The Tetanus, Diphtheria, Pertussis (Tdap) Vaccine is a combination vaccine that helps protect children from tetanus (lockjaw), diphtheria, and pertussis (whooping cough). These are serious bacterial infections that can cause severe complications, including respiratory issues, heart problems, and even death.
The Tdap vaccine is typically administered to children at the age of 4 to 6 years as a booster dose after the initial DTP series. In some cases, the Tdap vaccine may also be recommended as a booster shot for children 11-12 years old.
