I'm certainly not an expert, but I did attend a vaccine seminar and what your vet is saying about the 16 week mark is similar to what was presented to us. The 16-week mark is said to be the best timing for the vaccines to be given, but we were also told that even if you only had one, it is the one given at the 16-week mark that is the most effective. My understanding is that quantity doesn't matter, but timing does. It seems excessive that your vet wants to give another one after the 16-week age.
