Based on the results of 2013, according to Rospotrebnadzor, 39.3 mln people received preventive vaccination against influenza and about 12.7 mln of them were children (under 17 years of age). An unstable situation regarding immunization of the population was observed during the research period. It was associated with multiple factors including but not limited to:

• The lowest vaccination rates of the population were reported in 2005 – 17.6 mln people; this situation was caused by a lack of funds for preventive measures.

In 2006-2007, when influenza vaccines were added to the National Immunization Schedule, the vaccination rates increased and, as a result, the population coverage by preventive immunizations also showed some rise.  

• A mild decline in the vaccination rates (by 4.3 mln people) was reported for 2008. It occurred because the domestic producers were unable to accomplish a plan of vaccine supplies, since the estimated immunization coverage within the National Project “Health” was 27 mln people.

• In 2009-2010 a significant growth of vaccination rate was observed (approx. two-fold vs. the previous year) as a result of the increased funding for preventive measures and the enhanced production capabilities of Russian companies, as well as the implementation of vaccination campaign against two types of influenza virus. 

• In 2011-2013, the immunization against a pandemic influenza strain was not conducted and, in turn, it affected vaccination rates. According to Rospotrebnadzor, in 2013 about 37.3 mln individuals received annual vaccination (˜28% coverage), which is similar to the rates of vaccination against the seasonal flu in 2009-2010.
