Hi Dr Puneet,

Regarding the vaccination.
Baby born on -> July 11, 2013
First vaccine(OPV, BCG, Hep B1 i.e., Pentaxim) -> July 13, 2013
2nd Vaccine (DTP, HiB, HepB2,IPV) -> Aug 28, 2013.

After the we were due for the 3rd vaccine on Sep 28, 2013 For Rotraix, Prevnar and Pentaxim.

But, we have given only Rotrix on Sep 28, 2013 and missed the Pentaxin and Prevnar.

Now, our doc is telling not to give the missed ones immediately and we need to wait at-least 3-4 weeks as the Rotarix antibodies has already started in the body.

So, I am worried if the gap between the two Pentaxims will be too long that is one was given on Aug 28th and now we will be due for Oct 28th? Will this effect my baby immunity?

Cant we give the missed vaccine immediately within a week?

Hi Tulasi,

There is no need to wait for a month. The missed vaccinations can be safely given within a week of Rotarix. There is no problem.

Best wishes,
Dr. Puneet Kumar,
