1170 vaccinations to prevent 1 severe COVID-19 case , vs 1.2 vaccinations to prevent 1 case of Measles

BMJ rapid response - Nov 2020

"So to prevent one severe illness 1370 individuals must be vaccinated. The other 1369 individuals are not saved from a severe illness, but are subject to vaccine adverse effects, whatever they may be and whenever we learn about them."

"How does this compare with other vaccines? Before the measles vaccine became available 90% of children in North America had measles by age 10. Two doses of the vaccine are about 95% effective, so a vaccinated individual’s risk is reduced by 0.855 (0.90 x 0.95), and the NNTV = 1.17 (1/0.855); this is extraordinarily effective"
