RSV is a major cause of severe respiratory illness in older people and can lead to disability and death. There is a serious unmet medical need for an effective vaccine that can help protect the elderly from this highly infectious disease. Pfizer (PFE) declared the start of a clinical trial RENOIR, a Phase 3 clinical trial evaluating the efficacy, immunogenicity, and safety of a single dose of its respiratory syncytial virus (RSV), a bivalent perfusion F-subunit vaccine candidate (RSVpreF) in adults 60 years or older. The beginning of the Phase 3 study is an important step towards the goal of a comprehensive immunization against RSV.
