GSK Wins Positive EU Opinion on Bexsero Booster
GSK plc announced that the European Medicines Agency's CHMP recommended adding a single booster dose for its MenB vaccine, Bexsero, for people aged 10 and older. The recommendation is based on a Phase IIIb trial showing a stronger immune response in previously vaccinated individuals. GSK shares were up 0.79% at 1,916p.
