The sheer numbers of people vaccinated - nearly 95% of those over 60 and 84% of those under 60 - mean that statistically, double-vaccinated people will still be a significant proportion of hospital patients.

But, without the vaccine, those hospital numbers might be even higher.

Last winter, when Covid cases in the community were similarly high but the vaccine programme had only just started, there were four times as many Covid patients in hospitals in Wales.
