Pediatrics/IPV vaccine advice


QUESTION: Hello Dr. Puneet,

My baby is now 4 months old. For Polio, he has been given only Oral Polio (OPV) vaccine till date. Our pediatrician didn't told us about Injectable Polio (IPV) vaccine. Now I came to know that Injectable Polio (IPV) is not an optional vaccine but a mandatory vaccine.

My question is, as my son is now 4 months old and till date he has not been given any dose of Injectable Polio (IPV), so can he be given IPV now at this age or whether its too late to start the IPV now ?

If in case its possible to start IPV at 4 months age, then what will be the IPV catchup schedule now and how many dose can be given at what intervals ?

Sir, I request you to please guide me as I am quite worried about it.

Thanks a lot.

Best Regards,
Ashish Jain.

ANSWER: Hi Ashish,

Yes, IPV should be give to all babies, as per current recommendations of IAP.

For catch up vaccination, only 2 doses are required (instead of usual three)at  MONTHS interval...followed by booster at 16-18 months.

QUESTION: Thanks for the reply doctor.

Can you please further elaborate that in your reply "at  MONTHS interval" means whether 1 months or 2 months interval for doses ?

Also, if we start the IPV vaccine for my son at 4 months age and only 2 doses be given (instead of usual three), then will it have the same immunization effect ?

Thank you.

Best Regards,
Ashish Jain.

Hi Ashish,

I am so sorry for the typo.

It is 2 (TWO) months interval.

YES, it will have same effect.

I would be happy to answer general queries on prevention and treatment of ailments in newborn, infant, toddler, child or an adolescent. Needless to say, it will not be possible to answer any query that requires diagnosing, since it is not possible to examine a child online.
