For pregnant women it is recommended get two vaccines during every pregnancy: the inactivated flu vaccine (the injection, not the live nasal flu vaccine) and the Tdap vaccine. Flu vaccine is recommended during flu season. Flu vaccines have been given to millions of pregnant women over the years, and scientific evidence shows that it is safe. While the American CDC recommends to get the Tdap vaccine between 27 and 36 weeks of each pregnancy, in Singapore the recommended period is between 16 and 32 weeks gestation. While Tdap vaccine protects against tetanus, diphtheria and pertussis (whooping cough), the main benefit is to provide passive immunity to your baby from whooping cough.
I had a flu vaccine at KK hospital.
