Do adults need vaccinations

Babies are coming... loads and loads of babies and someone said something about wanting everyone up to date on their t-dap shots if they’re gonna be around the baby so I’m making an appointment Monday to do that.

I know that I was vaccinated for everything as a kid. So do all those vaccines last a life time or do you have to get vaccinated again later on in adulthood? She said that and I was like oh crap I am going to be around 6 newborn babies soon I need to make sure I’m good on everything. I know the flu shot is every year but I already got that down.
