GSK plc GSK announced positive topline results from a phase III study evaluating the co-administration of its two marketed vaccines — RSV vaccine Arexvy and shingles vaccine Shingrix — in older adults (aged 50 years and older).

(Reuters) -British drugmaker GSK said on Wednesday administration of its respiratory syncytial virus (RSV) vaccine and shingles shot together generated the same immune response in a late-stage trial as separate adminstration of the vaccines.

In the study, co-administration of GSK's RSV vaccine Arexvy and shingles shot Shingrix elicited non-inferior immune responses compared with separate administration of the vaccines.

If approved, the co-administration of Arexvy and Shingrix could provide a more convenient vaccination regimen for patients and potentially bolster GSK’s faltering sales for both vaccines.

GSK plc (NYSE:GSK) released topline data from the phase 3 trial in adults 50 years and older evaluating the immunogenicity, reactogenicity and safety of Arexvy (Respiratory Syncytial Virus Vaccine) when co-administered with Shingrix (Zoster Vaccine).
