Great Variation in Counties’ COVID-19 Vaccine Distributions California has increased its immunization rate overall, but vaccine distribution still greatly varies between counties. Some have nearly one-third of their residents vaccinated, while others are at just 5 percent. Teri Sforza, The Orange County Register | February 11, 2021 | Analysis (TNS) — California is pushing shots into arms at a much faster clip than it was just a month ago — closing in on the national average, with vows to accelerate even further — but the pace of COVID-19 vaccinations varies greatly from county to county within the Golden State. A Southern California News Group analysis of state data found that smaller counties with fewer people and less complicated logistics are leading the pack in vaccinating their residents: Little Mono, with 14,526 residents, ranked No. 1, managing to vaccinate one out of every three residents. On its heels was tiny Alpine, population 1,209, getting shots into 27 percent of its residents.
