[A calendar of prophylactic inoculations in wide practical use].

The validity of immunizations, made in due time in children aged up to 7 years in accordance with the approved immunization schedule, is analyzed in this work. The content of antibodies to diphtheria, tetanus and poliomyelitis antigens in children immunized in accordance with the old and new schedules has been studied. This study has revealed that the injection of adsorbed DPT vaccine to children aged 3-4 months induces fully valid immune response to all antigens under study. The level of measles and parotitis antibodies after the injections of measles and parotitis vaccines, introduced separately and simultaneously, has been measured. The simultaneous administration of these preparations did not decrease the levels of immunity to parotitis and measles.
