Abstract | Respiratory syncytial virus (RSV) is the leading cause of acute lower respiratory tract infections in children of <5 years of age worldwide, infecting the majority of infants in their first year of life. Despite the widespread impact of this virus, no vaccine is currently available. For more than 50 years, live attenuated vaccines (LAVs) have been shown to protect against other childhood viral infections, offering the advantage of presenting all viral proteins to the immune system for stimulation of both B and T cell responses and memory. The RSV LAV candidate described here, rgRSV-L(G1857A)-G(L208A), contains two modifications: an attenuating mutation in the |
