RESUMO

The prophylactic action of polycomponent vaccine B[symbol: see text]-4, prepared from the antigens of opportunistic bacteria, on morbidity rate in acute respiratory diseases (ARD) of bacterial and mixed (bacterial and viral) etiology in 121 children aged 2-5 years, attending pre-school institutions was evaluated. For comparison, a group of 118 children of the same age from the same institutions was formed. The vaccine was introduced after the schedule consisting of 3 intranasal and 6-9 oral administrations made at intervals of 3-4 days. The duration of the course of immunization was 26 +/- 4 days. The prophylactic effect of B[symbol: see text]-4 on ARD morbidity was evaluated by the number of ARD cases and their duration per child. The prophylactic effect of B[symbol: see text]-4 on ARD morbidity lasted 14 months (the term of observation) after immunization and was manifested by a decrease in the number and duration of ARD cases after administration of the preparation, also in a group of highly susceptible children.

RESUMO

The reactogenicity and safety of poly-component vaccine (VP-4), prepared from the antigens of opportunistic bacteria, in the prophylaxis of acute respiratory diseases (ARD) in children aged 2.6-6 years. The vaccine was administered intranasally in 3 administrations and orally in 6-8 administrations at intervals of 3-4 days for a period of 24 +/- 4 days. The prophylaxis of ARD with the use of VP-4 was carried out in 168 children in 4 children's preschool institutions. The control group was made up of 120 children, attending the same institutions. The study revealed that VP-4 had low reactogenicity and induced short-time systemic and local reactions (common cold, cough). The administration of VP-4 at a period of the epidemic rise on influenza and ARD morbidity did not lead to an increase in the frequency and duration of ARD in the vaccinees, as well as to the exacerbation of chronic infection and the allergization of the body.
