Moore, G. E., A. C. DeSantis-Kerr, et al. (2007). “Adverse events after vaccine administration in cats: 2,560 cases (2002-2005).” J Am Vet Med Assoc 231(1): 94-100.
Although overall vaccine-associated adverse event (VAAE) rates were low, young adult neutered cats that received multiple vaccines per office visit were at the greatest risk of a VAAE within 30 days after vaccination. Veterinarians should incorporate these findings into risk communications and limit the number of vaccinations administered concurrently to cats.
