IMMUNIZATIONS


SAFE IMMUNIZATIONS


Safe immunizations include antigens from killed or inactivated organisms:


Influenza   (all    pregnant    women   in  flu season)
Tetanus, diphtheria, pertussis (Tdap) (all pregnant women irrespective of
their prior history); to maximize the maternal antibody response and passive
antibody transfer to the infant, optimal timing is between 27–36 weeks
gestation. For women not previously vaccinated, if Tdap is not administered
during pregnancy it should be administered immediately postpartum.
Hepatitis B (pre- and postexposure)
Hepatitis A (pre- and postexposure)
Pneumococcus (only high-risk women)
Meningococcus (in unusual outbreaks)
Typhoid (not routinely recommended)
