A member asked:

Could you tell me what happens if you receive two vaccinations that have pertussis within a one year period?

A doctor has provided 1 answer

Boost your immunity: If you get an extra adult tdap (pertussis vaccine combined with tetanus and diphteria) you might have a little more pain at the injection site. If you have never gotten the vaccine before you are boosting your immune system.
