Russia's Sputnik V COVID-19 vaccine equally effective for all age groups: Developer

The Russian-made Sputnik V coronavirus vaccine has proven equally effective for all age groups, Alexander Gintsburg, the head of the Gamaleya research institute that developed the vaccine, said on Saturday. "Sputnik V demonstrated the same level of efficacy in all age groups. At first, there were doubts that the efficacy in people aged 60 and over would be lower ... but it was absolutely not," Gintsburg told the SolovyovLive show on YouTube.
