The state of California is poised to surpass 3 million positive COVID-19 cases within two days, according to data from the California Department of Public Health.

On Sunday, the state health department reported 42,229 new cases and 432 new deaths.

Los Angeles County, the hardest hit in the state, surpassed 1 million cases on Saturday. Dodger Stadium, the largest vaccination site in the country, reopened on Friday, but officials told ABC News they only have enough doses to last until Wednesday.

New York Gov. Andrew Cuomo is urging the federal government to send more COVID-19 vaccines to the state as the variant that originated in the U.K. continues to spread.

Nearly 14,000 positive tests were reported Sunday, with 18 known cases of the variant and an infection rate of 5.6%, Cuomo announced.

While 7 million New York residents are currently eligible to receive the vaccine, the federal government sent less vaccines than what was expected, he added.

"We have the weapon that will win this war and we can see the light at the end of the tunnel, but how fast we get there depends upon two things-our own individual actions and the federal supply, which is where we are facing the greatest challenge," Cuomo said in a statement.

The U.S. is forecast to have almost 500,000 COVID-19 deaths by mid-February, incoming CDC Director Dr. Rochelle Walensky said on CBS’ "Face the Nation" Sunday morning.

She added, "That doesn't speak to the tens of thousands of people who are living with a yet uncharacterized syndrome after they've recovered."

Walensky, who was appointed by the Biden administration, believes that 100 million more doses of the vaccine will be available within the next 100 days.

"That is what the president-elect has promised," she said. “It will be a hefty lift, but we have it in us to do that.”

People seeking COVID-19 vaccines in Houston were sent away from Minute Maid Park after appointments were overbooked.

The Houston Health Department announced Saturday that it had run out of vaccines by 6 p.m. after it had administered 5,451 doses at the site, where the line wrapped around the building, ABC Houston station KTRK reported. Several people left without getting vaccinated.

Houston Health Department Stephen Williams said during a press conference Saturday he warned the mayor that there wouldn’t be enough doses to last the week.

The city received “a little” over 30,000 doses, Houston Mayor Sylvester Turner said in a statement.

Pope Francis and his predecessor, Pope Emeritus Benedict XVI, have received their first dose of a COVID-19 vaccine, according to Vatican spokesman Matteo Bruni.

"I can confirm that as part of the Vatican City State vaccination program to date, the first dose of the COVID-19 vaccine has been administered to Pope Francis and the Pope Emeritus," Bruni said in a statement Thursday.

Francis, who turned 84 last month and had part of a lung removed when he was younger, reportedly received the shot Wednesday while Benedict, 93, reportedly got it Thursday.

Vatican City, an independent enclave surrounded by Rome that serves as the headquarters of the Roman Catholic Church, launched the immunization campaign on Wednesday, administering doses of a COVID-19 vaccine developed by U.S. pharmaceutical giant Pfizer and its German partner BioNTech.

The tiny city-state has a population of only around 800 people but employs more than 4,000. It's unclear how many doses of the Pfizer/BioNTech vaccine have been procured so far.

Vatican City citizens, along with employees and pensioners, will have the opportunity to receive the vaccine as well as family members who are entitled to use of the city-state's health care system. Priority is being given to health care workers, public safety personnel, the elderly and individuals who are most frequently in contact with the public, according to Bruni.

The vaccination campaign is voluntary and people under the age of 18 are being excluded for the time being, Bruni said.

Since the start of the pandemic, Vatican City has reported at least 27 confirmed cases of COVID-19, according to a real-time count kept by Johns Hopkins University.
