| Some individuals elect not to vaccinate cats that are strictly
indoors with no exposure to other cats for FELV and FIP. Some recommend
vaccinating only outside cats and catteries for FIP as there is some question
about the efficacy of the vaccine.
Current research indicates immunity from FVRCP and FELV vaccines may
last longer than one year. When the AVMA makes a recommendation about
the frequency of vaccination, this may change. Immunity and challenge
studies need to be verified by more than one institution before reliable
guidelines can be established. Vaccination intervals may increase to 3
years once adequate studies verify consistent immunity for this schedule.
Vaccination Sarcomas: Some cats, one in 5000 in the initial study, developed
a lump at the vaccination site which turned into a highly malignant tumor.
Recent changes in vaccine formulation and giving injections in different
locations instead of all in one spot has greatly reduced post vaccinal
lumps in cats in our practice. Any post vaccinal lump should be removed
immediately while small.
FIV Vaccines- Newest: recommend testing cat to insure a negative. Use
in cats that go out or are exposed to outside cats. May not protect against
all strains.
