COVID-19 updates: Anti-vaccine protesters halt vaccinations at Dodger Stadium

The mass COVID-19 vaccination site at Dodger Stadium, one of the largest in the country, was temporarily halted Saturday after the entrance was blocked by anti-vaccine protesters.

The group carried anti-vaccine and anti-mask signs, leading to a long line of cars waiting to get into the stadium, ABC Los Angeles station KABC reported.

The stadium entrance was closed from about 1:50 p.m. to 2:45 p.m., Los Angeles Fire Department Public Information Officer David Ortiz told ABC News. Vaccinations continued inside as the gate was closed, Ortiz said.

A social media post described the demonstration as "SCAMDEMIC PROTEST/MARCH" and advised participants to refrain from wearing pro-Trump or MAGA attire.

"…we want our statement to resonate with the sheeple," the post read, according to The Associated Press. “No flags but informational signs only.”

No arrests were made as a result of the protests.

Republican Arkansas Gov. Asa Hutchinson said Sunday that vaccine distribution has been "seamless" under the Biden administration.

"In terms of the vaccine distribution, it's been seamless. And I was delighted that we had a ... 14% increase in vaccine supply last week. This is going to be very, very important for us. They said they're going to invoke the Defense Production Act. I don't know the details on that, but anything they can do to speed up the production," Hutchinson said on ABC's "This Week."

"Thank goodness we have that partnership which is good with the federal government. And President Biden and his team is -- is working to assure that partnership and not tear it apart, which I'm very grateful for," he told "This Week" Co-anchor Martha Raddatz.

Dave McGillivray, the race director of the Boston Marathon, has been selected by the state of Massachusetts to run the mass vaccination operations at Gillette Stadium and Fenway Park.

McGillivray owns DMSE Sports, which organizes and manages dozens of outdoor events every year. To help keep DMSE Sports afloat, McGillivray connected with CIC Health -- which operates the mass COVID-19 vaccination sites at Fenway Park and Gillette Stadium -- through the state of Massachusetts.

Now, McGillivray is running logistics for both sites.

Fenway Park is the home of the Boston Red Sox, while Gillette Stadium, located in Foxborough, is the home stadium for the New England Patriots. The Gillette Stadium site opened two weeks ago, with Fenway officially opening Monday. Both sites are expected to administer 5,000 doses per day once fully up and running.

The Boston Marathon, usually held in April, has been postponed to October. The in-person event was canceled in 2020, though it was held virtually.

Assistant Secretary of Defense for Public Affairs John Kirby tweeted that the Pentagon is "pausing" the plan to move forward with vaccinations for detainees at Guantanamo Bay.

"We’re pausing the plan to move forward, as we review force protection protocols," Kirby said. "We remain committed to our obligations to keep our troops safe."

No detainees have been vaccinated yet, he said.
