| Abstract: | Influenza remains a serious health problem, annually causing epidemics embracing up to 10% of the population of the world, and at the periods of pandemics this number may rise 4- to 6-fold. In the overwhelming majority of the countries the prophylaxis of influenza is carried out at present out with the use of inactivated vaccines. One of such vaccines is the highly purified split vaccine Vaxigrip (Aventis-Pasteur, France), permitted for use in Russia since 1992. The article contains the review of the data of literature, as well as the materials provided by the authors, which indicate that the preparation has low reactogenicity (also for children starting from the age of 6 months) and high reactogenic properties, leading to antibody formation at protective levels with respect to all three components of the vaccine. The vaccine has been found to ensure pronounced prophylactic efficacy for 70-90% of vaccinees and a decrease in influenza morbidity even in case of using the preparation a week before the onset of the epidemic. This shows the advantage of Vaxigrip in comparison with other inactivated vaccines. |
