The Irreverent Vet Speaks out on “Are Cat Vaccines Safe?”

Are vaccines safe?

This is a question commonly asked by cat lovers. And it is one that they often struggle with. Cat lovers want to do the right thing, protect their cat but at the same time minimize risk of problems to their cat.

I’d like to address this question. I’m the Irreverent Veterinarian. I give you my opinion and speak the truth regardless of if pet owners or other veterinarians like it or not. I have no hidden agenda here.

So the question that I’ll address in this article is…”Are Vaccines Safe” for your cat?

Are Vaccines Safe?

This is a tough one. The answer is – most vaccines are safe and do way more good than harm. However, there are three types of reactions that can occur from vaccines. The first are mild reactions, the second are allergic reactions and the third is serious reactions that are associated with tumor growth.

My Final Thoughts – Are Vaccines Safe?

This is what I believe. The answer is – most vaccines are safe and do way more good than harm if used properly. I do not recommend OVER-VACCINATING cats. I think that most cats don’t need yearly shots (unless required by law such as Rabies vaccine). I think that each cat should be regarded relative to their risk and ONLY the vaccines that truly protect them should be given.

This brings up the question – what vaccines do cats need? I address exactly this question here – Go to What Vaccines do Cats Really Need.
