More than a million doses of the COVID-19 vaccines have been administered in the region, the County Health and Human Services Agency reported today.

Of those vaccinated to date, more than 319,000, or nearly 12 percent of San Diegans 16 and older, are fully immunized. A total of 619,924 people, or 23.1 percent, have received at least one dose of the two-dose regimen.

“We are making great progress in vaccinating San Diegans but it is too soon to let our guard down,” said Wilma J. Wooten, M.D., M.P.H., County public health officer. “Herd immunity does not occur until at least 70 percent of the population 16 and older is fully vaccinated and we have a ways to go before we can get back to many of the things we miss.”

The region’s vaccination efforts are slowed by shortages in vaccine supply, forcing several vaccination sites across the region to pause.

The following sites will be paused through Monday: the Lemon Grove Community Center, the Central Region Immunization Clinic in Logan Heights, the Copley-Price YMCA in City Heights, the Martin Luther King Community Center in National City, the Border View YMCA in Otay Mesa and the Linda Rhoades Recreation Center in Vista. The North Coastal Live Well Center in Oceanside is closed but will open Monday for second doses. Additional information about the temporary closures of the vaccination sites can be accessed here.

Vaccination Progress:

  • Of the 1.1 million COVID-19 vaccine doses delivered to the region, more than 1,026,000 have been logged as administered. Of those vaccinated to date, more than 319,000, or nearly 12 percent of San Diegans 16 and older, are fully immunized.
  • Overall, more than 619,000 County residents have received at least one shot of two-dose vaccine. That’s 23.1 percent of those eligible.
  • The difference between doses delivered and those used in a vaccination represents approximately what is expected to be administered in the next seven days and doses still to be entered in the record system.

State Metrics:

  • San Diego County’s state-calculated, adjusted case rate is currently 10.8 cases per 100,000 residents (as of March 2) and the region is in Purple Tier or Tier 1.
  • The testing positivity percentage is 4.2%, placing the County in Tier 3 or the Orange Tier. While the testing positivity rate for the County qualifies it for Tier 3, the state uses the most restrictive metric – in this case the adjusted case rate – and assigns counties to that tier. Therefore, the County remains in the Purple Tier or Tier 1.
  • The County’s health equity metric, which looks at the testing positivity for areas with the lowest healthy conditions, is 6% and is in the Red Tier or Tier 2. This metric does not move counties to more restrictive tiers but is required to advance to a less restrictive tier.
  • The California Department of Public Health assesses counties on a weekly basis. The next report is scheduled for Tuesday, March. 9.

Community Setting Outbreaks:

  • Four new community outbreaks were confirmed March 4: two in daycare/preschool/childcare settings, one in a business setting and one in a preschool setting.

  • The 14-day rolling average percentage of positive cases is 3.4%. Target is less than 8.0%.
  • The 7-day, daily average of tests is 12,628.
