This study was conducted in order to determine the behaviour of two live attenuated vaccines against aMPV in relation to IgG production, measurable using the CIVTEST TRT ELISA kit, before and after challenge.

 

we can state that the level of IgG production induced by live aMPV vaccines is not a good indicator of the degree of protection, although it may be useful for differentiating between flocks in which high pressure from the field virus persists (with high levels of seroconversion) and flocks in which the vaccine is displacing the field virus.
