"New figures have been released which reveal how many coronavirus patients in Welsh hospitals have been vaccinated.
Data from Public Health Wales shows that of the 614 people in hospital with Covid on September 21
a total of 80.3% (493) of them were double-jabbed,
4.2% (26) had received one jab, and
12.9% (79) were unvaccinated.
Of the 470 coronavirus inpatients aged 60 and over
90% had been given both vaccine doses,
2.6% one dose, and
7% were unvaccinated.
Of the 144 patients under 60 with Covid
48.6% had been double-jabbed,
9.7% had received one dose, and
31.9% were unvaccinated.
As a significant majority of adults in Wales have now received two doses of the Covid vaccine experts said it is “to be expected” that a significant proportion of people in hospital will be fully vaccinated.
However the data clearly demonstrates that people are far more likely to wind up in hospital should they have received no jab at all.
[That may be so but the picture is complicated by the unvaccinated being tested much more often (eg upon admission for something else), and by so many hospitalizations with Covid being actually for something else.]
Public Health Wales has explained this by comparing the rate of hospitalisation in vaccinated and unvaccinated people per 100,000 population – similar to the seven-day Covid infection rate reported each day.
In the four-week period between August 23 and September 19 the Covid hospital admissions per 100,000 people was
32 in fully-vaccinated people and
53 in unvaccinated people.
[It would be interesting to see what is their rate
of all hospital admissions, whether for Covid or not.]
In the over-60s, where people are far more likely to need hospital treatment, the Covid hospital admissions per 100,000 was
63 in fully-vaccinated people and
121 in unvaccinated.
This means that if you are unvaccinated and in this age group you’re twice as likely to need a hospital admission. [So that’s just a 50% reduction.]
Dr Chris Williams, consultant epidemiologist for Public Health Wales, said: “The best way to understand vaccine effectiveness is to look at population level studies and not at hospital data.
“The incidence of hospitalisation is around two-thirds lower in vaccinated under-60s compared to unvaccinated and about 40% lower in vaccinated over-60s than unvaccinated.”
