No, fish are not vaccinated.
If you do buy a new fish, you should put them in a separate tank first before adding them to your main tank and treat them for possible parasites first; you can use a product such as Prazi for treatment.
This should be done any time you have a new fish that you want to add to your established tank as it's easier to treat a 10 or 20 gallon tank with 1 fish in it than it is to treat a much larger tank with several fish (as one new fish can make your entire tank sick)
