A member asked:
If someone has already taken first dose of astra zeneca covid-19 vaccine, is it ok for that person to take pfizer covid-19 vaccine as second dose?
A doctor has provided 1 answer
It is better to take a second dose of the same vaccine as the first one. However, taking a second dose of a different vaccine is better than not taking a second dose. Wish you good health!
