The bulk of the article isn't my issue, it's the clickbait headline designed to get retards like yourself riled up over literally nothing. In
that post you point out that Delta variant infections in the over 50s, who have been vaccinated with 1 dose outnumber the people who haven't been vaccinated
"9 to 1". Which makes sense, as ~91% of people in the UK who are over 50
have been vaccinated. Back in April, nonetheless.
The table that you linked showed the vaccinated who are over 50 are 2.5x more likely to be in emergency care with the Delta variant. What you fail to do is put that into perspective and realize that again, ~91% of over 50s are already vaccinated. If the vaccine was ineffective/made things worse as you seem to be implying, you would get a number that is closer to 9x. It isn't though, because the vaccine is effective at preventing the majority of disease caused by the infection.
Are you capable of understanding those simple numbers? Scientists aren't "trying to figure out why" as anybody with the ability to add, subtract, multiply and divide is capable of realizing it's literally nothing. Are you also actually so retarded you think 5G is dangerous too?
