in my 1st pregnancy, i was not requested for any vaccine. in my 2nd ptegnancy, i was not also requested for any vaccine. i had flu vaccine prior to getting pregnant so that was ok. however, after the requested lab test was done, i was requested to have the hepa vaccine, which was given in the hospital. though my OB is also an infectious disease doctor, i was not requested for tdap or tetanus in my pregnancy. if requested by your OB, you can do it.
