"It's great that San Diegans are getting their booster shots and that parents are vaccinating their children," said Dr. Wilma Wooten, county public health officer. "This will help to reduce the spread of COVID-19 as we enter the holiday season and into 2022.
"The more people who are vaccinated, the better off we'll be at putting this pandemic behind us," she said.
The county Health and Human Services Agency added the younger-children age group to the number of San Diegans eligible for the COVID-19 vaccine, increasing that number to 3,147,936.
"As a result, the percentages of San Diegans who have received at least one dose of the COVID-19 vaccine and of those who are fully vaccinated dropped by about nine percentage points each compared to last week," an HHSA statement read.
The number of county residents who have received at least one shot of a COVID-19 vaccine is now nearly 2.57 million -- or 81.7% of residents 5 and older. More than 2.32 million, or 73.8% of that cohort, are fully vaccinated.
