So, what are the results? There were 139 AESIs among the 33,986 people vaccinated, one for every 244 people. That may sound bad, but those numbers mean nothing without comparison against a control group. There were 97 AESIs among the 33,951 people who received a placebo. Combining these numbers implies 12.5 vaccine-induced AESIs for every 10,000 people vaccinated, with a 95% confidence interval of 2.1 to 22.9 per 10,000 people. To phrase it differently, there is one additional AESI for every 800 people vaccinated (95% CI: 437-4762).
That is very high for a vaccine. No other vaccine on the market comes close.
