Relevance. Vaccination remains the basis for the prevention of the most severe infectious diseases, including the prevention of influenza. The large number of vaccines have been developed and applied currently. The role of adjuvant vaccines is growing. Aims: To look back to the history of adjuvant vaccines and review the literature on clinical trials of influenza vaccines Grippol family. Conclusions: This review summarized principal data on adjuvanted vaccines containing Polyoxidonium as adjuvant which has been used for the production of Grippol family vaccines for more than 22 years. Grippol family vaccines show a high safety profile and good immunogenicity for vaccineers, including those with low responsiveness. In 2008 the vaccine Grippol® plus was approved in Russia. It contains a reduced antigen doses and adjuvant Polyoxidonium, but unlike the vaccine Grippol® is free from preservative thiomersal. There are no serious post-vaccination events, unexpected reactions, post-vaccinal complications to the vaccine were reported for Grippol regardless of the examined contingent. The Grippol® plus vaccine effectively induces the immune response. Adjuvanted lowdosed vaccines Grippol® and Grippol® plus are proved to be safe and effective and to have a good prophylactic efficacy being applied for mass immune prophylaxis. In 2018 new tetravalent influenza vaccine of Grippol family – Grippol® Quadrivalent was approved in Russia. Clinical studies (Phase I-II-III) have shown that the vaccine meet the immunogenicity criteria for inactivated influenza vaccines. Phase 3 clinical trials to expand the indications are continuing. The polymer adjuvant in the vaccine is shown to provide a high immunogenicity of low doses of subunit antigens; all Grippol family vaccines have a high safety profile; the dose reduction of viral antigens reduces the risk of adverse reactions for immunized. The adjuvant in the vaccine effectively stimulates an immune response and has no negative impact on the human health. The physicochemical properties of Polyoxidonium (INN: Azoximer bromide) let to consider Polyoxidonium as an universal adjuvant for different antigens.
