Regarding Moderna's new coronavirus vaccine, the Ministry of Health, Labor and Welfare explained the risks to men in their teens and 20s, saying that in rare cases young men may have inflammation of the heart muscle etc., and Pfizer's vaccine is also available. I decided to make it selectable.

Very rare cases in Japan and abroad of suspected "myocarditis" or "pericarditis", in which inflammation occurs in the heart muscle and the membrane surrounding the heart after receiving the Moderna vaccine, are reported more rarely in younger men. Tends to be.



According to the Ministry of Health, Labor and Welfare, the number of men who reported myocarditis after vaccination with Moderna in Japan was 28.8 per million teens and 25.7 in their 20s by the 3rd of this month. There are about 25 cases per million people and about 16 cases in their twenties.

In response, the Ministry of Health, Labor and Welfare held an extraordinary expert group meeting on the 15th, proposing to recommend Pfizer vaccine to men in their teens and 20s just in case.



On the other hand, the committee members said, "Is it okay to make a" recommendation "even though myocarditis has been reported even with Pfizer's vaccine?" There were a series of cautious opinions.



As a result, the Ministry of Health, Labor and Welfare does not recommend Pfizer vaccines to men in their teens and twenties, but allows them to choose between Pfizer and Moderna after providing information on risks such as myocarditis. I decided to do it.



People who have been vaccinated with Moderna the first time can switch to Pfizer the second time.



The Ministry of Health, Labor and Welfare will inform the local government of this policy and will deliver additional Pfizer vaccines if desired.

Vaccination of Moderna Divided overseas

Regarding the vaccination of Moderna, there are different responses overseas.



According to the Ministry of Health, Labor and Welfare,


Sweden has decided to temporarily suspend vaccination of all people born after 1991 and recommend Pfizer's vaccine instead, as well as


18 to 24 years old in Ontario, Canada. We recommend that you get the Pfizer vaccine at age.



On the other hand, in the


United States, as with Pfizer, we recommend vaccination to all people of the target age, saying that "the benefits of vaccination outweigh the risks for all people, including young people."
