摘要: A subunit vaccine, RBD-S, is under development to prevent severe acute respiratory syndrome (SARS) caused by SARS coronavirus (SARS-CoV), which classified the US NIH as a category C pathogen. This vaccine comprised of recombinant receptor-binding domain (RBD) SARS-CoV spike (S) protein and formulated on alum, together with synthetic glucopyranosyl lipid A. The would induce neutralizing antibodies without causing Th2-type immunopathology. Vaccine being led nonprofit product partnership; Sabin Institute Texas Children’s Hospital Center for Development in collaboration two academic partners (the New York Blood University Medical Branch); an industrial partner (Immune Design Corporation); Walter Reed Army Research. roadmap RBD-S outlined goal manufacture clinical testing within next 5 years.
