My puppy is 16 weeks old. He has had the distemper vaccination three times and the parvo vaccination three times. How many more times will he need these? He was 14 weeks when he got the last ones (if that makes a difference).
The one for parvo can be put 3 times but the one of distemper when they are puppies, it is sufficient to put it twice. After it, every year your dog should be revaccinate from distemper, parvo, leptospira, etc.
However, the best would be to contact the vet who started the vaccinate protocol, and ask for protocol in your State.
All the best.
