I'm sorry that your question wasn't answered in a timely manner, Anna. Thank you for the thorough history and test results. To answer you directly, the subunit non-adjuvanted vaccines now available are preferable. They're less likely to cause adverse effects and provide a good amnestic response. No, there's no reason to continue vaccinating for FeLV. It's very difficult to infect a cat with FeLV once they're over a year of age. Please note that a subunit vaccine can't activate latent FeLV...only induce more antibodies against FeLV...which really isn't necessary at his age.

My primary concern is that his leukopenia is due to the FeLV sequestered in his bone marrow. A bone marrow analysis including FeLV PCR on the bone marrow should be considered. Please respond with further questions or concerns if you wish.

thank you ***** ,
Marmalade 10 years was given a vaccination this year and shortly afterwards , 2 mnths he started to loose wieght , but the elisa test was negative and the felv Qpcr was 33.53 - attached is the result , maybe this could have had something to do with what the lab said - mild neutrioenia / mod .non specific lymphopnia .... how I can treat this ?
he is happy byt his appetite is becoming less and less.
Re: the vaccinations , I wont vaccinate him anymore then .... the kitten Wonder , wil ask my vet for subunit non-adjuvanted vaccines - excuse me for being so ignorant but what does the difference and what does it mean.... one unit ... indivdual vaccinations?
so should she have a booster for felv plus the other vaccinations ,
Expert:  Dr. Michael Salkin replied 1 year ago.

You're welcome, Anna. Unfortunately, you won't know how to treat without a bone marrow analysis. If FeLV were found in his bone marrow you might consider the immune booster LTCI from T-Cyte in Murietta, California, USA(###) ###-####or see their website here: http://tcyte.com/). His bone marrow might reveal myeloproliferative disease (cancer crowding out the normal cells that produce white blood cells) or an idiopathic (unknown cause) aplasia (lack of production of white blood cells) and these are treated very differently.

Subunit vaccines don't contain live components of the pathogen. They contain only the antigenic parts of the pathogen. These parts are necessary to elicit a protective immune response. We see less adverse reactions when we limit vaccines to just those parts.

Yes, booster the young one for FeLV plus the other core vaccines, repeat in a year, and then every three years thereafter until 8-9 years of age. Please continue our conversation if you wish.

thank you , will digest everything .. my vet has told me that I have to do a urine sample on him . he has less white blood cells.
Expert:  Dr. Michael Salkin replied 1 year ago.

A urinalysis should be part of most diagnostic workups.

Hi Anna,
I'm just following up on our conversation about Wonder & Marmalade. How is everything going?
