The objective of the study was to determine significant differences in the levels of antibodies against the disease caused by aMPV between unvaccinated batches (G0), batches vaccinated with one dose of inactivated vaccine (G1), and batches vaccinated with two doses of inactivated vaccine (G2) as recommended in countries where the use of live vaccines is not permitted.

We can conclude that in countries where live vaccines against aMPV
cannot be used, the serological behaviour against aMPV in birds
vaccinated with 2 doses of HIPRAVIAR® TRT /AVISAN® TRT (G2) is more
predictable and less conditioned by the field challenge than in
unvaccinated birds (G0) or in those vaccinated with a single dose (G1).
