Search for optimal scheme for administering live allantoic influenza vaccine.
The effect of vaccine dilution and composition on indices of vaccination activity was studied in a live allantoic influenza vaccine administered intranasally to adults. The vaccine was shown to be usable in a 1:1 (instead of 1:5) dilution without risk of its reactogenicity rising. An inhibition of component A(H3N2) was observed in a bivalent vaccine obtained by combining directly before use two monovalent vaccines, A(H1N1) and A(H3N2). The conclusions and recommendations based on the results of the present study have practical implications in influenza control.
