The investigation of the dynamics of changes in neutralizing antibody titers against type 5 adenovirus in the context of vaccination against a new coronavirus infection.

This research focuses on analyzing the dynamics of neutralizing antibody (nAbs) titers against type 5 adenovirus (Ad5) in the adult population of Russia following vaccination against the novel coronavirus infection with recombinant adenovirus type-5 COVID-19 vaccine (CanSino Biologics, China). The impact of the Ad5 vector on nAb titers was investigated using 302 blood serum samples from individuals who received a single dose of the Ad5-nCoV vector vaccine. The research revealed that 33.

Use of hexon as an antigen for the production of monoclonal antibodies capable of detecting multiple adenovirus types.

In this work, monoclonal antibodies to the adenovirus protein hexon were produced, and their biological and diagnostic properties were characterized. The specific activities of the new monoclonal antibodies, with respect to various adenovirus types, were studied by enzyme-linked immunosorbent assay, indirect immunofluorescence, and western blot analysis. The data demonstrate the potential of the monoclonal antibodies developed, namely 4B7 and 6B12, for use in the development of modern diagnostic assays.

GENETIC DIVERSITY OF ADENOVIRUSES CIRCULATING AMONG THE MILITARY IN THE NORTH-WEST REGION.

The contribution of adenovirus (AV) infections to the overall structure of acute viral respiratory infections among young people of draft age can reach as high as 64.6%. Wide dissemination, the incidence of AV-associated pneumonias and lethal outcomes in the case of some complicated infections illustrate the urgency of studying the antigenic diversity of AVs circulating among the military.
