When will we all be vaccinated for COVID-19?
When will the COVID-19 vaccine be available to everyone?
Anthony Fauci, Biden's chief medical adviser, says he believes virtually every American adult will be eligible for a vaccine in April. From then, he said, “it would likely take at least several more months just logistically to get vaccine into people’s arms.”  
During a March 11 speech, Biden said that he would direct states, tribes, and territories to make all adults eligible for vaccination by May 1. 
A new vaccine: The FDA authorized the Johnson & Johnson vaccine on Feb. 27. Unlike the Moderna and Pfizer-BioNTech vaccines, the Johnson & Johnson vaccine requires only one dose and can be stored at the temperature of a normal refrigerator for up to three months. This will ease the challenges of distribution as well as the manufacturing and administration burden, as only half the number of doses are required to vaccinate the same number of people.Increased supply: Pfizer and Moderna will deliver 100 million doses a month earlier than expected, in May instead of June.The Biden administration also helped broker a deal in which Merck, a competing pharmaceutical company, will help manufacture Johnson & Johnson vaccines. Biden invoked the Defense Production Act to speed up production and ensure Merck factories are well-equipped to manufacture the vaccines.

Nicolas Cage, 57, tied the knot for a fifth time to 26-year-old Riko Shibata in Las Vegas on Feb. 16, the actor's representative Shannon Barr confirmed to USA TODAY in March. 
"It’s true, and we are very happy," Cage said in a statement.
The newlyweds exchanged traditional Catholic and Shinto vows during their intimate ceremony at Las Vegas' Wynn Hotel. Shibata wore a handmade Japanese bridal kimono from her native country while Cage opted for a Tom Ford tuxedo. The wedding ceremony was followed by a small reception attended by Cage's ex-wife Alice Kim and their 15-year-old son Kal-El. Cage also shares son Weston, 30, with actress Christina Fulton.








Movies delayed (again) by COVID-19 2021
Welcome to the new normal: Movie studios are still scrambling to shift large chunks of their film releases in response to the ongoing coronavirus pandemic and cinema closures. (Or, now in some states and other parts of the world, gradual cinema reopenings. Thanks, Tenet!) China made the decision to shut down movie theaters as far back as January 2020 in an effort to contain the virus, and prominent production companies have also closed down indefinitely. While many smaller films that had day-and-date theatrical and on-demand debuts have proceeded with the digital parts of those releases, tentpole movies out of Marvel and The Fast saga, to name just a few, have been reshuffled and moved countless times to 2021, 2022, or are being delayed indefinitely. No Time to Die, Avatar 2, and West Side Story are also dancing to new dates, and Disney has relegated three of its films to streaming debuts. With all that in mind, here’s a guide to the movies that have been delayed so far because of COVID-19, with new release dates listed where available.

CPAC: Trump rips Biden and GOP critics
Donald Trump at CPAC: Ex-president tears into Biden and his Republican critics.ORLANDO, Fla. – Donald Trump reentered political life Sunday by attacking President Joe Biden, condemning Republican opponents and proclaiming himself the leader of a GOP riven by election defeats and the pro-Trump insurrection at the U.S. Capitol in January.
"Do you miss me yet?" Trump asked the Conservative Political Action Conference after taking the stage more than an hour after his scheduled start time. "A lot of things going on."
Trump's attacks on other Republicans – and his support of primary challengers to some GOP lawmakers – threaten to divide the party further as it tries to regain control of Congress in 2022 and the White House in 2024.Before the speech, Republicans said the party can win elections in 2022 and 2024 only by asking voters to agree with them on issues, not on Trump. Sen. Bill Cassidy, R-La., told CNN's "State of the Union" that the GOP should not put one man on "a pedestal."

"I wouldn’t say he's thought a lot about the former president’s visit – I was going to say 'performance,' maybe that’s appropriate – at CPAC," said White House press secretary Jen Psaki.
