[Analysis of the results of serum studies of children and adults for antibodies to the poliomyelitis virus in a multiyear effort at vaccinal prevention of this infection].

The results of testing the blood sera of children and adults for the presence of antibodies to poliomyelitis have shown the low level of immunity to this infection. The authors believe that the main reasons of the tendency towards the decrease in immunity to poliomyelitis, observed in recent years, are the drawbacks of the vaccinal prevention of this infection and the absence of a differentiated approach to the choice of immunization methods under concrete conditions. Mass immunization against poliomyelitis is recommended, especially in the southern and south-eastern regions of the U.S.S.R.
