Karl Friston: up to 80% not even susceptible to Covid-19

Just one month ago, the idea that most people aren’t susceptible to Covid-19 — perhaps the overwhelming majority — was considered dangerous denialism. It was startling when Nobel-prize-winning scientist Michael Levitt argued in UnHerd at the start of May that the growth curves of the disease were never truly exponential, suggesting that some sort of “prior immunity” must be kicking in very early.

Today, though, the presence of some level of prior resistance and immunity to Covid-19 is fast becoming accepted scientific fact. Results have just been published of a study suggesting that 40%-60% of people who have not been exposed to coronavirus have resistance at the T-cell level from other similar coronaviruses like the common cold.

Now, from the unlikely source of a prominent member of the “Independent SAGE committee”, the group set up by Sir David King to challenge government scientific advice and accused by some of being populated with Left-wing activists, comes a claim that the true portion of people who are not even susceptible to Covid-19 may be as high as 80%.
