RSV Prefusion F Immunoglobulin G-Derived Protection Begins To Wane Six Months After Infection, Study Finds

Infectious Disease Advisor (6/27, Nye) reported a study found that “protection conferred by respiratory syncytial virus (RSV) prefusion F (preF) immunoglobulin (Ig)G antibodies wanes 6 months after infection or disease exposure.” Researchers added that “as RSV prefusion immunoglobulin G-derived protection begins to wane 6 months after infection, preventive measures should be timed appropriately in high-risk patients to ensure reduced disease risk throughout an RSV season.” The study was published in The Journal of Infectious Diseases.
