Japan reports 47 anaphylaxis cases after 580,000 Pfizer vaccine shots

Kyodo -- Mar 27
A total of 47 cases of anaphylaxis, a severe and potentially fatal allergic reaction, have been reported after some 580,000 shots of Pfizer Inc.'s COVID-19 vaccine were administered to health workers in Japan, the health ministry said Friday.

All recovered after receiving treatment, according to the ministry, with its panel of experts concluding that there are no serious concerns about the safety of the vaccine at this time.

The figure as of last Sunday implies an anaphylactic reaction rate of around 81 cases per million doses administered, much higher than five cases in every 1 million doses administered in the United States and 20 cases per million in Britain.

However, Japan is further behind in its vaccine rollout, and the rate could change as more people receive shots.
