Russia on Tuesday became the first country to officially register a coronavirus vaccine and declare it ready for use, despite international skepticism. President Vladimir Putin said that one of his daughters has already been inoculated.
Putin emphasized that the vaccine underwent the necessary tests and has proven efficient, offering a lasting immunity from the coronavirus. However, scientists at home and abroad have been sounding the alarm that the rush to start using the vaccine before Phase 3 trials — which normally last for months and involve thousands of people — could backfire.
