Antibody kinetics in NDV vaccinated and challenged chickens against APMV-1 measured by different ELISA formats and HI assay. Sera were obtained from ten chickens after immunization with a live attenuated vaccine based on NDV strain “Clone 30” and challenge at day 21 post vaccination (= day 0 post infection) with the velogenic NDV strain “Herts” (panel A). Panel B shows kinetics of six chickens that were not vaccinated before challenge. Antibodies were measured by indirect ELISAs as indicated in the figure legend or by HI assay against the NDV LaSota strain antigen
