Harvard Medical School Professor Martin Kulldorff says the Delta variant of COVID-19 is “not a gamechanger” or a mutation we should be “specifically concerned about”.
“A virus will always mutate, there will always be different variants – that’s not strange,” Professor Kulldorff told Sky News.
“Sometimes we get variants that are a little bit more infectious or that spreads a little bit more easily. But the key thing is that the delta variant is the same in terms of, it affects older people but not younger people.
“So, if you suddenly get mutations where younger people start dying. But that’s not the Delta variant.
“It’s not a gamechanger, and it’s nothing we should be specifically concerned about.”
