Purevax Rabies Vaccine- is it better than a 3-year vaccine?

I was wondering if anyone is familiar with the Purevax vaccine for rabies, and if it is a better option than the 3-year regular/adjuvant vaccine?  My vet doesn't carry the Purevax vaccine and she said she thought the 3-year vaccine was better because the Purevax one is only valid for 1 year, so then the cats are getting less injections so it mean less chance of reactions and etc... However I've also heard that the Purevax one is a lot safer for cats than the adjuvant vaccines.

My cat Church has had a reaction to the rabies vaccine before, a small bump which went away after a few weeks and a shot of Benadryl. My other cats thought have not had a reaction, however they have immune system issues and are very prone to allergies which makes me cautious. Also we think the other cats are likely related to Church (they were feral kittens found in the same place 1 year apart and might have had the same mother, she was the same color for sure).

Two of my cats are overdue for their vaccination and so my vet wants to do a 1-year vaccine on them this year and then 3-year next year. I am trying to figure out if this is a good idea or if I should just stick to the Purevax one yearly as a better option?

Hello. I'm going to link you an article that is a good source of information about this subject.

I personally do not vaccinate my cats yearly, and I have mine given the Purevax only.

Thanks for the info. Where I live it's required for all pets to have current rabies vaccinations so I want to use the safest/healthiest option.
I ended up getting the Purevax one done yesterday for my two cats who were currently due, but I'm not sure if I can afford to get it for the other two because of the cost unless I can find another vet maybe that has it whose fees are lower. We had to go to a different vet clinic to get it since my vet doesn't have the Purevax one, my petsitter told me the place she works has it so we went there. The total was $107 per cat (for the shot and exam fee). I know the Purevax one is a little more expensive but I don't know if I can afford to spend over $400 a year on just that one vaccination, in addition to all their other medical bills due to their EGC/immune issues/allergies, the Atopica which three of them are on which is very expensive, and etc...
