The race for a corona vaccine is not just a matter of saving lives it's also a matter of saving face for some world leaders.

And how can users trust the vaccine they're given? In a world brimming with disinformation seperating fact from fiction is challenging.
President Vladimir Putin says Russia is registering its third vaccine against the coronavirus and insists all of them are effective. But its Sputnik Five vaccine is still being trialled and there is no conclusive proof yet that it works.
