Second vaccine for a six week old

Arsh

Hi mommies,

So my kid is 7 weeks old and already a week late on his second dose of vaccine bc of circumcision. It will be a OPV 1, Rota 1, PCV 1 and Penta 1 vaccine. I don’t know if it makes sense but this is the vaccine for a six weeks old. Now wanted to know the after effects of the vaccine. I have heard babies get really bad fever and swelling in the place of injection. Is that true? Just want to be prepared before hand
