Former FDA boss says he's 'concerned' about new COVID variant 'Pirola'

A former boss has said he is 'pretty concerned' about a new Covid strain already spreading in the US.

Dr Scott Gottlieb warned that was 'highly mutated' and therefore likely to be better at escaping the immune systems of vaccinated or previously infected people.

He acknowledged there is no evidence the variant is deadlier than older versions of the virus, but Covid fatalities in the US have already started to creep up, though they remain at near historic lows.
