A puppy will not develop parvo from the vaccine itself but could still acquire parvo is exposed. If Luisa only had that one vaccine she would not be fully protected against parvo. Even if that vaccine was a booster of previous vaccinations, no vaccination series is 100% preventative.In some cases a weaker immune system or large exposure may still result in getting the disease even if adequately vaccinated. In many cases previous vaccination may result in less severe disease. Good luck. I hope Luisa is better soon. Thanks for using Petco Pet Education Center, formerly Petcoach.

    If your puppy had a full course of vaccination it is very very unlikely that he would get parvo, but there are many other gastrointestinal infections that can look like Parvo, they are usually much milder though.
