Well Tricky has a point:

In 2016 there was the first ever reported death anywhere in the world (in India) due to a meteorite strike.

Between 1987 and 2016 there were 58 fatalities due to being struck by lightning in the UK alone, globally there were an average of over 4,000 pa in 2016

On the other hand in the full period from 1900 to 2016 there were no reported global deaths from Covid 19

So clearly, during a thunder storm, your best place of refuge is on a Covid 19 ICU wearing no PPE.
