Here is a surprising analysis published in the Expose.uk, arguing that based upon data from the UK Health Security Agency, which has recently replaced Public Health England, that the Covid-19 vaccines have an average negative effectiveness in everyone over the age of 18 in the UK of minus-seventy-three-percent! How can this be so? Well, as with any statistical argument, it is difficult to give a summary in a few lines, but those interested in figures can work through the data and calculations below. In short, with corrected data, they go through the same calculations that Pfizer originally did to claim its 95 percent effectiveness (relative effectiveness rather than absolute effectiveness anyway) rate, and get the negative figure.
