[Postvaccinal immunity to polio-viruses of children with chronic renal pathology].

41 children with chronic renal diseases (with different forms of chronic glomerulonephritis or chronic renal failure) previously vaccinated with 5 to 9 doses of oral poliovaccine (OPV) were examined. Analysis of immunity to polioviruses revealed insufficient serologic protection against all three types of polioviruses compared with general population. Algorithm of yearly serologic examination as well as a schedule of additional vaccination against poliomyelitis depending on chronic renal pathology were developed.
