Russia declares itself as the first country to approve a vaccine against the coronavirus. Scientists are skeptical

Russian President Vladimir Putin said Tuesday that a domestically developed coronavirus vaccine has been registered for use and has already been supplied to one of his daughters. 

At a government meeting, Putin said that the vaccine has proven effective during testing, offering long-lasting immunity against the coronavirus. Putin added that the vaccine underwent the necessary tests. 

Russian authorities have said that medical workers, teachers and other risk groups will be the first to be vaccinated.
