The county’s first and largest vaccination super site at Petco Park will close Saturday as San Diego County public health officials reported 421 new COVID-19 infections and 13 deaths Friday.

The Petco Park site, which has provided more than 200,000 Moderna vaccines, has closed multiple times due to lack of vaccines, but with the Padres preparing for opening day, its closure was inevitable.

The county, the city, UC San Diego, and the Padres opened the superstation on Jan. 11. Five other superstations are operating in La Jolla, Chula Vista, La Mesa, San Marcos, and Del Mar, even as the last one faces supply issues of its own.

Scripps Health, which runs the Del Mar site, announced Friday the super station will be closed on March 27 and 28, due to the low number of COVID-19 vaccine doses delivered.

The San Diego County Health and Human Services Agency reported more than 761,000 — or 28.3% of San Diego County residents over the age of 16 — have received at least one dose of the two-shot vaccines and more than 480,000 people — or 17.9% — have been fully vaccinated.

Nearly 1.44 million COVID-19 vaccine doses have been delivered to the region and more than 1.36 million have been logged as administered. This number includes both county residents and those who work in San Diego County.

The latest statistics from the county bring the cumulative number of coronavirus cases to 267,177 and the death count to 3,491. Nine men and four women died between Jan. 6 and March 18.

The HHSA also reported 258 patients hospitalized with COVID-19 in San Diego County, unchanged from Thursday. Of that number, 91 were being treated in intensive care units, an increase of seven from the previous day.

Of 11,792 tests reported Friday, 4% returned positive. The 14-day rolling average is 2.8%.
