GSK Sues Pfizer for Alleged Patent Infringement Over RSV Vaccine

GSK has sued Pfizer in a US court, alleging infringement of the patents it holds on vaccines for respiratory syncytial virus (RSV).

The lawsuit claims that Pfizer’s Abrysvo infringes on four of GSK’s patents that cover its rival vaccine, Arexvy.

In May, Arexvy became the first RSV vaccine to be approved anywhere in the world after it received approval from the US Food and Drug Administration (FDA). The US approval of Pfizer’s vaccine followed shortly afterwards.
