A member asked:
Is sinovac vaccine effective up to six months only?
A doctor has provided 1 answer
We do not have detailed info about Chinese Covid-19 vaccines and Sinovac is one of them and I could not find more info in WHO website. However, I have heard that China has a plan for a third booster dose so we could guess Sinovac' s efficacy is also waning down after 6 months.
