We vaccine dogs against Parvovirus but why is there no vaccine for the human strains?
In: Biology
Parvo is a lot more virulent and dangerous for dogs than it is for humans. Knowing that we can only persuade people to have so much intervention for something that won’t kill them…
They’re just very different in how virulent they are.
[The one that infects dogs (and cats)](https://en.wikipedia.org/wiki/Canine_parvovirus) causes severe to deadly disease in most. That’s well worth preventing.
[The one that infects humans](https://en.wikipedia.org/wiki/Parvovirus_B19) causes mild or no disease in most, other than those who are already immunocompromised or have other comorbidities. There’s much less benefit to be had from a vaccination program.
