It sounds like Linda was bitten on the hand by Jenny, and her mom has decided to bring her to the vet for a vaccine, likely as a precaution against infection or rabies, depending on the circumstances.
Bites, even from animals we know, can sometimes lead to infections due to bacteria in the animal’s mouth. In some cases, depending on the type of animal and the situation, a vet may also administer a rabies vaccine or check for other potential health risks.
If Linda is a pet, like a dog or cat, this visit to the vet could ensure that she’s properly treated and protected. If Jenny is another pet or even a wild animal, a vet visit is important to make sure Linda doesn’t suffer any complications from the bite.
