[Combined use of a specific vaccine and interferon inducers for preventing and treating experimental tick-borne...

A comparative study of prophylactic and therapeutic activity of 6 Soviet interferon inducers in tick-borne encephalitis was carried out. Such inducers as double-stranded RNA, poly(G) . poly(C), and tyloron were most active prophylactically. A therapeutic effect was observed after combined use of specific vaccine and interferon inducers: double-stranded RNA and poly(G) . poly(C) which underwent clinical trials. When these inducers were administered 3 hours after infection the protective effect was 56.7% and 46%, respectively.
