reaction to vaccines

Question
Hi My cat Smokey got shots for Rabies, DIstemper, and he got a shot of Ivomec for a mite rash he had. He has been on antibiotic for a week. They gave him these shots on Saturday. Today (monday) he has been sneezing more than usual and a bit lethargic --my vet told me to watch him and that since he has been on antibiotics for a week he should be ok. Then a friend told me that he could be reacting to the distemper shot and her friends cat got really sick
Smokey is over 5 and when he was 2 he had an episode of crystals in his urine  

Answer
Well its TOO late for an immediate vax reaction. :) BUT that doesnt mean kitty is not feeling under the weather from them. If he is not feeling better by tomorrow, I'd call the vet and ask to be seen and request some subcutaenous fluids. That may make him feel a bit better. :)
