In general, it will not harm a puppy to have vaccinations twice unless it is a vaccine that the animal has a reaction to. Of course, we don't recommend that you get the vaccines off schedule, but most vaccines are tested so that if they are given at a higher than usual dose, it will not be harmful to the animal. Your pet may be more lethargic, painful at the injection site, etc etc, but in terms of serious side effects, you should be OK as long as there are no actual adverse side effects or reactions to the vaccine itself.
