U.S. virus experts speculate on the principle of vaccine-induced thrombosis, which induces the human immune system to produce antibodies. 

U.S. virus experts speculate on the principle of vaccine-induced thrombosis

The Javits Center is one of the three large-scale vaccination sites in New York State and will provide Johnson & Johnson single-dose vaccine injections from March 4th.

On April 13, the U.S. Food and Drug Administration (FDA) and the U.S. Centers for Disease Control and Prevention (CDC) urgently suspended Johnson & Johnson’s vaccination due to thrombosis in six vaccinators.

On the same day, the center suspended the injection of the vaccine. New Yorkers who have made an appointment but have not been vaccinated can still go there at the scheduled time, and the center will use Pfizer instead of Johnson & Johnson vaccine.

New Yorker calmly vaccinated after thrombosis

At the gate of the Javits Center, Kevin Anson, a New York citizen, told reporters that he would not shake his confidence in the vaccine because of the thrombotic incident. He said that compared with the vaccine doses that have been distributed, the proportion of adverse reactions is extremely small, and there is no need to panic. On the day of the interview, he was waiting for the first dose of Pfizer vaccine. “I hope to return to normal and resume work as soon as possible. I have not been to work for nine months.”

 

According to CDC’s real-time data, as of April 18, about a quarter of Americans have completed full vaccination, and 39% of the population have received at least one dose of the vaccine. Among the population who received one dose, those who received the Johnson & Johnson vaccine were close to those who received the vaccine. 7 million.

The six thrombosis cases in the United States were all women aged 18 to 48 who developed thrombotic symptoms 6 to 13 days after receiving the Johnson & Johnson vaccine.

One of them died and the other was critically ill. CDC Deputy Director Anne Schuchat recently stated that people who received the Johnson & Johnson vaccine a month ago have a low probability of developing blood clots, and those who have received the vaccine in recent weeks should pay attention to whether they experience severe headaches, abdominal pain, leg pain or shortness of breath.

If you do have the above symptoms, you should contact a medical institution for treatment in time. She also said that people vaccinated with Pfizer and Moderna have not reported cases of blood clots.

U.S. virus experts speculate that thrombus is the culprit

Is there a causal link between the COVID-19 vaccine and thrombosis? Dr. Robert Gallo, co-founder and director of the Institute of Human Virology at the University of Maryland School of Medicine, co-founder of the Global Virus Network Center and international scientific adviser, AIDS pathogen discoverer Dr. Robert Gallo said that some of Johnson & Johnson’s and AstraZeneca vaccines The ingredients may induce the human immune system to produce an antibody, which in a very small number of people can cause heparin-induced thrombocytopenia (HIT), a life-threatening complication of heparin exposure. “

The mechanism and probability of occurrence are not yet clear. It may be a genetic defect in the human body. After exposure to heparin, people with the above-mentioned defects will have a reaction that is completely opposite to that under normal conditions. Heparin does not have an anticoagulant effect, but accelerates thrombosis. The formation of the best blood thinner has caused thrombosis.”

On April 14, the CDC expert team held an emergency meeting to discuss whether to extend the suspension period of Johnson & Johnson vaccine and how long. Some experts suggested that the vaccine should be stopped for one month. Other experts believed that the vaccine could be limited based on age or other risk factors. use. The CDC finally decided that more data is needed to assess vaccine risks.

Dr. Gallo suggested that the FDA and CDC’s investigation direction could be the association between vaccine components and abnormal heparin reactions. “If the thrombosis is indeed caused by heparin, then it is hoped that vaccine manufacturers will exclude heparin from the vaccine components, or the medical community will design An antibody test to screen out people who have adverse reactions to heparin.”

He also said that he will not refuse vaccination due to individual cases of thrombosis, but believes that it is wise to temporarily stop related vaccines until the cause is investigated. Lift.

On April 18, White House Chief Medical Adviser Anthony Fauci predicted in an interview with foreign media that the CDC will make a decision on whether to resume the use of Johnson & Johnson vaccine as soon as this month on the 23rd. “I estimate that the United States will continue to use Johnson & Johnson vaccines in some way, and may provide warning instructions, risk assessments, or limited use of vaccines.”

Vaccination is accelerating, and the number of newly confirmed diagnoses remains high

Currently, the United States is vaccinating at a rate of 3.3 million doses per day. President Biden promised to ensure that all American adults are eligible for vaccinations before May 1. At the same time, the epidemic situation in the United States is on the rise, with the daily average number of confirmed cases at 70,000 in seven days.

When asked why the improvement of the vaccine did not bring about an improvement in the epidemic situation, Dr. Gallo explained, “It may be because the virus has mutated, it may be because the efficacy of existing vaccines is insufficient, or it may be that people relax their vigilance after vaccination and expose themselves to risks.

Those who have not been vaccinated are at higher risk.” As for when it will be close to normalization, it has been 13 months since the epidemic raided the United States. Dr. Gallo still cannot give an answer. “There are cases of secondary infection in the United States. This tells people that even if a certain degree of immunity is generated, they may not be fully protected.

The vaccine does have a preventive effect, but it is unknown whether it will be effective against all mutant strains. The time for normalization is still predicted. It’s too early.” He said that the necessary conditions for making predictions are, firstly, universal vaccination, and secondly, the need to prove that the existing vaccines can effectively fight against all mutant strains while reducing the infection rate. The above process will take several months.
