So in the table you've posted, it says "These data should be interpreted with caution. See information below in footnote about the correct interpretation of those figures"
And above the second table you've partially posted, it states, "Please note that the following table should be read in conjunction with pages 31 to 33 of this report, and the footnotes provided on page 39."
And then the footnotes, and those pages, explain, in precise and great detail, why "Comparing case rates among vaccinated and unvaccinated populations should not be used to estimate vaccine effectiveness against COVID-19 infection", and that "Vaccine effectiveness has been formally estimated from a number of different sources and is summarised on pages 5 to 14 in this report." They have links to articles -
https://ukhsa.blog.gov.uk/2021/11/02/transparency-and-data-ukhsas-vaccines-report/ - explaining why not to do what you're doing.
And yet, you've somehow missed all of that, and run full pelt into the
incorrect interpretation of those figures.
And that's the problem here. You're confusing your lack of reading comprehension with everyone else's. Maybe don't.
