The vaccine was produced using a detergent-based (Triton X-100) extraction of aMPV subtype C. Western blot and virus-neutralization analysis confirmed that the aMPV virosomes contained both the fusion (F) and attachment (G) glycoproteins. SPF turkeys were immunized either intranasally (IN) or intramuscularly (IM) with the aMPV virosome vaccine. Vaccination decreased clinical signs of disease and viral load in the respiratory tract following virulent challenge. These results demonstrate that immunization of turkeys with aMPV virosomes can be an effective strategy for control of disease.
