We waiting REAL WORLD DATA.
Health authorities in various countries should look into the "population vaccination rates" of event clusters and publish them. It *MUST*
Eg. Outbreak of the delta in Massachusetts was VE *negative* calculated based on the vaccination rate of the Massachusetts citizens at the time.
479 people were infected, of which 346 were vaccinated. The vaccination rate in this population was 69%.
Now, when calculated for the Omicron, things are even worse. Hell.
For the 43 cases of Omicron infection reported by the CDC, i used averages for the entire U.S. because we did not know the vaccination and booster rates of the cluster population.
