The system of population protection against influenza.

The complex protection of population against influenza includes: 1. annual mass vaccinoprophylaxis among unvaccinated people; 2. urgent influenza prophylaxis among unvaccinated people; 3. early treatment of influenza. Realization of this system in 1980-1984 in some cities of the USSR resulted in reduction of epidemic influenza morbidity by 20-65%, decrease of annual average influenza and acute respiratory morbidity by 15-20% of the level awaited, i.e. by 200,000 to 300,000 cases per million of citizens. However incomplete accordance of influenza vaccines composition with epidemiological situation, insufficiently wide usage of vaccines and other preparations has not allowed to prevent influenza epidemics in other cities.
