GSK RSV vaccine Arexvy accepted for regulatory review by EMA to expand use in adults 18 years, older

RSV is a common contagious virus affecting the lungs and breathing passages and impacts an estimated 64 million people of all ages globally every year. RSV can exacerbate certain medical conditions, and lead to severe illness resulting in hospitalisation and even death.

A European regulatory decision on this submission is anticipated in H1 2026. GSK is continuing to seek expanded indications for its RSV vaccine in other geographies including the US and Japan.

Respiratory Syncytial Virus Vaccine, Adjuvanted, contains recombinant RSV glycoprotein F stabilised in the prefusion conformation (RSVPreF3). This antigen is combined with GSK’s proprietary AS01E adjuvant.

The use of this vaccine should be in accordance with official recommendations. As with any vaccine, a protective immune response may not be elicited in all vaccinees.

The vaccine has been approved for the prevention of RSV-LRTD in individuals 60 years of age and older in more than 60 countries. In addition, it is approved for use in individuals aged 50-59 who are at increased risk due to certain underlying medical conditions in more than 50 markets, including the US, Japan and Europe.

The GSK proprietary AS01 adjuvant system contains STIMULON QS-21 adjuvant licensed from Antigenics Inc, a wholly owned subsidiary of Agenus Inc. STIMULON is a trademark of SaponiQx Inc., a subsidiary of Agenus.
