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.
