On September 7, the New England Journal of Medicine (NEJM) published a study with troubling data. The study is a large observational study that looks at 887,193 children aged 5 to 11 years in North Carolina, of whom 273,157 (30.8%) received at least one dose of the Pfizer vaccine between November 1, 2021, and June 3, 2022. The study includes 193,346 children who had Covid-19 infections reported between March 11, 2020, and June 3, 2022. The researchers compared the effectiveness of the vaccines to the effectiveness of previous Covid-19 infections. They also compared the effectiveness of the vaccines when given to children that have had Covid-19. The results showed that infection from Covid-19 promotes better immunity in children than the vaccines. It also found that the immunity from the vaccines wanes quickly. Most disturbing, the vaccines appear to negate the immunity gained from infection even into negative territory. In other words, the vaccines sometimes promote Covid-19 infections. This is alarming.

Read MoreRandomized control trials (RCTs) have long been considered the gold standard for determining the effectiveness of a drug, surgery, or other medical intervention. But observational studies, although long regarded as second-rate compared to RCTs, have contributed invaluable information to the medical sciences. Indeed, analyses of RCTs compared to observational studies have concluded that well-run observational studies are comparable. I will explain RCTs and observational studies later in this post, but first, I want to tell the story of John Snow and how he used his powers of observation to lower worldwide death rates, perhaps more than anyone in history.
