Distemper parvo vaccines are usually given every 3 weeks until they are 15-16 weeks old so he likely got a booster of the same or similar vaccine as he received when he was 7 weeks old. This is normal and not going to harm him either way. Today's vaccine should be effective whether or not he received one at 7 weeks old. He will need another distemper parvo vaccine in 3 weeks and again in 6 weeks from now. Your vet will also recommend some other vaccines dpenedent on your area. I would not take him to public places like a dog park or pet stores until he is completely vaccinated. I hope this helps!
