Tdap Booster Shot
Tdap (Adacel®, Boostrix®) is a vaccine approved for preventing diphtheria, tetanus, and pertussis (whooping cough) in adolescents and adults. The Tdap booster shot is given as a single, one-time injection. In general, the vaccine should be given only if at least five years have passed since the last DTaP or Td vaccine was given (in some cases, the vaccine can be given sooner).
The antigens and toxoids (substances that cause the body to produce antibodies) in Tdap "trick" the body into thinking it has been exposed to diphtheria, tetanus, and pertussis. The body produces antibodies that will help fight these diseases if future exposure occurs.
As with any booster shot, Tdap can potentially cause side effects. If side effects do occur, they are minor in most cases. Some of the most common side effects include, but are not limited to:
