| Sumario: | Abstract. The degree of immunity to polioviruses of three serotypes among children of different ages was analysed on certain "controlled" and "silent" territories of Russia in different periods of Polio Eradication Initiative. It was shown that the levels of immunity of children’s population to polioviruses on "controlled" and "silent" territories had no significant difference. It was stated that on the phase which preceded the certification for the absence of circulation of wild polioviruses, when the National Immunisation Days were conducted in the country, the percentage of eronegative children to polioviruses of different serotypes was low on all the territories of Russia. After Russia as a part of the WHO European region was certified as a polio free country and mass immunisation was stopped thepercentage of seronegative children increased, especially to poliovirus of serotype 3, both on the "controlled" and on the "silent" territories. |
