Japan will survey the potential side effects caused by various coronavirus vaccines after a total of 3 million doses are administered to the general public, the health ministry said Monday.
The Ministry of Health, Labor and Welfare will invite participants to respond to its survey after inoculation for people aged 65 and older starts on April 1. It plans to track common side effects such as fever and fatigue among three different vaccines, including one by Pfizer Inc. that was formally approved Sunday.

Around 10,000 to 20,000 health care workers are set to begin receiving their first dose of the Pfizer vaccine on Feb. 17. The government will collect and periodically release details about all side effects experienced, regardless of whether the vaccine is the cause.
It will also provide information on the safety of the vaccines garnered from the survey after inoculations begin for the general public.
The survey is expected to cover around 500,000 people per single dose of each version of the vaccine. A total of 3 million doses will be necessary if the government includes doses by pharmaceuticals AstraZeneca Plc and Moderna Inc., alongside Pfizer.
