The region has reached a milestone in the ongoing battle against the coronavirus, as the Los Angeles County Department of Public Health this week announced that more than 15 million vaccine doses have been administered. Still, an uptick in cases and worries about the Omicron variant have health and political leaders continuing to push vaccinations for all, and boosters for those who are eligible. On Thursday, the department announced 12 new cases of Omicron, bringing the countywide total to 30.


With the Vaccine Tracker, Crosstown is staying up to date on the latest and most important data on infections and inoculations.


More jabs

Whether it is the persistent messaging or work-related mandates to get a jab or lose a job, vaccinations are increasing. In the most recent week, 399,538 doses—including 86,987 second shots—were administered, a 33.5% increase from the previous week. 


As of Dec. 12 (the most recent day for which data is available), 167,327 doses had been given to children ages 5-11, representing 18.6% of county residents in the age range. According to the Public Health department, nearly 90,000 kids in this group have received two shots.

As of Dec. 12, a total 15,369,046 doses had been administered in the county, including 6,110,475 second doses. More than 7.4 million county residents have received at least one shot. An estimated 1.82 million booster doses have gone into arms. Yet despite all the progress, county health leaders said Monday that more than 2.2 million eligible area residents have not received even a single vaccination. 


More women than men continue to take the jab. According to Department of Public Health data, 79.7% of the more than 4.9 million females ages 5 and up in the county have received at least one dose. This compares with 75.2% of the 4.8 million eligible males.
