Official: L.A. County could hit COVID-19 herd immunity by end of July

If Los Angeles County continues to administer 400,000 COVID-19 vaccine shots a week, it will likely reach herd immunity among adults and older teenagers by mid- to late-July, Los Angeles County Public Health Director Barbara Ferrer said on Monday.

"The focus from here on in for us is to make it as easy as possible for eligible residents to get vaccinated," Ferrer told reporters during a news conference.

To reach herd immunity, a community must have enough people who have either been inoculated or have natural immunity to protect the rest of the population against the coronavirus. In Los Angeles County, more than 3 million people have received at least one dose of a COVID-19 vaccine, with 84 percent getting a second dose on schedule, 7 percent getting a second dose late, and 9 percent still waiting to get their second dose, the Los Angeles Times reports.

If 2 million more get their first doses, 80 percent of all residents 16 and older will have received at least one shot. Ferrer stressed that for the county to reach herd immunity in mid- to late-July, vaccine rates must stay steady. There are 750 vaccination sites across Los Angeles County, and mobile vaccination teams are visiting communities where people have mobility issues or there is a lack of health care facilities.

California has recovered from the surge in cases over the fall and winter, with the state now seeing its lowest hospitalization rate since the beginning of the pandemic.
