In some years we studied the blood sera of children of other age groups as well: 5-7, 8-10, 11-15 years old. In 1966, healthy children were not examined due to the fact that from March 1965 to July-August 1966, polio vaccination was not carried out in the Republic.</p>Kazan Medical archiveКазанский медицинский архив
