Good Morning Britain discussed the news that Russia's health ministry has given regulatory approval for the world's first coronavirus vaccine, on Wednesday's show.
Amid claims the UK are "likely to reject" the vaccine, GMB's doctor Sarah Jarvis had her say on the apparent breakthrough. But she was not impressed at all, suggesting not all steps had been taken ahead of the potential rolling out of the Covid-19 vaccine, dubbed Sputnik V.
Russia's President Vladimir Putin vowed the vaccine is safe as he announced Russia can expect a mass jab roll-out. But Dr Sarah wasn't on-side with this at all, telling GMB hosts Kate Garraway and Adil Ray that it was "unacceptable" if it wasn't safe.
