Hello doctor, I would like to know whether I will get infected with covid if I had my booster. I got my booster on 12th of this month and I had pain on injection site, fever,chills, malaise and after 2 days I developed sore throat ,running nose, cough .i was tested positive .so it means my body is weak or my vaccine I s not effective .how many days will it take to develop antibodies after vaccination.
