Check out Table 13b, titled "Covid deaths." Here are the facts:
From this three-week period in March, 4,067 people died of Covid, of which 3,647 received either their second or third dose of the vaccine more than 14 days prior. That comes out to 90.0% of all Covid deaths coming from fully-vaccinated people. However, according to the latest data from Johns Hopkins University, only 79.3% of the U.K.'s population has received even one dose (https://coronavirus.jhu.edu/vaccines/international), and according to the site Our World in Data, the percent who are fully-vaccinated is 75.4%.
Simple math tells us if the vaccines have efficacy, the percentage of the population dying from Covid has to be less than the percentage of the population that was vaccinated. That's not the case here. The percentage is actually greater, meaning (at least in the U.K.) a fully-vaccinated person is actually MORE likely to die from Covid than is an unvaccinated person.
Also, spare me the Reuters "fact" check. It is mathematically wrong, period, and besides that, it doesn't address the actual data. Finally, it's interesting that shortly after printing this damning data, the U.K. quit printing these tables in thier weekly surveillance reports. Gee, wonder why.
