[Increase in the effectiveness of anti-influenza immunization by use of a combination of inactivated and live vaccine].
The authors applied a new principle of effective immunization against influenza using a moderately attenuated live vaccine which after 5 passages in developing chick embryos had retained a high reproduction activity in the human upper respiratory tract, while the vaccines were not contagious for their susceptible contacts. The safety of intranasal adminstration of the new vaccine is achieved by giving it to primed subjects previously given oral immunization with the same vaccine or intranasal administration of the standard hyperattenuated vaccine. Since the current inactivated influenza vaccine is the standard hyperattenuated vaccine. Since the current inactivated influenza vaccine is not sufficiently effective epidemiologically, the authors use additionally a single intranasal administration of a highly immunogenic live vaccine. The combined immunization with killed and live influenza vaccines proved to cause no reactions and to be highly immunogenic. Intensive humoral immunity was observed to develop in 86% of vaccines, this genic. Intensive humoral immunity was observed to develop in 86% of vaccines, this figure exceeding considerably the results of administration of the inactivated vaccine alone.
