Abstract
The ability of rabies virus ribonucleoprotein (RNP) to induce protective immunity against rabies and to prime for production of virus-neutralizing antibodies (VNA) was studied in monkeys. Following two immunizations with RNP, monkeys developed a strong anti-RNP response and were protected against a challenge infection with a lethal dose of street rabies virus. Monkeys that were primed with RNP and then immunized with a single dose of human diploid cell vaccine (HDCV) developed VNA titres comparable to the VNA titres in non-primed monkeys after a second HDCV immunization. The utility of rabies RNP for the pre-exposure prophylaxis of human rabies is discussed.
