Marin health officials have launched a campaign to remove obstacles to getting a COVID-19 shot, the county's top public health officer said. We're in a full court press to reduce barriers to access to vaccines, Dr. Lisa Santora said Monday. As of Sept. 10, Marin was at the highest level of COVID-19 wastewater surveillance numbers since the summer surge of 2024, said Santora, citing data from the Marin County Department of Health and Human Services.
