Does sinovac has better restuls though? I think a traditiional vacine like sinovac should be less risky but did they actually do any research? I'm not against sinovac but.. the chinse goverment is not giving proper data so it's hard to test. For me Pfizer seems like a no go for my oldest son, he had covid-19 before and only had mild symptoms, so he already has some antibody now so i don't see the use of taking the side effect risk.
