Hello doctor my baby boy is 4months old we went to vaccination according to schedule. first time we gave hexacim, pnuemococal vaccine and rota virus for second time we gave pentavalent, pnuemococal, rotavirus, and oral polliio drops. in middle we gave pulse polio also. for thrid time we gave pentavalent, IPV, oral polio, pnuemococal, rotavirus. they said although you have given pulse polio u have to give IPV compulsory in government they miss second schedule. is it correct doctor???
