Аннотация
Gold nanoparticle conjugates with Vibrio cholerae antigens were synthesized. The animals were immunized with the obtained conjugates. Rabbit polyclonal antibodies to the antigens were obtained, which showed high specific activity. On the model of white laboratory mice, the protective activity of conjugates of cholera antigens with nanoparticles during infection of vaccinated animals was evaluated using a commercial vaccine as a control. It was shown that in terms of immunogenicity, the created prototypes of cholera vaccine using gold nanoparticles as a carrier and adjuvant complied with the production regulations for the Russian national cholera chemical vaccine.
