There are no vaccines that can protect you against B virus infection.
If you are in a place where there are macaque monkeys, you should stay away from them so that you do not get bitten or scratched. You should not touch or feed monkeys.
Laboratory workers, veterinarians, and others who may be exposed to monkeys or their specimens have a higher risk of getting B virus. See the section on People at High Risk for Infection for ways to help protect yourself.
