Vaccine Follow - Up Survey Planned For 3 Mil. People

Japan's health ministry plans to conduct a follow-up survey of up to 3 million people who receive coronavirus vaccines to check on any side effects.
Inoculation of medical workers using the Pfizer vaccine will start on Wednesday. The elderly are due to start receiving the shots, possibly in April.
The health ministry plans to begin the survey in April or later, initially targeting one million vaccine recipients to be chosen at random.
The subjects will be asked through social media if they have developed any post-injection symptoms, such as swelling, fatigue and fever of at least 37.5 degrees Celsius.
An expert panel will evaluate the data.
The survey will be expanded to around 3 million people, once the government authorizes and rolls out vaccines developed by Moderna and AstraZeneca.
