Guys, there is new vaccine out there by merial that is administered through high pressure jet in the rear leg or tail.
This vaccine is much safer. The dosage is killed/modified, so there is no risk of your cat contracting FeLV or testing positive, unless they already have it. This particular vaccine has been on the market for about a year. It doesn't pose a risk to cats who already have FeLV< but it does nothing to help ward off the disease.
If your cat goes outside or lives with or has been exposed to a cat who has FeLV, you need to do a few things:
1. Have them combo tested immediately. Once they test negative, you may choose to vaccinate them, but ONLY with the Merial vaccine.
2. If your cat goes outdoors or has continuos exposure to and FeLV cat, have them combo tested every 8-12 weeks. If they ever show positive, keep them idoors IMMEDIATELY and begin supplementing the diet with CoQ10 and L-Lysine. Also, consider Immunoregulin or AZT treatments. FeLV is a retrovirus that attacks the immune system and CAN BE REVERSED if the cae is caught while asymptomatic. Only about 30% of cats who get FeLV become persistantly infected, but all of those 30% will have a much shorter lifespan because of it.
This shot is 70%-90% effective and provides immunity for the lifetime of the cat.
Just needed to clear that up. Again, new vaccine= not dangerous, but not entirely neccessary.
