Here in Israel we are ahead of most other countries in terms of vaccination and the prevalence of the delta variant. After almost zero cases, the count is starting to creep up again. There is a lot of confusing data going around and it is surprising to me that the scientific community does not have a generic approach to evaluate the effectiveness of vaccines.

Last night the following table appeared on the TV news. Severe cases by age category and vaccination status. But these absolute numbers cannot be taken at face value.

“Open source” statisticians went to work and made some adjustments. The population categories are not equally big (there are more young people than old people), and the vaccination rate is not the same (older people vaccinate more). So the correct approach is to look at severe cases / million, split by vaccinated and unvaccinated. I put the results in the graph below and added the chart to the SlideMagic library.

I put the results in the graph below and added the chart to the SlideMagic library. Search for “vaccine’ in the SlideMagic app and the designs will pop up, either for use in a COVID-related presentation, or maybe something completely different that requires a similar layout.
