QS-BHK-P7, street rabies virus, after passages in the BHK cell line, had an in vitro phenotype that distinguished it from its parental virus. Both viruses caused lethal infection in mice by central nervous system inoculation; however, only QS-BHK-P7 killed mice by the intramuscular route. We found four mutations, S23R and H424P in ectodomain of the(More)
Objectives. To assess the immunogenicity of intradermal (ID) booster doses of Purified Chick Embryo Cell rabies vaccine (PCECV, Rabipur) administered to Thai schoolchildren one, three and five years after a primary ID pre-exposure (PrEP) vaccination series. Methods. In this follow-up study of a randomized, open-label, phase II clinical trial, two simulated(More)
Combined active and passive immunization has been established to be an optimal strategy for rabies post-exposure prophylaxis (PEP). Prompt administration of vaccine and rabies immunoglobulin (RIG) can reliably prevent the disease. However, RIG is unavailable and unaffordable in the majority of cases. On the basis of a model experiment using hamsters, we(More)
Sub-passaging of QS-05, a street rabies virus (RABV) isolate, in non-neuronal cells resulted in a virus with higher pathogenicity, QS-BHK-P7. Four full-length cDNA plasmids were constructed and the corresponding recombinant viruses were recovered: rQS-05, rQS-BHK-P7 and rQS05-2475G/rQS-BHK-P7-2475A (made by switching of intergenic P-M between these two(More)
