My 2.5 months baby was vaccinated today, vaccination name is Hexaxim (not sure if painless). The 1st vaccination was provided on 6th week called as Easy6 (painful). I wanted to know if A) the effectiveness is the same in both the cases and the vaccination provided today was it a painless one B) will the baby have fever and swelling like she had during 1st vaccination C) Can we going forward opt for painless vaccines than painful ones.
