My friend Bev sent me the the following comments by Dr. Susan from a Yahoogroups group list on the new FIV vaccine:
1) how will vets be able to differentiate a postive FIV test (which detects > >antibodies) from a cat that has been vaccinated? > >2) the data released to date showed that 67% of vaccinated cats were > >protected against FIV infection when challenged. But only 74% of the > >non-vaccinated cats were infected after challenge - this seems a low > >number, and either indicates that FIV is not as easy to transmit as > >thought, or that the researchers used a challenge method that was > >sub-optimal. When you factor in the 26% of cats naturally resistant to the > >challenge, the vaccine efficacy is probably even lower than 67%. > >3) it is a killed vaccine and therefore undoubtedly will be adjuvanted.
