Tony Wood, chief scientific officer at GSK, added in a press release, “We are pleased with ACIP's recommendation to expand the benefits of RSV [immunization] to more than 13 million adults aged 50-59 who are at increased risk for the severe consequences of this virus.”4
The ACIP also voted unanimously to recommend that GSK's pentavalent MenABCWY
