Still doesn't provide a full explanation for the trend we're seeing.On August 13 I posted a link to an article explaining the fact that as most people become vaccinated there will be more people dying who are vaccinated than who are not vaccinated.
In the past four days, the percentage of double-vaxxed people hospitalised has risen by 52%
In the past four days, the percentage of unvaxxed people hospitalised has risen by 47%
Comparable but I would expect the percentage of double-vaxxed to rise much more slowly given two doses means you're 96% less likely to be hospitalised.
Perhaps it has something to do with the very small numbers involved with respect to the total populations (1.05m unvaxxed, 2.62m double-vaxxed). Will revisit when there's more data available.
