Do rats need vaccination?

Question
I have a pet rat and i don't know if he is vaccinated. Do I
need to get him a vaccine? and what kind of vaccination?
Please provide me some details.

Answer
 Pet rats do not need vaccinations =)  They don't get any diseases that can be vaccinated against, and even the chance of them getting a disease is very rare unless you take them to places where there are a lot of other rats which is unlikely.  I hope that answers your question, good luck with your rat!
