I took a look at the latest Covid-19 daily deaths in English hospitals statistics, available to download from the NHS website here: https://www.england.nhs.uk/statistics/statistical-work-areas/covid-19-daily-deaths/. They include a weekly breakdown by age of those who have lost their lives after testing positive for coronavirus.
The Excel chart above shows the number in each age-group who died with Covid-19 per week through the pandemic. looking closely at the right hand side of the chart, the number of 80+ deaths appears to be falling at a faster rate than the number of deaths for the other age groups….probably because the vaccination programme saw them being vaccinated before the younger age groups.
Looking next at the percentage of Covid deaths in English hospitals which were of those aged 80+, the pattern is confirmed. The chart below shows this percentage for all weeks during which 200 or more people died with Covid; the green columns showing the 10 weeks in which the 80+ age group deaths were their lowest percentage of the total. The red labels show the number of 80+ year old people who died during those weeks.
By now (late March 2021), the majority of the 60-79 age group have had at least one dose of coronavirus vaccine, but very few of the 40-59 age group have.
The chart below shows the percentage of all English hospital Covid deaths that were from the age group 40-59 (for weeks with >200 total Covid deaths). The 10 weeks in which this percentage was at its highest are highlighted in red, with the red labels showing the number of deaths in those weeks.
The chart clearly shows that the proportion of Covid deaths in English hospitals for those aged 40-59 has increased consistently since the start of the vaccination programme in the New Year (which resulted in fewer people in the older age groups succumbing to the virus).
