To wonder if cats (including outdoor ones) really need annual vaccinations every year?

[lookingforshoes]

Please note: I vaccinate my cat, and I am very happy to continue to vaccinate my cat. She is doted upon and I take far better care of her than I do myself tbh! So please don’t come after me.

That said, I am wondering, hypothetically, how necessary annual vaccinations really are for cats? Would they not build up a good level of immunity after the first few jabs and thereafter need a booster every few years?

I always do as my vet advises, but just thinking about it, it would be in the interests of veterinary pharmaceutical companies to recommend regular vaccination wouldn’t it, so long as it didn’t actually do any harm. But is there really any benefit?

Same as a lot here. I've had outdoor cats my whole life. Always have the kitten jabs and then don't bother after that. All cats (except 2 that have died by car) have lived until 18-20 years old.
