On July 15, 2021, the County of Los Angeles Department of Public Health, through its Health Officer Dr. Muntu Davis, announced that the County would reinstate its indoor mask mandate effective 11:59 p.m. on Saturday, July 17, 2021, in response to a reported rise in the Delta variant of the COVID-19 strain across the County. In doing so, Dr. Davis made clear that the order will apply to everyone, regardless of COVID-19 vaccination status, noting that “we’re not where we need to be for the millions at risk of infection here.”
Yet the CDC and the County both recognize vaccinated individuals’ risk of either infection or transmission is extremely low. Further, the County vaccinations are less than ten percentage points below the benchmark that experts consider herd immunity. In short, the County has no rational basis and no authority for the Health Officer Order.
