Expert groups recommend vaccinations against Feline Panleukopenia (FPV), Feline Herpesvirus-1 (FHV-1) and Feline Calicivirus (FCV) every three to four weeks until 16 weeks of age in primary series as well as the extension of revaccination-intervals. The purpose of this field study was to evaluate the immune status against these three core components in cats in Vienna, Lower and Upper Austria, to analyze associations between antibody titers and different influencing factors and to get information about schemas of vaccination practice over the study period.
The study population (92 cats) was preselected as only clinically healthy, privately owned cats, that had been presented to a veterinarian more or less regularly, were included. High rates of seroprevalence against FPV (96.7 %, haemagglutination inhibition test), FCV (88.5 %, serum neutralization test) and FHV-1 (96.4 %, serum neutralization test) could be found. Different intervals between the last vaccination and sampling (twelve days up to 15 years) were not significantly associated with antibody levels. Though in cats, that had been vaccinated at most twelve months before sampling, lower antibody levels against FPV were surveyed with increasing age respectively number of vaccinations. The extension of the kitten-vaccination-course up to 16 weeks of age was significantly associated with higher antibody levels against FPV.
Feline vaccination practice was investigated on the basis of anamnestic information of proband cats as well as questionnaires responded by 198 Austrian veterinarians in 2014. This evaluation represented that most cats were younger than 16 weeks of age at the last shot of the kitten-vaccination-course. The majority of veterinarians still administered vaccinations against FPV, FCV and FHV-1 annually (>90 %). Altogether, the results of the study support the current vaccination guidelines for household pet cats (administration of kitten vaccinations every three to four weeks until 16 weeks of age in particular against FPV and triennial revaccination-intervals). However, the vaccination practices of Austrian veterinarians are little consistent with the published vaccination guidelines, but rather seem to correspond to traditional routine.
