President Vladimir Putin said on Tuesday that Russia had become the first country in the world to grant regulatory approval to a coronavirus vaccine after less than two months of human testing, a move hailed by Moscow as evidence of its scientific prowess. He added that his daughter has been vaccinated. The development paves the way for the mass inoculation of the Russian population, even as the final stage of clinical trials to test safety and efficacy continues. The speed at which Russia is moving to roll out its vaccine highlights its determination to win the global race for an effective product but has stirred concerns that it may be putting national prestige before sound science and safety. Speaking at a government meeting on state television, Putin said the vaccine, developed by Moscow’s Gamaleya Institute, was safe and that it had even been administered to one of his daughters. “I know that it works quite effectively, forms strong immunity, and I repeat, it has passed all the needed checks,” said Putin. He said he hoped the country would soon start mass-producing the vaccine.
