Part 6 of our vaccination series: how many vaccines at once are too many?

Short answer: There's no practical limit. It's been estimated that the body can response to thousands of vaccines at once, so the combinations we would use in animals (and ppl) are not an issue.

A new series of WormsAndGermsBlog posts about vaccination issues in dogs and cats.

Part 1: What do do with an animal that is overdue.
