Will vaccination interfere with the FeLV diagnostic tests?
In either a cattery or a multicat household, the most effective procedure is to test by IFA and remove all FeLV-positive cats. The remaining FeLV-negative cats should then be vaccinated and retested every three to six months for the next year, and any that become positive during that time should be removed.
