"Is San Francisco on the verge of a herd immunity breakthrough? Experts are optimistic
...Over the past seven days, San Francisco, home to more than 870,000 people, recorded an average of only 26 new Covid-19 cases per day. Two-thirds of all adults in San Francisco and almost 60 percent of the greater metro area of 4.7 million have been vaccinated with at least one dose — one of the highest rates in the U.S. Its positive test rate sits at 1.2 percent.
...San Francisco had the advantage of ramping up its vaccination campaign while cases, hospitalizations and daily deaths were already relatively low, which most likely accounts for much of the city’s success so far. This past winter, when much of the country was battling a devastating surge, San Francisco’s cases peaked on Jan. 4 with 560 reported infections. By comparison, Los Angeles recorded its peak on Dec. 26, with more than 29,000 new cases.
