In Korea, one case of a blood clot was reported to the quarantine authorities among people who died after receiving the AstraZeneca novel coronavirus infection (Corona 19) vaccine. Authorities estimated that there was no association between thrombosis deaths and vaccination.

In a back briefing on the 17th, Kim Jung-gon, head of the vaccination investigation team, said, “In this case (death of a woman in her 60s vaccination), there is a long-term underlying disease, and respiratory system diseases such as aspiration pneumonia and acute myocardial infarction are the main causes. It is difficult to determine the death from vaccination,” he said.

After receiving the AstraZeneca Corona 19 vaccine, the person reported to have formed a blood clot is a woman in her 60s who was admitted to a nursing hospital. “When the investigation team collected additional data, it was judged that they could die with only two causes, as they also had findings related to acute heart cases and myocardial infarction, in addition to aspiration pneumonia,” said Kim Jung-gon (Professor of Seoul Medical Center), said Explained. “There has not been a direct relationship between thrombosis and AstraZeneca vaccination,” he said.

It is judged that there is no clear basis for stopping the AstraZeneca vaccination so far. “It has been reported that blood clots have occurred after vaccination in the case of the influenza flu vaccine, as well as the corona 19 vaccine,” he added. “The final result was reported that the AstraZeneca vaccine was not related to the occurrence of blood clots.” .

Thrombosis is a disease caused by a clump of blood in the blood vessels. Looking at current overseas statistics, the frequency of thrombosis is about 100 per 100,000 people. “The higher the age, the higher the risk of blood clots,” Kim Jung-gon said. “Thrombosis occurs in up to 500 people per 100,000 people in the elderly. The risk of death from thrombosis also increases that much.”

In Korea, about 570,000 people have been vaccinated with the AstraZeneca Corona 19 vaccine so far. A second investigation of the deaths of six of the 16 people reported to have died after getting the Corona 19 vaccine in Korea revealed a provisional conclusion that it was not related to the vaccination. Among them, one case of a blood clot was found among people who died from the recent AstraZeneca vaccine. “This patient is undergoing an autopsy,” said Mr. Kim, and said, “The results will be notified by the National Institute of Forensic Science and the police, and we plan to re-evaluate if there are any special issues.”

Currently, some European countries, such as Germany, France, Sweden, and Italy, have stopped vaccination due to concerns about the formation of blood clots after vaccination with AstraZeneca. After vaccination, the vaccination was discontinued until the final results of the emergency investigation by EMA appeared after the occurrence of side effects such as bleeding, platelet reduction, and cerebral thrombosis in which blood clots block the pulmonary blood vessels. However, the World Health Organization (WHO) and AstraZeneca pointed out that there was no connection between the two. The final findings of the expert committee commissioned by EMA will come out on the 18th.

If EMA admits that “AstraZeneca vaccine can cause blood clots,” the government is likely to stop vaccinating once further study results of AstraZeneca are available. In this case, you will have to rely on other vaccines, such as Pfizer. In the first half of Pfizer, only 3.56 million people were introduced. The quantities of Modena, Janssen, and NovaVax, which are scheduled to be introduced around June, have not yet been confirmed. Depending on tomorrow’s results, the first half vaccination plan could also be disrupted.
