The puppies recovered, but were seriously sick for some time. This week someone I know in California has a litter that developed Parvo after they were vaccinated too. This litter was vaccinated with Neo-Par. Has anyone else heard of Parvo cropping up? SueT ----------------------------------------------- Vaccines sometimes do not overcome "passive" maternal immunity. (Passive immunity is what the mother passes to the pups) Active immunity is what the pup attains himself, usually thru shots, but sometimes by having the disease itself). The mother's passive immunity in the pups is functioning, and reacts to the vaccine as if is the disease, and destroys the vaccine itself. As the maternal immunity weakens, the vaccines are not destroyed, but confer "active" immunity to the pups. We have found that Intervet's Progard parvo vaccine overrides maternal immunity, and gives the pups active immunity very early on, frequently on the first shot. There IS a difference in the vaccines.
