Regarding Pfizer's new coronavirus vaccine, the Ministry of Health, Labor and Welfare has revealed that seven people who received the vaccine had symptoms such as myocarditis.
Similar symptoms have been reported in the United States, albeit relatively rarely, and the Ministry of Health, Labor and Welfare continues to collect information, saying that "no serious concerns have been found at this time."
According to the Ministry of Health, Labor and Welfare, about 9.76 million people were vaccinated with Pfizer in Japan by the 30th of last month, and seven men and women in their 20s and 60s had myocarditis and pericarditis. There was a report from the institution.
Six of them were male and had symptoms after the second vaccination.
In the United States as well, relatively few people who have been vaccinated with the same "mRNA" have been confirmed to have myocarditis, more often in young men over the age of 16 and after the second vaccination.
The Ministry of Health, Labor and Welfare has stated that "there are no serious concerns affecting the inoculation system at this time," and will continue to collect domestic and international information.
Expert "Infection has a higher risk of developing myocarditis"
Regarding the fact that some people had symptoms such as "myocarditis" after vaccination with the new corona virus, Professor Keiichi Fukuda of Keiichi University, who specializes in cardiology, said, "It is caused by virus infection. Myocarditis is life-threatening when it becomes severe, so it is necessary to be very careful, but this vaccine does not contain a virus, and it seems that the immune response causes inflammation of the heart. It is important to consider the possibility of myocarditis after finishing the procedure, but it is considered that the symptoms are not as strong as those caused by the virus. "
On top of that, "There are a certain number of people who develop myocarditis due to infection with the new coronavirus. As far as the frequency of symptoms after vaccination and the symptoms that are known at this stage are seen, it is infected with the new coronavirus. The risk of developing myocarditis is much higher. I think that the benefits of vaccination far outweigh the risks and should be actively vaccinated. "
More people in the second American CDC survey and younger generations
The CDC = Centers for Disease Control and Prevention in the United States investigates symptoms after vaccination using a mechanism called "VAERS" that can report not only medical institutions but also the person who received the vaccination.
In the United States, as of the 29th of last month, a total of 8,892,000 people had been vaccinated with Pfizer and Moderna, and the causal relationship with the vaccination is unknown at this time, but those who received the second vaccination and young people People of the age group have more reports of myocarditis and pericarditis.
As of 31st of last month, 528 people reported symptoms after the second vaccination, of which 52% were between the ages of 12 and 24.
In addition, among those under the age of 30 who were reported to have symptoms of myocarditis or pericarditis, an analysis of 285 with known conditions revealed that 95% (270) were discharged.
Eighty-one percent (180/221) of those who were able to grasp their physical condition after discharge were completely recovered.
On the other hand, 15 were in the hospital, and 3 of them were in the intensive care unit.
The CDC will meet an advisory committee on immunization implementation on the 18th of this month to further analyze the data.
