Antibody to poliovirus in older children and young adults in Israel and the use of poliovaccines for the immunization of the seronegatives.

This report represents preliminary results of a more extensive study which is presently being carried out in Israel. The main aims of this study were twofold: (1) to carry out a survey of the state of immunity of children of various ages and of teenagers to the three poliovirus types and (2) to compare the antibody response of the seronegatives to the two kinds of presently available poliovaccines, the oral poliovaccine (O. P. V., Savin Vaccine) and the inactivated poliovaccine (I. P. V., Salk Vaccine).
