I am asking for my 22 months old child.She was given OPV at birth.After that she was given injectable polio. Should l give her pulse polio drops? Her Paed advised not to give oral polio since injectable polio is sufficient and OPV is not necessary . I still have a doubt on this. Should I give OPV? Is pulse polio drops a must?
