Still doesn't provide a full explanation for the trend we're seeing.
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.
Not sure about the proportions there, going by your figures:
Unvaccinated: 77% of the 297 hospital admission on 24 Sept means 229 cases, 78% of 375 on 28 Sept is 292. A 27% rise.
Vaccinated: 4% of the 297 hospital admissions on 24 Sept means 12 cases, 5% of the 375 on 28 Sept is 19. A 58% rise.
I would think the number of vaccinated cases is going to rise and fall by greater proportions while the numbers are low, but they will rise over time as a higher proportion of the population are vaccinated and there are more break through infections, some leading to hospitalisation.
More data will surely make this clearer. I am not convinced a trend is much use for vaccinated cases with such small numbers. More time helps with small numbers as we can smooth out the trend. Given the numbers in terms of vaccinated people being hospitalised just one more case is a 5% rise so we would need larger numbers or more days of data to see what is happening.
Given that almost 50% of the 16+ population is vaccinated, and that you are far more likely to be hospitalised if you are older (disease has more impact on older people) and the older groups in the population have higher vaccination rates, the fact that only 5% of hospitalised patients are vaccinated leads me to conclude the vaccines are keeping people out of hospital.
