“Fortunately, no vaccines with serial numbers reported from Europe have been imported in Korea, and no case has been reported as a similar adverse reaction among the 580,000 people who have been vaccinated so far. We will closely monitor foreign reactions and take prompt action if there are any signs of abnormality.”
The quarantine authorities announced on the 13th when AstraZeneca (AZ) temporarily suspended vaccination against the novel coronavirus infection (Corona 19) due to an abnormal reaction to the formation of blood clots (blood clots) in some European countries. Not only Korea, but also the World Health Organization (WHO) and the European Medicines Agency (EMA) said that the causal relationship between blood clots and vaccines has not been identified, and that vaccinations should be continued. The opinions of experts were asked whether blood clot formation was not related to the vaccine, and whether it would be okay if the vaccine with the corresponding serial number did not enter Korea.
Blood clots due to vaccine? “Difficult to find a theoretical basis”

First of all, experts contend that the likelihood of the formation of blood clots from the vaccine is very low. A blood clot is a clot of blood. If the clot blood clots blood vessels in the lungs or heart, there is a possibility of sudden death. “It is difficult to find a theoretical basis for injecting a single dose (0.5㏄) of a vaccine to cause a blood clotting reaction in the body,” said Jeong Ki-seok, a professor of respiratory medicine at Hallym University Sacred Heart Hospital. It is difficult to imagine medically.” Professor Jeong said, “In the human body, coagulation and anticoagulation systems work. When a blood clot occurs after getting a vaccine, the anticoagulant system works and dissolves the blood clot. “It is difficult for a substance of only 0.5㏄ to completely destroy the anticoagulant system around the body.”
Jeong Jae-hoon, a professor of preventive medicine at Gachon University, said, “There has never been a previous report of blood clots as a result of a vaccine side effect. It is a very rare case.” “As a result of a survey in the UK, it was found that the incidence of thrombosis was not different from normal without vaccination and after vaccination. It’s hard to say that it’s a vaccine-related problem.” In fact, EMA said that among the 5 million people vaccinated in the EU, 30 cases of blood clots occurred, not higher than the natural incidence.

So, is there a possibility that a substance that causes blood clots was introduced in the process of producing the vaccine? The serial numbers of AZ vaccines that were previously problematic in Europe were’ABV 5300′ and’ABV 2856′. Austria stopped distributing the production unit vaccine after a 49-year-old nurse died of a blood clot-forming reaction 10 days after vaccination with the production unit’ABV 5300′ AstraZeneca vaccine. That means it will stop vaccines produced in the same facility. Italy banned AZ vaccination due to a case of blood clot formation at the manufacturing unit’ABV 2856′.
However, Eun-mi Cheon, a professor of respiratory medicine at Ewha Womans University Mokdong Hospital, explained that it is difficult to see that there is a problem in the manufacturing facility. Prof. Chun said, “If an abnormal substance enters a vaccine with a specific serial number, the abnormal substance must appear simultaneously. “It is difficult to see that there is a problem with manufacturing facilities because there are currently one or two people in each country.”

Then, why did people who did not have an underlying disease die due to the formation of blood clots? “It’s not common, but it can occur in healthy people,” said Professor Ki-Seok Jeong. Professor Jeong said, “You can take economy syndrome as an example. If you fly for a long time in the economy class (economy class) of a narrow and uncomfortable airplane, your legs are swollen and numb due to poor circulation, and if this is old, blood clots can lead to death. If there is a factor that can cause blood clots, he explained.
Experts also agreed with the quarantine authorities’ position that vaccination should be continued. Professor Jeong Jae-hoon said, “There will be a lot of cases like this,” he said. “The cause-and-effect relationship has not been proven, but asking to stop vaccination every time it occurs is not to get the vaccine.” Professor Ki-Seok Jeong said, “Even in European countries where AZ vaccine has been discontinued, scientists and medical scientists have no connection. It is the unique judgment of each country to stop, but I think it is correct to continue the vaccination in Korea.”
