- Abstract
The influence of ts-phenotype of epidemic viruses and of cold-adapted (CA) reassortant vaccines' strains, appropriately prepared, produced on the human immunogenicity was under investigation. A widespread variability of epidemic viruses' thermal sensitivity sign was established. It was shown that the CA reassortant vaccine strains, obtained through crossbreeding of attenuation donors and of thermally resistant epidemic viruses, are described by a higher immunogenicity. Therefore, the immunogenicity of live influenza vaccines (LIV) can be defined by the ts-phenotype of epidemic parent viruses, which must be sampled for the reassortant vaccine strains not only through searching for samples of antigenically actual viruses but also through search for non-ts-phenotype viruses.
