摘要:
Five live virus vaccines against avian infectious laryngotracheitis were studied with regard to safety, immunogenicity and route of administration. Significant differences in virulence between the vaccine strains were found. Reduced virulence was accompanied by a reduction of immunogenicity and capacity to spread.
