Many recommend an additional 16 week vaccination as the antibodies from the puppies mother can still effect the 12 week vaccination providing proper immunisation???. Our vet dismissed this suggestion claiming that the type or brand of vaccine they use doesn't need it repeated at 16 weeks???.
I have read several accounts where puppies have had their 6 and 12 week shots but contracted Parvo and died from the virus around 5 or 6 months old that was perceived as being preventable had they had a booster administered at 16 weeks??? I am interested to hear some thoughts an opinions regarding puppy immunisation
