This is one of the better analyses of the issue of naturally-acquired vs vaccine-induced immunity that I’ve come across.
There were several studies that he did not cite, but many of those come to similar conclusions to the ones in this presentation and many are regarding cellular immunity. His conclusions are spot-on.
I would only add that I think he is being too gracious when he says U.S. CDC position is simply a utilitarian approach designed to be simplest way to get as many people to immunity as possible (population focused) while the U.K. approach uses a more individual medicine approach that acknowledges natural immunity as protective for at LEAST 6 months.
He does acknowledge clearly that natural immunity is superior, based on the data, compared to vaccine-only immunity; at least to the extent to which we can study the phenomenon to date.
