fully vaccinated. He also said that there is a possibility that people will have to take extra shots every year.

Pfizer said earlier this month that its Covid-19 vaccine was more than 91% effective against the virus and more than 95% effective against serious illness up to six months after the second dose. Moderna’s vaccine, which uses technology similar to Pfizer, has also been shown to remain highly effective after six months.

The researchers say they still don’t know how long protection against the virus will last after six months of full vaccination, although public health officials and health experts believe that protection will wear off after some time.

Should Americans need booster vaccinations, the US government would likely need to reach agreements with drug manufacturers to provide additional doses and make plans to distribute vaccines.

On Friday Andy Slavitt, senior advisor to President Joe Biden’s Covid Response Team, said the Biden administration was preparing for the potential need for Covid-19 vaccine booster shots. He said the government was considering the need to secure additional doses.

“I can assure you that as we plan, if the President orders the purchase of additional vaccines, as he has, and if we focus on all of the production expansion opportunities that we are talking about, we have a great many such scenarios in mind have. “he said.

Last week, David Kessler, chief science officer for the Biden government at Covid, said Americans should expect to receive booster vaccinations to protect against coronavirus variants. He told US lawmakers that currently approved vaccines offer high levels of protection, but that new variants may “question” the effectiveness of the shots.

“We don’t know everything right now,” he told the House Select subcommittee on the coronavirus crisis.

“We are investigating the durability of the antibody response,” he said. “It seems strong, but that’s wearing off a bit, and no doubt the variants are challenging … they make these vaccines work harder. So I think for planning purposes, planning purposes only, we should expect us to may have to. ” Boost. “

Stephane Bancel, CEO of Moderna, told CNBC last week that the company hopes to have a booster shot for its two-dose vaccine in the fall.

UK PM Boris Johnson pronounces 100-day goal to develop new vaccines

UK PM Boris Johnson announces 100-day target to develop new vaccines

LONDON – UK Prime Minister Boris Johnson will call on the leaders of the world’s largest economies to support efforts to accelerate the development of new vaccines.

Johnson, who will chair a virtual meeting with G-7 leaders on Friday, is expected to outline an ambition to cut the time it takes to develop new vaccines by two-thirds to 100 days.

A Downing Street statement said developing a coronavirus vaccine in around 300 days is a “great and unprecedented global achievement”.

“By further reducing the time it takes to develop new vaccines against emerging diseases, we can potentially prevent the disastrous health, economic and social effects of this crisis,” the government said.

The Coalition for Innovations to Prepare for Epidemics first proposed this 100-day goal earlier this year.

“The development of viable coronavirus vaccines offers the tempting prospect of a return to normal, but we must not rest on our laurels,” Johnson said ahead of the meeting.

“As leaders of the G7 today we have to say never again,” he added, calling on the coalition of leaders to use “collective ingenuity” to ensure that “vaccines, treatments and tests are ready to fight future health threats”. “”

Johnson has asked UK Government Chief Scientific Advisor Patrick Vallance to work with international partners including the World Health Organization and CEPI, along with industry and science experts, to help the G-7 accelerate the development of vaccines, treatments and tests to advise.

At Friday’s session, Johnson will also confirm the UK will share the majority of all future excess coronavirus vaccine doses with Covax. This is a global initiative jointly led by WHO and CEPI, among others, and aims to provide low-income countries with fair access to coronavirus vaccines.

On Friday, the EU announced that it would double its contribution to Covax to 1 billion euros (1.2 billion US dollars), while Germany pledged a further 900 million euros for the initiative, according to a statement by the European Commission, the EU’s executive branch.

Unequal guidelines for Covid vaccines

A Lancet paper released late last month highlighted that the 2 billion doses of vaccine allocated to low-income countries under the Covax Accelerator Program in 2021 represented only 20% of the vaccine needs of the countries participating in the program.

The paper followed a warning from the World Health Organization’s top official that the world was on the verge of “catastrophic moral failure” due to unequal Covid vaccine policies.

Dr. Tedros Adhanom Ghebreyesus on Jan. 18 condemned what he called the “first-me” approach from high-income countries, saying it was self-destructive and endangered the world’s poorest and most vulnerable.

Almost all high-income countries have prioritized the distribution of vaccines to their own populations. The international aid group Medecins Sans Frontieres has described what we are seeing today in terms of global access to vaccines as “far from an image of justice”.

The meeting on Friday will be the first in the UK’s “G-7 Presidency” in 2021. It will also be President Joe Biden’s first major multilateral engagement.

Johnson had drawn up a five-point plan to prevent future pandemics at the United Nations General Assembly last year. This will be the focus of the UK G7 Presidency on Friday.

Hyundai, Kia shares fall; say not in talks to develop Apple automobile

Hyundai, Kia shares fall; say not in talks to develop Apple car

South Korean automakers Hyundai Motor and Kia Motors said Monday they were not in talks with Apple to develop an autonomous vehicle.

Hyundai Motor stock fell 6.41% on Monday morning in South Korea, while Kia Motors stock fell 13.2%. Other subsidiaries such as Hyundai Wia, Hyundai Mobis and Hyundai Glovis also fell sharply.

“Hyundai Motor is receiving requests from several companies to collaborate on the joint development of autonomous electric vehicles, but nothing has been decided as it is in the early stages,” the company said, according to a CNBC translation of a regulatory filing.

“Hyundai Motor is not in talks with Apple about autonomous vehicle development,” he added.

Subsidiary Kia Motors, the second largest automobile manufacturer in South Korea after Hyundai, submitted a similar report. The company is currently evaluating the prospect of working with “multiple companies overseas” on autonomous electric vehicles, but nothing has been decided yet.

Kia Motors also said it was not in talks with Apple.

Hyundai initially said it was in early talks with Apple last month, but later revised the statement and made no mention of the iPhone maker. This led to a surge in the shares of Hyundai and its affiliates, including Kia Motors, at the time.

This month, CNBC reported that Apple is on the verge of signing a deal with Hyundai-Kia to manufacture an Apple-branded autonomous electric vehicle at the Kia assembly plant in West Point, Georgia. Sources told CNBC’s Phil LeBeau that an agreement has not yet been reached and that Apple may ultimately decide to work separately or in addition to Hyundai with another automaker.

Stocks can keep falling

According to Sung Yop Chung, private investors have had Hyundai Motor and Kia shares valued at approximately 915.7 billion won (817 million US dollars) and 798.8 billion, respectively, since January 8th speculation about a possible collaboration with Apple Won (around $ 713 million). Regional Head of Automobiles and Components at Daiwa Capital Markets.

“After the negative sentiment from both (Hyundai Motor) and Kia’s filing this morning highlighting that there is currently no EV collaboration with Apple, worst case scenario suggests Kia’s shares could correct up to 31%” he told CNBC’s Chery Kang.

Speculation about Apple’s entry into the auto business has been rife for several years, but nothing specific has occurred.

Some Wall Street analysts see the automotive industry as a new market for Apple to grow into, but others caution against the reality of making an Apple-branded car as it could potentially mean high investments for low margins.

Small Variety of Covid Sufferers Develop Extreme Psychotic Signs

Small Number of Covid Patients Develop Severe Psychotic Symptoms

Brain scans, spinal fluid analyzes, and other tests did not reveal any brain infection, said Dr. Gabbay, whose hospital has treated two patients with postcovid psychosis: a 49-year-old man who heard voices believing he was the devil and a 34-year-old woman who started carrying a knife, undressing in front of strangers, and putting in hand sanitizer to give her food.

According to reports, most of these patients did not get very sick from Covid-19. The patients Dr. Goueli did not have any breathing problems, but they had subtle neurological symptoms such as hand tingling, dizziness, headache, or decreased odor. Then, two weeks to a few months later, they develop “this profound psychosis that is really dangerous and scary for everyone around them”.

It is also noticeable that most of the patients were between 30, 40 and 50 years old. “It is very rare for you to develop this type of psychosis in this age group,” said Dr. Goueli, since such symptoms are more likely to be associated with schizophrenia in young people or dementia in older people. And some patients – like the physiotherapist who took herself to the hospital – understood that something was wrong, while “people with psychosis usually don’t know that they have lost touch with reality”.

Some post-Covid patients who developed psychosis had to be hospitalized for weeks, where doctors tried different drugs before they found one that worked.

Dr. Robert Yolken, a neurovirology expert at the Johns Hopkins University Medical School in Baltimore, said that while people can physically recover from Covid-19, in some cases their immune systems may not be able to turn off or due to “Delayed elimination of a small amount of virus. “

Persistent immune activation is also one of the main explanations for brain fog and memory problems that plague many Covid survivors, and Emily Severance, a schizophrenia expert at Johns Hopkins, said that post-Covid cognitive and psychiatric effects may be due to “something similar in the brain “Are due.
