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.

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.
