The latest numbers from the UK reveal the Covid infection rates among the vaccinated now exceed the unvaxxed in every age group over 30.
The data is from the report “COVID-19 vaccine surveillance report – Week 40” of UK Health Security Agency.
Following is vaccination status of COVID-19 cases, deaths and hospitalisations by week of specimen date
over the past 4 weeks up to week 39 (up to 3 October 2021).
The report noted:
The rate of a positive COVID-19 test varies by age and vaccination status. The rate of a positive
COVID-19 test is substantially lower in vaccinated individuals compared to unvaccinated
individuals up to the age of 39. In individuals aged greater than 40, the rate of a positive
COVID-19 test is higher in vaccinated individuals compared to unvaccinated. This is likely to be
due to a variety of reasons, including differences in the population of vaccinated and
unvaccinated people as well as differences in testing patterns.
However, the report explained:
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. This is especially true because vaccination
has been prioritised in individuals who are more susceptible or more at risk of severe disease.
Individuals in risk groups may also be more at risk of hospitalisation or death due to nonCOVID-19 causes, and thus may be hospitalised or die with COVID-19 rather than because of
The report added:
The rate of hospitalisation within 28 days of a positive COVID-19 test increases with age, and is
substantially greater in unvaccinated individuals compared to vaccinated individuals.
The rate of death within 28 days or within 60 days of a positive COVID-19 test increases with
age, and again is substantially greater in unvaccinated individuals compared to fully vaccinated
The report concluded:
Several studies of vaccine effectiveness have been conducted in the UK which indicate that 2
doses of vaccine are between 65 and 95% effective at preventing symptomatic disease with
COVID-19 with the Delta variant, with higher levels of protection against severe disease
including hospitalisation and death. There is some evidence of waning of protection against
infection and symptomatic disease over time, though protection against severe disease remains
high in most groups at least 5 months after the second dose.
