Can you get a vaccine shot twice in a lifetime?

I need to get proof of having gotten a vaccine for measles and german measles and mumps. I know for a fact I got these when I was a child, but I don't know where to get the proof (i live in a foreign country now) so I'm thinking of getting them again, is that safe?

Absolutely.

If you cannot prove you had the vaccinations, get them again. It won't hurt you.

I was recently re-vaccinated for MMR, chicken pox, tetanus, and hepatitis. No problem.

EMT

yes it is safe.

I've gotten two chicken pox ones.
Both were by accident.

Did you try calling the local health department of where you lived as a child or even the school you went to? There can be blood tests done to see if your body has antibodies against the diseases which would prove you had your shots. If all that is too much of a hassle, get them done again and explain that you had them before, from what I have read there are no complications of getting them again later in life.

You should ask a doctor, or someone who knows the details. There are different versions of some of these vaccines.

You can get titers done to measure the amount of antibody in your system to these diseases. That will usually count because if the titers are high enough, you are immune to the diseases. Otherwise, it won't hurt you to get the vaccinations done again.
