TDAP Vaccine as an Adult

1965_Bruce

My doctor in the course of regular exam advised me to get the TDAP vaccine. He said adults should have it once. The thing is, I don't remember if I had it. If I did at all it would have been in my 20s possibly close to 30 years ago and I don't remember. If somehow I did have it, will it hurt me to get it again? Also, I read that there is something called a Booster for those who had it, should I be getting that?

He said that there's a resurgence of these diseases and all adults should be vaccinated. Any thoughts on this? Is there anything I should know about it or any reason not to get it? I'm pretty sure my parents had me vaccinated as a kid especially if school required it but don't think I've had any adult vaccinations.
