摘要

The inhibition of vaccine-induced seroconversion after vaccination is one of the problems associated with measles virus (MV) immunization. In cotton rats, after transfer of human MV specific antibodies, vaccine-induced seroconversion is inhibited. With this model, it was shown that plasmid immunization (although successful in seronegative animals) was inhibited by maternal antibodies. In contrast, immunization via a mucosal surface with a vesicular stomatitis virus expressing the MV hemagglutinin induced seroconversion in the presence of maternal antibodies and subsequent protection.
