Overview
**GSK3844766A + AS01E** is a combination vaccine candidate for the prevention of moderate-to-severe lower respiratory tract disease (LRTD) caused by respiratory syncytial virus (RSV) in older adults[3][5][7]. The drug consists of the RSVPreF3 recombinant antigen (GSK3844766A) formulated with GSK’s proprietary AS01E adjuvant system to enhance the immune response in this population, which typically exhibits weaker immunity to vaccination. The vaccine is administered intramuscularly and has undergone Phase I/II clinical evaluation. Immunization stimulates robust neutralizing antibody and cellular responses against RSV, with AS01E boosting both magnitude and duration of immunity[3][4][5][7].
