Five California counties have both a higher percentage of their eligible residents fully vaccinated and a higher average daily case rate than the statewide average: Los Angeles, San Diego, Alameda, Contra Costa and San Francisco. The five counties with falling case rates — Modoc, Glenn, Lassen, Del Norte, San Benito — have below-average vaccination rates.
It is difficult to draw conclusions from just this report. Many of the most vaccinated counties are also among the densest. It would seem that the best strategy is to live in a low density area.
