Vaccines: Pubs/Guidelines for Vaccinating Pregnant Women
"Because of the importance of protecting women of childbearing age against rubella and varicella, reasonable practices in any vaccination program include asking women if they are pregnant or might become pregnant in the next 4 weeks; not vaccinating women who state that they are or plan to become pregnant; explaining the theoretical risk for the fetus of MMR, varicella, or MMRV vaccine were administered to a woman who is pregnant; and
counseling women who are vaccinated not to become pregnant during the 4 weeks after MMR, varicella, or MMRV vaccination. . . . Routine pregnancy testing of women of childbearing age before administering a live-virus vaccine is not recommended. If a pregnant woman is inadvertently vaccinated or becomes pregnant within 4 weeks after MMR or varicella vaccination, she should be counseled about the theoretical basis of concern for the fetus; however, MMR or varicella vaccination during pregnancy should not be considered a reason to terminate pregnancy."
So, you are out of that 4 week period.
In addition, there are no confirmed cases of congenital rubella syndrome (CRS) on women who received the vaccine during pregnancy.
"A registry of susceptible women vaccinated with rubella vaccine between 3 months before and 3 months after conception – the "Vaccine in Pregnancy (VIP) Registry" – was kept between 1971 and 1989. No evidence of CRS occurred in the offspring of the 226 women who received the current RA 27/3 rubella vaccine and continued their pregnancy to term."
Edited to add: the Td is fine. However, your OB may recommend a Tdap when you go home from the hospital to reduce the risk of exposing your baby to whooping cough. Any adults who come in contact with your baby should take it.
And congratulations!
