Yesterday, Mr Putin announced that the vaccine had passed all the required checks, adding that his daughter had already been given it.
However, experts have a doubt on the speed of Russia's work and raise a big concern on its safety. The WHO urged Russia to follow a standard international guidelines for producing a vaccine against Covid 19.
Today, the WHO said it had been in talks with Russian authorities about undertaking a review of the vaccine that have not reached phase three clinical trials, and it is required more widespread testing in humans.
We reckon that an unsafe vaccine is just like a deadly drug! It does not help on saving lives but it may cause more losses.
