Co-administration of an adjuvanted FeLV vaccine together with a multivalent feline vaccine to cats is protective against virulent challenge with feline leukaemia virus, calicivirus, herpes virus and panleukopenia virus

In conclusion, the results from this study demonstrate that concurrent or simultaneous administration of these two vaccines resulted in equivalent efficacy; both vaccine administration regimes showing significant differences in clinical scores or lower levels of persistent antigenaemia when compared to non-vaccinated control cats following challenge.
