Remember that hospitalizations take at least 2-3 weeks post infection to occur, and that you don’t see protection from the first dose for at least five days or so. So you’d expect hospitalizations to lag 18-26 days or so. Also the chart is not saying all those groups had vaccines: those under 60 largely haven’t been. The labels could have been clearer. It’s just a chart of change in hospitalization by age from a starting date.

You are saying "Late vaccinated 0-59 years old" should be read as "Unvaccinated and late vaccinated 0-59 years old"? Why didn't they use that label then?

  Because they have been vaccinated. The vaccine just (likely) hasn't taken affect and started affecting the statistics yet.

    I'm not sure that is true. As I understand it, it's a cohort of people of that age who live in a geographical area of Israel where vaccination was started early. So it includes people of that age who declined the vaccine/didn't get it fr other reasons. Of course, you're also correct that another important factor is that some of the cohort are not yet fully protected. The definitions are here: https://www.medrxiv.org/content/10.1101/2021.02.08.21251325v1 https://www.medrxiv.org/content/10.1101/2021.02.08.21251325v...

      Yeah I was wrong. I believe early and late refers to cities and the cohorts are taken from early or late cities.

  Actually, I was wrong. I checked the source paper. I believe the labels refer to cohorts from cities that were early in the vaccination campaign vs cohorts from cities that were late in the campaign. So 0-59 late vaccinated means some vaccines but later in time and fewer in number. This is what I gathered from the abstract anyway: https://www.medrxiv.org/content/10.1101/2021.02.08.21251325v1 https://www.medrxiv.org/content/10.1101/2021.02.08.21251325v...
