Here is today’s COVID-19 update from the County Health and Human Services Agency with data through April 28.

Vaccination Progress:

  • More than 3.01 million COVID-19 vaccine doses have been delivered to the region, and over 2.69 million have been logged as administered. This number includes both County residents and those who work in San Diego County.
  • Overall, more than to 1.46 million County residents have received at least one dose of COVID-19 vaccine, including a single dose of Johnson & Johnson vaccine or the first dose of Moderna or Pfizer. That’s 54.4% of those eligible.
  • Of those vaccinated to date, over 1.02 million County residents, or 38.1% of San Diegans 16 and older, are fully immunized.
  • The goal is to fully vaccinate 75% of San Diego County residents 16 and older or 2,017,011 people. To date, 72.5% of the goal population has received at least one vaccine and 50.8% are fully vaccinated.
  • Veterans Affairs doses received and administered, as well as people vaccinated and fully vaccinated, are now included in the numbers and percentages above.
  • Those who received the one-dose Johnson & Johnson vaccine, which was approved for emergency use by the FDA April 23, 2021 following a pause to study adverse reactions in a small number of recipients, are being added to the total of fully vaccinated San Diegans.
  • The difference between doses shipped and the number of vaccinations administered represents approximately what is expected to be used 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 6.2 cases per 100,000 residents (as of April 27).
  • The County remains in the Orange Tier or Tier 3 under the state’s new guidance. The California Department of Public Health indicates that unless there are extenuating circumstances, such as low rate of vaccine uptake, a county will only move to a more restrictive tier if hospitalizations are increasing significantly among vulnerable individuals, especially among vaccinated individuals, and both testing positivity and adjusted case rates show a concerning increase in transmission. This is currently not the case in the region.
  • Currently, the testing positivity percentage is 2.3%, placing the County in Tier 3 or the Orange Tier.
  • The County’s health equity metric, which looks at the testing positivity for areas with the lowest healthy conditions, is 3.0% and is also in the Orange Tier or Tier 3.
  • CDPH assesses counties on a weekly basis. The next report is scheduled for Tuesday, May 4.

Community Setting Outbreaks:

  • One new community outbreak was confirmed April 28 in a daycare/preschool/childcare setting.
  • In the past seven days (April 22 through April 28), 19 community outbreaks were confirmed.

  • A community setting outbreak is defined as three or more COVID-19 cases in a setting and in people of different households over the past 14 days.
