As of Thursday, the city of Los Angeles had vaccinated 152,612 people against COVID-19 at five city-run vaccination sites. The problem, Los Angeles Mayor Eric Garcetti said, is supply. The city needs more vaccines.

Though California has said eligibility may go by age, Garcetti asked for flexibility Thursday so the city can get vaccines into communities where people are disproportionately dying -- specifically communities of color.

"The next group designated to be moved into receiving the vaccines in the coming weeks will be our workers in emergency services, as well as food and education and child care," Garcetti said.

The city has increased vaccine rollout by 17% since last week, Garcetti said, and its Dodger Stadium site is vaccinating 12,000 people per day. The entire county received 137,000 doses this week and expects 188,000 next week, according to Los Angeles County Public Health Director Dr. Barbara Ferrer.

"The city has distributed 81% of the doses that we have received," the mayor said. "This number is among the highest in the country, higher than many of our peer cities."

COVID-19 stats continue to improve in the hardest-hit county in America. Hospitalizations were down 3% and cases were down 3.4% from Wednesday, Garcetti said. However, Los Angeles County still reported 273 deaths from the disease on Thursday, crossing 16,000 total.

Tampa Mayor Jane Castor signed an executive order Thursday requiring the use of face coverings at outdoor Super Bowl-related activities to help mitigate the spread of COVID-19 in the Florida city.

The order targets sites where large crowds of people are likely to congregate around the Super Bowl this weekend, with limited ability to remain socially distant from each other. They include "Event Zones" in areas of downtown Tampa and surrounding Raymond James Stadium, as well as "Entertainment Districts," including Ybor City Historic District, the South Howard Commercial Overlay District, the Central Business District and the Channel District.

Those exempt from the order include children under the age of 5, someone communicating with a hearing-impaired individual and people with existing health conditions who would be impaired by a mask.

The Super Bowl will be held on Feb. 7 between the Kansas City Chiefs and hometown Tampa Bay Buccaneers. The mask mandate is in effect now through Feb. 13. Those who violate it could be subject to a $500 fine.

The NFL had previously announced that masks will be required in the stadium unless eating or drinking.

Under a previous order still in effect, masks are required in Tampa at indoor locations outside the home when social distancing cannot be maintained.

California had its second-deadliest day of the coronavirus pandemic on Wednesday, with 737 additional fatalities from COVID-19.

The deadliest day was Jan. 21 when 764 deaths from the disease were recorded, according to data from the California Department of Public Health.

This comes as the daily number of new COVID-19 cases has dropped considerably in the Golden State.

California's seven-day positivity rate for COVID-19 tests currently stands at 7.9%.

The U.S. Department of Health and Human Services has amended rules on who can administer COVID-19 vaccines to address potential shortages.

Any retired nurse or doctor whose license expired in the past five years can now be brought back to give the shot, and anyone licensed or certified to give a COVID-19 vaccine in their state can do so in other states.

The official commemoration of the 76th anniversary of Auschwitz's liberation will be held online Wednesday due to the coronavirus pandemic.

The Auschwitz-Birkenau State Museum and Memorial, which is located on the site of the Nazi concentration camp in Oswiecim, Poland, is closed for visitors until at least Jan. 31 under COVID-19 restrictions set by the Polish government.

"Due to the coronavirus pandemic, the commemoration will exceptionally not be held at the Memorial, but in the virtual space," Auschwitz Memorial spokesperson Pawel Sawicki said in a statement Tuesday evening. "The main theme of the 76th anniversary of the liberation will be the fate of children in Auschwitz."

The online events will include testimony from survivors as well as a guided virtual tour of the Auschwitz Memorial, "aimed at enhancing the educational value for visitors from around the globe," according to Sawicki.

Auschwitz, also known as Auschwitz-Birkenau, was a complex of over 40 concentration and death camps run by Nazi Germany in occupied Poland amid the Holocaust during World War II. It was the largest of the Nazi concentration camps and extermination centers. More than 1.1 million men, women and children lost their lives there, mainly Jews, according to information on the Auschwitz-Birkenau State Museum's website.

In January 1945, as Soviet Russia advanced deeper into Nazi-occupied Poland toward the end of the war, Nazi officers organized a forced evacuation of the Auschwitz prisoners. Almost 9,000 prisoners, most of whom were sick or suffering from exhaustion, were deemed unfit to join the death march to Germany. The Nazis intended to kill them all as part of attempts to destroy the evidence of their crimes at Auschwitz, but only managed to murder about 700 Jewish prisoners between the departure of the final evacuation column and the arrival of Soviet forces.

Soviet troops entered Auschwitz on Jan. 27, 1945, a day now commemorated as International Holocaust Remembrance Day, and liberated more than 7,000 survivors, according to the museum's website.
