I took the covid chinese vaccine 4 months ago and now my country got the pfizer vaccine . i tested my antibodies and they were negative after 4 months of getting sinopharm. can i take the pfizer vaccine now?
A doctor has provided 1 answer
Yes. There is evidence that Pfizer vaccine is more effective. Taking a second vaccine will not do any harm and may be useful. Wish you good health!
