"Vaccination during pregnancy protects both the mother and the fetus from infections that can be severe. It even protects infants after birth, while they are too young to be vaccinated!
MOST VACCINES CAN BE GIVEN DURING PREGNANCY
Like most inactivated vaccines, pertussis and influenza vaccines can be given during pregnancy. They are safe and provide adequate protection to pregnant women.
Only live vaccines such as the measles, mumps and rubella (MMR) vaccine and live influenza vaccines are generally contraindicated." - Vaccination and Pregnancy
