AstraZeneca Photographs Carry Barely Larger Danger of Bleeding Drawback, New Research Says

People who received the Covid vaccine, made by Oxford-AstraZeneca, were at a slightly increased risk of developing a bleeding disorder and possibly other rare blood problems, researchers reported Wednesday.

The results of a study of 2.53 million adults in Scotland who received their first dose of the AstraZeneca vaccine or the vaccine obtained from Pfizer-BioNTech were published in Nature Medicine. About 1.7 million of the shots were from the AstraZeneca vaccine.

The study found no increased risk of blood disorders with the Pfizer BioNTech vaccine.

The AstraZeneca vaccine is not approved in the United States, but it has been approved by the European Medicines Agency, the top drug agency in the European Union, as well as many countries outside the bloc. However, reports of rare coagulation and bleeding disorders in younger adults, some of which were fatal, led a number of countries to restrict the use of the vaccine to the elderly and a few to discontinue it altogether.

The new study found that the AstraZeneca vaccine was linked to a slight increase in the risk of a condition called immune thrombocytopenic purpura, or ITP, which can cause bruising in some cases but severe bleeding in others. The risk was estimated to be 1.13 cases per 100,000 people who received their first dose up to 27 days after vaccination. This estimate would be in addition to the typical pre-vaccine incidence in the UK, which has been estimated at six to nine cases per 100,000.

The condition is treatable, and none of the cases in vaccine recipients have been fatal, the researchers said. They stressed that the vaccine’s benefits far outweigh the low risk, noting that Covid itself is much more likely than the vaccine to cause ITP

However, the researchers also wrote that while the risks of the AstraZeneca vaccine are low, “alternative vaccines for those at low risk of Covid-19 may be warranted if supplies allow”.

It wasn’t surprising to find ITP in a few vaccine recipients, the researchers said, noting that the risk also increased slightly with those vaccinated against measles, mumps, and rubella, as well as those vaccinated against hepatitis B and flu.

In a comment published with the study, blood disease experts said ITP could be difficult to diagnose and that the possible association needed further analysis. But they wrote, “Still, the risk of vaccination-induced ITP appears to be far less at the suggested rate than the many risks associated with Covid-19 itself.”

The study in Scotland also found a very small increased risk of arterial clots and bleeding that may be associated with the AstraZeneca vaccine. However, the researchers said there wasn’t enough data to conclude that the vaccine has been linked to a rare type of blood clot in the brain called cerebral venous sinus thrombosis. Earlier this year, reports of these brain clots resulted in some countries suspending or restricting use of the vaccine.

The researchers said they couldn’t rule out a link to the brain clots, but there weren’t enough cases to analyze them.

The brain clots are “as rare as chicken teeth,” said Prof. Aziz Sheikh, lead author of the study from the University of Edinburgh, during a press conference.

Similar concerns have been raised about a rare condition associated with the Johnson & Johnson vaccine, which is approved in the US and other countries, particularly in younger women with brain clots and bleeding. Six U.S. cases, including one fatality, prompted federal health officials to order an interruption in use of the vaccine in April. The break was lifted after 10 days and the vaccine was reinstated with a label to warn consumers of the risk of clots and the availability of other vaccines. Several more cases were later identified and doctors were advised to avoid using heparin, a standard treatment, in these cases as it can make the condition worse.

The risk of clotting has led Denmark to reject the use of the AstraZeneca or Johnson & Johnson vaccines.

AstraZeneca and Johnson & Johnson’s vaccines both use so-called viral vectors to deliver genetic material into the recipient’s cells, and some researchers have suggested that the vectors can lead to the rare blood diseases. It is not known whether there is a connection.

The Scotland study authors said they did not know if their results on the AstraZeneca vaccine had any effect on the Johnson & Johnson vaccine, which they did not study.

Russia Seems to Carry Out Hack By way of System Utilized by U.S. Support Company

Hackers connected to Russia’s main intelligence agency secretly seized an email system used by the Foreign Ministry’s international aid agency to dig into the computer networks of human rights groups and other organizations that President Vladimir V. Microsoft Corporation announced on Thursday that they were critical of Putin.

The breach was only discovered three weeks before President Biden’s planned meeting with Putin in Geneva and at a moment of increasing tensions between the two nations – also due to a series of increasingly sophisticated cyberattacks from Russia.

The newly uncovered attack was also particularly bold: By breaching the systems of a supplier used by the federal government, the hackers only this week sent e-mails from more than 3,000 real-looking accounts addressed to more than 150 organizations that are receiving regularly Communications from the United States Agency for International Development.

The e-mail was implanted with code that gave the hackers unrestricted access to the recipient’s computer systems, from “stealing data to infecting other computers on a network,” wrote Tom Burt, a Microsoft vice president, on Thursday evening.

Last month, Mr Biden announced a series of new sanctions against Russia and the expulsion of diplomats for an elaborate hacking operation called SolarWinds that used novel methods to injure at least seven government agencies and hundreds of large American companies.

This attack went undetected by the US government for nine months until it was discovered by a cybersecurity company. In April, Mr Biden said he could have reacted much more strongly but chose “proportionate” because he did not want to “start a cycle of escalation and conflict with Russia”.

However, the Russian response appears to have been an escalation. The malicious activity had only started for the past week. This suggests that the sanctions and any additional covert measures the White House has put in place – part of a strategy to create “seen and invisible” costs for Moscow – have not stifled the Russian government’s appetite for disruption.

A spokesman for the agency for cybersecurity and infrastructure security in the Department of Homeland Security said late Thursday that the agency is “aware of the possible compromise” with the agency for international development and is working “with the FBI and USAID to better understand it. ” Level of compromise and support for potential victims. “

Microsoft identified the Russian group behind the attack as Nobelium and said it was the same group responsible for the SolarWinds hack. Last month, the US government explicitly stated that SolarWinds was the work of the SVR, one of the KGB’s most successful Soviet-era spin-offs

The same agency was involved in the National Democratic Committee hacking attacks in 2016 and previously in attacks on the Pentagon, White House email system, and State Department unclassified communications.

It’s gotten increasingly aggressive and creative, say federal officials and experts. The SolarWinds attack was never discovered by the US government and was carried out through code implanted in network management software that is widely used by the government and private companies. When customers updated SolarWinds software – much like an iPhone would do overnight – they were unwittingly letting in an intruder.

The victims last year included the ministries of homeland security and energy, as well as nuclear laboratories.

When Mr Biden took office, he ordered a study into the SolarWinds case, and officials have been working to prevent future supply chain attacks where adversaries infect software used by federal agencies. This is similar to this case when Microsoft’s security team caught the hackers using a widely used Constant Contact email service to send malicious emails that appeared to come from real-world addresses belonging to the International Development Agency.

But the content was barely subtle at times. In an email sent through the Constant Contact service on Tuesday, the hackers highlighted a message claiming that “Donald Trump had published new emails about election fraud.” The email contained a link that, if clicked, would place malicious files on recipients’ computers.

Microsoft noted that the attack was “significantly” different from the SolarWinds hack and used new tools and craftsmanship to avoid detection. It was said that the attack was still ongoing and that the hackers continued to send spearphishing emails with increasing speed and reach. Because of this, Microsoft took the unusual step of naming the agency whose email addresses were used and posting examples of the spoofed email.

Essentially, the Russians got into the Agency for International Development’s email system by circling the agency and going straight to their software suppliers. Constant Contact manages bulk emails and other communications on behalf of the aid organization.

“Nobelium launched this week’s attacks by gaining access to USAID’s Constant Contact account,” wrote Microsoft’s Burt. Constant contact could not be reached for comment.

Microsoft, like other large cybersecurity companies, maintains a large network of sensors to search for malicious activity on the Internet and is often a target itself. It was instrumental in uncovering the SolarWinds attack.

In this case, Microsoft reported, the hackers’ goal was not to track down the State Department or the aid agency, but rather to use their connections to get into groups that work on the ground – and in many cases, Putin’s most powerful ones Critic.

“At least a quarter of the target organizations were involved in international development, humanitarian and human rights work,” wrote Burt. Although he did not name them, many such groups have exposed Russian actions against dissidents or protested the poisoning, conviction and imprisonment of Russia’s most prominent opposition leader, Alexei A. Navalny.

The attack suggests that Russian intelligence agencies are stepping up their campaign, perhaps to demonstrate that the country would not step down in the face of sanctions, the eviction of diplomats and other pressures.

Mr Biden raised the SolarWinds attack on a phone call with Mr Putin last month, telling him that the sanctions and expulsions are evidence that his government would no longer tolerate an accelerated pace of cyber operations.

Mr Putin has denied Russia’s involvement, and some Russian news outlets have argued that the United States launched the attack against itself.

At the same time, the White House also imposed a number of new sanctions on Russian individuals and assets, including new restrictions on buying Russia’s national debt that will make it difficult for Russia to raise money and support its currency.

“This is the beginning of a new US campaign against malicious behavior by Russia,” Treasury Secretary Janet L. Yellen said at the time.

Tensions over the housing of cybercriminals in Russia increased significantly this month after a ransomware group took corporate networks of the Colonial Pipeline hostage. The attack forced the company to shut down a pipeline that brings nearly half of its gasoline, diesel and jet fuel to the east coast, sparking a spike in gas prices and panic buying at the pump.

Mr Biden said two weeks ago: “We spoke in direct communication with Moscow about the need for the responsible countries to take decisive action against these ransomware networks. ”

Supreme Courtroom takes up main weapons case over proper to hold in public

Media representatives have settled in front of the US Supreme Court building in Washington.

Al Drago | Reuters

The Supreme Court on Monday agreed to hear a major dispute over the second amendment that could determine whether the constitution protects a right to publicly carry arms.

The decision, announced in a resolution, comes after President Joe Biden faces pressure from activists to take action to limit the availability of high-powered weapons amid outcry over mass shootings.

Proponents of increased arms control measures have raised concerns that the country’s highest court, which has a 6-3 majority of Republican candidates, could expand the scope of the second amendment.

The Supreme Court previously ruled that the second amendment protects the individual’s right to carry a weapon in the home for self-defense. Last year it declined to make a substantial decision on its first major case of the second amendment in a decade.

In the case where the court has agreed to hear the New York State Rifle & Pistol Association against Keith Corlett, # 20-843, on Monday, individuals and a state organization are contesting a New York law under which individuals ” Correct Reasons “must be provided in order to obtain authorization to carry a pistol in the open.

Robert Nash and Brendan Koch, the people who brought the suit, both applied for licenses to carry handguns for self-defense and were refused. A district court found that neither man had any reasonable cause for neither facing “special or unique danger” [their] Life.”

A federal appeals court upheld the lower court’s decision not to license the men.

In their appeal, written by former Attorney General Paul Clement, the men argued that New York law was under the precedents of the District of Columbia Supreme Court against Heller ruled in 2008 and McDonald v City of Chicago ruled in 2010 was unconstitutional.

“As this court made clear in both Heller and McDonald’s, the second amendment essentially guarantees the right to keep and carry weapons for self-defense,” wrote Clement. “Like the threats a need for self-defense might create, this individual and fundamental right necessarily extends beyond the four walls of one’s home.”

New York attorney general Letitia James wrote a brief letter to the judges not to admit the case that the New York law was compatible with the Heller and McDonald rulings of the Supreme Court. In McDonald’s, the court wrote that its opinion was not intended to lift certain “long-standing bans” on the use of weapons.

James wrote that New York law has existed in the same essential form since 1913 and “is backed by a centuries-old tradition of state and local measures regulating the public transport of firearms”.

She also wrote, “New York law directly promotes the overriding interests of the state to protect the public from gun violence.”

A decision is expected by summer 2022.
