Lassen County Last in State Vacc’s…California isn’t Close Yet to Herd Immunity


About two-thirds of eligible residents have received at least one dose of the vaccine. And as the governor likes to remind us, California has administered almost 16 million more doses than the next most populous state, Texas.

State health officials don’t set a vaccination goal for herd or community immunity, since children under 12 15% of the population cannot yet be vaccinated and previously infected people may already be protected.

But experts say that 70% to 85% of the total population must be fully vaccinated to reach large-scale protection against the virus.

The state tracks vaccination progress for those eligible by county. As of last week, Marin County led with 75% vaccinated among its 12 and older population. Lassen County ranked last with 22%. The top six counties with the highest percentage of vaccinated populations are in the Bay Area.
