A hamster doesn't need any shots unless it gets ill.
Bunnies don't need shots
Unless given by a doctor or vet, you should never give a hamster a shot unless they are going to die.
No, tetanus shots are for rusty metal.
Here's a chart that I got from Dogster. This is about the correct time to get what shots and when:
you need 2 but you have to get your grade 7 shots too. :) if you havnt already got them
Two or three
Leaving aside for the moment of exactly what you were doing with your tongue that would place it at risk of being bitten by a hamster... It's going to hurt a lot, and it's probably going to bleed a bit too. It could potentially become infected. You should probably see a doctor... be sure you tell him what happened, because even doctors need a laugh now and again.
they need all of the same shots as othe dogs.
None! Hamsters groom themselves.
YOu only need one.

No rabbit normally needs shots. However, if you are showing your rabbit it could possibly need shots to be shown.
