GlaxoSmithKline CEO Emma Walmsley on Wednesday said she expects uptake for the company's new RSV vaccine to start off slower than it did for its blockbuster shingles shot.
Last month, GSK's RSV shot became the first to win approval in the U.S. and European Union for the treatment of adults 60 and above.
The company has not provided estimates for how much revenue the RSV shot will rake in this year following its launch.
GSK's vaccine against shingles, a viral infection that causes a painful rash, is the company's top-selling drug.
Investors are hoping that Shingrix and GSK's RSV shot will help offset patent expirations for some of the company's blockbuster HIV drugs in a few years.
