From the article: Various health economists have calculated a NNTV for COVID-19 vaccines. Ronald Brown, a health economist in Canada, estimated that the NNTV to prevent a single case of coronavirus is from 88 to 142. Others have calculated the NNTV to prevent a single case at 256. German and Dutch researchers, using a large (500k) data set from a field study in Israel calculated an NNTV between 200 and 700 to prevent one case of COVID-19 for the mRNA shot marketed by Pfizer. They went further and figured out that the “NNTV to prevent one death is between 9,000 and 100,000 (95% confidence interval), with 16,000 as a point estimate.” ..... Furthermore, the NNTV to prevent a single case is not a very meaningful measure because most people, particularly children, recover on their own (or even more quickly with ivermectin if treated early). The numbers that health policy makers should really want to know are the NNTV to prevent a single hospitalization, ICU admission, or death. But with the NNTV to prevent a single case already so high, and with significant adverse events from coronavirus vaccines averaging about 15% nationwide, Pharma and the FDA dare not calculate an NNTV for hospitalizations, ICU, and deaths, because then no one would ever take this product (bye bye $93 billion in annual revenue). - https://en.wikipedia.org/wiki/Number_needed_to_treat https://en.wikipedia.org/wiki/Number_needed_to_treat
