Chris asked for the link, and here it is. Scroll to page 44, and you will find 2,084 died from Covid for the first three weeks in March, of which only 202 (9.7%) Were vaccinated.
The report states, "In the context of very high vaccine coverage in the population, even with a highly effective vaccine, it is expected that a large proportion of cases, hospitalisations and deaths would occur in vaccinated individuals, simply because a larger proportion of the population are vaccinated than unvaccinated and no vaccine is 100% effective." However, the problem with that is that over 90% of the Covid deaths were among the vaccinated, yet only 73% of the population were vaccinated as of March 20.
