Interesting data on the age distribution of cases of the "Indian" coronavirus mutation in Britain come from June data collected by Public Health England: Among other things, it is clear that single-dose vaccination does not protect people over 50 from the disease, while on the contrary under the age of 50 there is a degree of protection of about 45%, despite the fact that this mutation "hits" mainly the younger ages.
The proportion of the British population over the age of 50 is 33.6%, while the proportion of those vaccinated, even with one dose of vaccine, is a total of 64% and in the case of those over 50, it reaches 91,4%, while in under 50, drops to 50,3%
As of June 21, there were 92.029 cases of Delta variant in Britain with 117 deaths, which means a mortality rate of 0,1%.
First remark: Only 10,5% of cases (9671 cases) are over 50 years old, when 33,6% of the British population belongs to this age group. However, it is not true that this under-representation is a result of the high percentage of vaccinated (91,4%) in this age group.
Second remark: The distribution of cases in those over 50 years of age between vaccinated and non-vaccinated is: 90% vaccinated and 10% unvaccinated. In short, "at least one dose" vaccination does not appear to reduce the chance of a person over the age of 50 becoming ill.
In contrast, in those under 50 years of age, the proportion of those vaccinated who became ill is clearly less than 50.3% of the proportion of those vaccinated in this group. Therefore, in those under 50 years of age, vaccination with "at least one dose" protects against disease by 45%, according to the latest available data.
Where there is a clear difference in the over 50s is in mortality,
which in the unvaccinated reaches 3.9% while in the vaccinated it is 0.8% and in the under 50s the numbers are already very small.
The Delta variant in the UK has spread mainly to younger ages - under 50 years. Vaccination as a whole in the UK, where the "first dose" policy is followed, provides only partial protection against the disease and that is why the incidence is high.
The low overall mortality is due to two factors: The first is the low mortality of the Delta variant in those under 50 years of age, regardless of vaccination, and secondly, the low penetration in people over 50 years of age, who are considered more vulnerable due to possible other health problems.
In this context, mortality is likely to increase, but not dramatically, as the vast majority of Britons over the age of 50 are vaccinated and the unvaccinated over the age of 50, which is the group with the highest mortality (3.9%), represent only 3% of the population…
