There is a distemper vaccination shot; technically, this shot protects dogs against the parvovirus, which is a specific type of virus that causes the infection known as distemper. If you are considering acquiring a dog as a pet, you should familiarize yourself with this vaccination as soon as possible. While distemper is a deadly and very dangerous disease for pet dogs, it is not often a major concern for humans; humans can get the virus, but there are no effects.
