Vaccines for the general public will be available through pharmacies (e.g., Safeway, CVS, Walgreens, RiteAid) and local healthcare providers (e.g, Kaiser).


Know your COVID-19 Community Level

The CDC’s COVID-19 Community Levels are a tool to help communities decide what prevention steps to take based on the latest data. Levels can be low, medium, or high and are determined by looking at hospital beds being used, hospital admissions, and the total number of new COVID-19 cases in an area. Take precautions to protect yourself and others from COVID-19 based on the COVID-19 Community Level in Marin or other community in which you live, work or visit.
