Also mentions nothing at all about the rapidly-rising Delta strain that appears to hit younger people much harder than other/earlier strains and in preference to older folk. Ugh. This virus is horrible.
All strains affect younger people more than older ones. Because they aren't vaccinated.
I'd like to think that was accounted for in the analysis.
We can compare children infected last year when other strains were dominant, with children infected this year in UK (likely to get the Delta variant).
I'd also like to think that no one publishes garbage studies, but there we are.
