Indoor dining will return to New York City on Valentine’s Day at 25% capacity, New York Gov. Andrew Cuomo said Friday.

Indoor dining was shut down in New York City in December.

On March 15, in-person weddings can resume in New York at 50% capacity, or up to 150 people, he said.

Meanwhile, in hard-hit Los Angeles County, outdoor dining is now allowed to reopen at 50% capacity, but with a restriction: TVs must remain off.

Dr. Jay Butler, deputy director for infectious diseases at the Centers for Disease Control and Prevention, said Friday the U.S. has seen a decline in the last two weeks of new cases and hospitalizations, which is “encouraging." But, he added, "The numbers nationally are still high."

"The pandemic is not yet over yet," Butler told the Infectious Diseases Society of America. "By the time we end our 45 minutes together, roughly 100 more Americans will have died of COVID-19."

Butler stressed that the vaccines are safe and effective and that mild side effects are normal.

"The available data tells us that more than half of people have reported some degree of tiredness and pain at the injection site, although most are able to continue normal daily activities," Butler said. "Many also report symptoms such as headache, muscle pain or chills after getting their shots, particularly in the first couple of days. These data also suggest that it may be more common among younger persons after the second dose, but again, this is expected based on some of the data that were available from the clinical trials."

AstraZeneca’s vaccine on Friday was recommended for conditional marketing authorization in the European Union for people 18 and older. The vaccine is given as two doses.

This is the third vaccine, following Pfizer and Moderna, to be approved by the European Medicines Agency. The AstraZeneca vaccine now awaits final say from the European Commission.

In another promising development for vaccine science, Johnson & Johnson announced Friday that its COVID-19 vaccine -- a single shot tested against a complex barrage of newly emerged variants of the virus -- is 66% effective at preventing symptomatic disease and 85% effective against preventing severe illness.

The U.S. pharmaceutical giant said the vaccine is also safe to take. Volunteers experienced mild reactions after the shot, with less than 10% experiencing fever, according to a company press release.

The full data package will be made publicly available and will be evaluated by the FDA's advisory committee sometime in mid- to late February.

The Food and Drug Administration has said it will consider a vaccine that's more than 50% effective, and the Johnson & Johnson vaccine exceeds this threshold. An emergency use authorization could be given and people could start receiving shots before the end of February.

Dr. Anthony Fauci, the nation's leading infectious disease expert, opened up about his experience working with former U.S. President Donald Trump in an interview with The New York Times that was published Sunday.

When COVID-19 began to rapidly spread in the northeastern part of the country last year, particularly in New York City, Fauci said Trump had "almost a reflex response" to try to "minimize" the situation.

"I would try to express the gravity of the situation, and the response of the president was always leaning toward, 'Well, it's not that bad, right?' And I would say, 'Yes, it is that bad,'" Fauci, director of the National Institute of Allergy and Infectious Diseases, told the newspaper. "It was almost a reflex response, trying to coax you to minimize it. Not saying, 'I want you to minimize it,' but, 'Oh, really, was it that bad?'"

Fauci, who was a key member of the Trump administration's coronavirus task force, said another thing that made him "really concerned" was the former president taking input from non-experts on unproven methods to treat COVID-19, like hydroxychloroquine.

"It was clear that he was getting input from people who were calling him up, I don’t know who, people he knew from business, saying, 'Hey, I heard about this drug, isn't it great?' or, 'Boy, this convalescent plasma is really phenomenal,'" Fauci told the newspaper. "And I would try to, you know, calmly explain that you find out if something works by doing an appropriate clinical trial; you get the information, you give it a peer review. And he’d say, 'Oh, no, no, no, no, no, no, no, this stuff really works.'"

"He would take just as seriously their opinion -- based on no data, just anecdote -- that something might really be important," Fauci added. "That’s when my anxiety started to escalate."

When the leadership of the White House coronavirus task force changed hands last February, with U.S. Vice President Mike Pence coordinating the government's response and Trump at the podium taking questions from reporters during the press briefings, Fauci said it went from "the standard kind of scientifically based, public-health-based meetings" to "the anecdotally driven situations, the minimization, the president surrounding himself with people saying things that didn’t make any scientific sense."

"Then I started getting anxious that this was not going in the right direction," he told the newspaper. "We would say things like: 'This is an outbreak. Infectious diseases run their own course unless one does something to intervene.' And then he would get up and start talking about, 'It’s going to go away, it’s magical, it’s going to disappear.'"

That's when Fauci said it became clear to him that he needed to speak up, even if it meant contradicting the president.

"He would say something that clearly was not correct, and then a reporter would say, 'Well, let’s hear from Dr. Fauci.' I would have to get up and say, 'No, I’m sorry, I do not think that is the case,' he told the newspaper. "It isn’t like I took any pleasure in contradicting the president of the United States. I have a great deal of respect for the office. But I made a decision that I just had to. Otherwise I would be compromising my own integrity, and be giving a false message to the world. If I didn’t speak up, it would be almost tacit approval that what he was saying was OK."

This upset Trump's "inner circle," Fauci said.

"That’s when we started getting into things I felt were unfortunate and somewhat nefarious -- namely, allowing Peter Navarro to write an editorial in USA Today saying I’m wrong on most of the things I say," he told the newspaper. "Or to have the White House press office send out a detailed list of things I said that turned out to be not true -- all of which were nonsense because they were all true. The very press office that was making decisions as to whether I can go on a TV show or talk to you."

Fauci said there were a couple times where Trump even called him personally to say, "Hey, why aren’t you more positive? You’ve got to take a positive attitude. Why are you so negativistic? Be more positive."

Fauci said he and his family have received death threats, beginning last March, and that his wife once suggested he consider quitting.

"But I felt that if I stepped down, that would leave a void. Someone’s got to not be afraid to speak out the truth," he told the newspaper. "Even if I wasn’t very effective in changing everybody's minds, the idea that they knew that nonsense could not be spouted without my pushing back on it, I felt was important. I think in the big picture, I felt it would be better for the country and better for the cause for me to stay, as opposed to walk away."
