The cumulative efficacy over two seasons against RSV-LRTD was put at 67.2% and at 78.8% when it came to severe LRTD.

"Our goal is to provide a high level of protection for older adults most at risk from RSV," said Tony Wood, chief scientific officer at GSK.

"These data show the efficacy of a single dose of our vaccine over two RSV seasons against RSV-LRTD, including in the populations most at risk due to age or underlying medical conditions. This reinforces our confidence in its potential to make a significant public health impact."
