The seasonal inactivated, split virion, trivalent influenza vaccine (TIV) were purified by the method of super centrifugation to create gradient segments in sucrose sugar produced by IVAC, or placebo produced by IVAC. Vaccines are produced on eggs, inactivated with formaldehyde. The dose of the vaccine tested was 15 mcg of HA for each antigen component in 0.5 ml. The influenza virus strains used to produce the 2020-2021 seasonal vaccine will also be provided by the NIBSC, which will be used according to WHO recommendations, which are expected to include the following Southern Hemisphere strains: Influenza A / H1N1 strain: Recombinant strain IVR-190 44250 E12 of the strain (A / Brisbane / 02/2018). Influenza strain A / H3N2: strain IVR-197 (H3N2) 44850 E14 recombinant strain (A / South Australia / 34/2019). Flu strain B (B / Washington / February 2019). Extensive phase 3 was conducted 2 sites: District Health Center (DHC) of Vu Thu, Thai Binh, Vietnam; and DHC of Binh Luc, Ha Nam. Subjects were from two age groups: 6 months-under 18 years and over 60 years. Both safety and immunogenicity were assessed
