Is it necessary to give oral polio vaccination?
Q: My seven months old son has already been administered 3 doses of injectible polio vaccination (IPV). Is it necessary to give oral polio vaccination (OPV)?
A:One booster dose of IPV has to be given around 18 months of age. Also it would be ideal to give the additional OPV doses whenever there is Pulse Polio Programme in your area.
