Tdap (stands for tetanus, diphtheria, and pertussis) vaccine

Tetanus, diphtheria, acellular pertussis (whooping cough) vaccine, sometimes known as "Tdap", is advised for pregnant women at all stages of their pregnancy, even if they have already received it. It should be administered between weeks 27 and 36 of pregnancy. Newborns are especially vulnerable to serious consequences from whooping cough (pertussis), and this vaccine helps prevent them from infection and complications. It is also suggested that anybody who will be in close proximity to the newborn, such as family members and caretakers (for example, babysitters, including teenagers), receive all necessary whooping cough vaccines. If their immunizations are out of date, they should be vaccinated.

Tdap is a dormant vaccine, which means it is manufactured from dead bacteria. You cannot become ill from dead bacteria. Tdap is not the same as DTaP, the vaccination is used to prevent the same infections in children.
