Vaccinate for parvo before 6 weeks?

Species: Dog
Breed: labrador
Age: Less than 3 mon
We have a litter of labrador puppies. They are 5 and 1/2 weeks old. Can we vaccinate them for parvo a couple of days before they turn 6 weeks old?




Online vet, Dr. Marie

Dr. Marie replied:

It is not recommended to do a parvo vaccine before 6 weeks of age. It is very unlikely to be of any use.

The reason for this is that the pups will have something called maternal immunity which is some immunity that they have received from their mother. If we vaccinate during this period, the vaccine is not effective.

There is likely no harm in doing the parvo vaccine early but there is really no benefit.
