Abstract
To investigate the immunogenicity and protective efficacy of cold-adapted influenza vaccine in individuals with underlying immunity to influenza A virus, we administered cold-adapted H1N1 and H3N2 vaccines to adults with prevaccination serum hemagglutination inhibition antibody titers of 1:16 or more and challenged them 1 month afterwards with homologous wild-type influenza A virus. Both cold-adapted vaccines were immunogenic in seropositive adults. In addition, individuals receiving cold-adapted vaccines had lower rates of virus shedding and illness following challenge with wild-type influenza virus than did unvaccinated seropositive volunteers.Entities:
