"When we look at data from hospitals, so patients who are in hospital with the virus, the outcomes for those with the original virus or the new variant look the same, so there's no real evidence of an increase in mortality for those in hospital," he said.

For a man in his 60s, Vallance explained, the average risk with the old variant would be that for every 1,000 people infected, roughly 10 would die from COVID-19. For the new U.K. variant, he said, roughly 13 or 14 people might be expected to pass away.
"And you will see that across the different age groups as well, a similar sort of relative increase in the risk."
The newer variant started spreading through the U.K. in the fall and has now been identified inas well. So far, research indicates that the current against the U.K. variant.
