Immunization of monkeys with rabies ribonucleoprotein (RNP) confers protective immunity against rabies.
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.
