I would worry a little more about the new kitten passing on diseases to the older cat - viral upper respiratory infections in particular are common. I'd recommend vaccinating both cats with the FVRCP combo and rabies vaccines. If the cats are going to continue to be outdoors then the FeLV vaccine would also be recommended, and I actually usually recommend vaccinating all kittens for FeLV since you never know if their lifestyle might change.

    Hello and congratulations on your new cat! Cat vaccines 'work' in the same way as dog vaccines. Kittens get FVCRP, FeLV and Rabies. Indoor only adult cats get FVRCP and Rabies. Adult cats who go outside or exposed to other cats who go outside will get FVRCP, FeLv and Rabies. The vaccines need boosters just like dogs and puppies. Cats/kittens may also need and FeLv/FIV test as well. This link explains more: https://www.petcoach.co/article/annual-veterinary-exams-preventive-health-care-in-cats/ I hope this helps.
