A walk-up COVID-19 testing and vaccination clinic in Frank Ogawa Plaza in downtown Oakland reopened Thursday following an abrupt closure last week, city officials said.

The clinic at 250 Frank Ogawa Plaza is open until 5 p.m. Thursday offering free vaccinations and free, 24- to 48-hour testing. Starting Friday, it will be open from 9 a.m. to 5 p.m. Monday to Friday, including holidays.

The clinic, which is operated by Covid Clinic, closed last week due to staffing and vaccine shortages, according to the city.

“Amid the season of holiday travel and gatherings, coupled with the emergence of the omicron variant here in the East Bay, it is critical that Oaklanders have easy access to COVID vaccines, boosters, and rapid testing,” Oakland City Administrator Ed Reiskin said in a statement.

“I am pleased that Covid Clinic is providing these essential services to our community,” he said.

People may have to pay for rapid antigen and rapid antibody tests. Results for these tests are ready in 30 minutes.

The clinic in Frank Ogawa Plaza offers Pfizer, Johnson & Johnson and Moderna vaccines for adults. Vaccines for children are not being offered at the clinic, city officials said.

Covid Clinic is also operating another clinic in Oakland at 3411 E. 12th St., Suite 130, in the Fruitvale district.

The Fruitvale location is open Saturday through Wednesday from 9 a.m. to 5 p.m. It will be open Christmas Day from noon to 5 p.m. and New Years Day from 10 a.m. to 5 p.m. Thursday and Friday of this week, the Fruitvale clinic is closed. It will reopen Saturday at 9 a.m.
