How to Double the Vaccination Pace

The development of the Covid-19 vaccines happened with great urgency, for obvious reasons.

One of the timesaving techniques by Moderna and Pfizer involved scheduling the two vaccine doses fairly close together — just three or four weeks apart — during the research trials. The companies did not test multiple gaps between the two shots to see which was the most effective. They each chose a short gap to finish the trials as quickly as possible.

The decision made a lot of sense. It allowed the U.S. mass vaccination program to start in December, rather than pushing it back a few

After Nuclear Site Blackout, Thunder From Iran, and Silence From U.S.

JERUSALEM — The last time the centrifuges crashed at Iran’s underground nuclear fuel-production center at Natanz, more than a decade ago, the sabotage was the result of a joint Israeli-American cyberattack intended to slow Tehran’s progress toward nuclear weapons and force a diplomatic negotiation.

When they crashed again this weekend, the White House asserted that the United States had no involvement.

The operation raised the question of whether Israel was acting on its own to strike Iran and undermine American diplomacy as the Biden administration seeks to reconstitute a nuclear agreement. Or, alternatively, whether Israel was operating in concert with

The Iran Nuclear Talks, Explained

BRUSSELS — In Vienna last week, the signers of the 2015 Iran nuclear deal came together with what would appear to be a simple task. They wanted to restore compliance with an agreement that puts strict controls on Iran’s nuclear enrichment, to ensure that it cannot build a nuclear weapon, in return for the lifting of punishing economic sanctions.

Both Iran and the United States insist that they want to return to the deal, known as the Joint Comprehensive Plan of Action. But nothing about the meetings is simple.

The first sessions went well, with working groups established to try

A Clash of Wills Keeps a Leonardo Masterpiece Hidden

French curators had worked for a decade to prepare a major exhibition marking the 500th anniversary of the death of Leonardo da Vinci. When it opened, though, the most talked-about painting they had planned to show — “Salvator Mundi,” the most expensive work ever sold at auction — was nowhere to be seen.

Plucked from shabby obscurity at a New Orleans estate sale, the painting had been sold in 2017 as a rediscovered “lost” Leonardo and fetched more than $450 million from an anonymous bidder who kept it hidden from view. The chance to see it at the Louvre museum’s

Myanmar Protests, and Killings, Continue

The Myanmar military’s bloody crackdown on the nationwide resistance to its rule showed no sign of easing on Sunday, with a human rights group reporting that the death toll across the country had passed 700.

The security forces killed 82 people in a single city on Friday, according to the group, the Assistance Association for Political Prisoners, which has been documenting the bloodshed since the military’s Feb. 1 coup. Soldiers used machine guns and rocket-propelled grenades to attack an organized group of protesters who had set up barricades to defend part of that city, Bago.

The military appears to be

New Hampshire and Oklahoma Move to Open Covid Vaccines to Nonresidents

New Hampshire and Oklahoma announced plans this week to open up vaccine eligibility to outside residents as supply grows and more states expand eligibility.

Gov. Chris Sununu, Republican of New Hampshire, said officials were confident that there would be enough shots to vaccinate outside residents by April 19, the same day that President Biden has called for every state to make all adults eligible for a shot. Mr. Sununu said New Hampshire was “well ahead” of that deadline after making all adults ages 16 or older in the state eligible for a vaccine on April 2.

“We’re going to have

Royal Rivalry Bares Social Tensions Behind Jordan’s Stable Veneer

In recent years, Prince Hamzah has spoken out against high-level corruption, an issue the public associates with privatization. And he has visited tribal leaders and attended tribal events, perceived as a provocative attempt to foment tribal frustration and social discontent.

“He didn’t create these grievances,” said Mr. Ramadan, the former lawmaker. “He tapped into them.”

But before Prince Hamzah reinvented himself as a government critic, he was the epitome of a palace insider. After King Abdullah inherited the crown in 1999 from their father, King Hussein, he appointed Prince Hamzah as his own crown prince and successor.

King Abdullah, 59, …

Iran Nuclear Talks Start on Positive Note in Vienna

BRUSSELS — Talks in Vienna aimed at reinvigorating the Iran nuclear deal that the Trump administration left in 2018 and which Tehran began breaking a year later made some progress this week: They didn’t break down.

Senior diplomats involved in the talks agreed on Friday that initial steps in two working groups designed to bring both the United States and Iran back into compliance with the accord were positive and would continue next week.

Although there are no direct talks between Iran and the United States, the other signatories to the deal — Britain, China, France, Germany and Russia, under

Volcano Erupts on Island of St. Vincent and the Grenadines

KINGSTOWN, St. Vincent and the Grenadines — A volcano in the southern Caribbean that had been dormant for decades erupted in a billowing blast of gray smoke Friday, spewing clouds of ash for miles and forcing thousands to evacuate.

The volcano, known as La Soufrière, on the northern tip of the main island of St. Vincent, in St. Vincent and the Grenadines, had started showing signs of renewed activity in late December.

It moved into an “explosive state” on Friday morning, the National Emergency Management Organization said in a Twitter posting.

Chinese Shows Blur Western Brands Over Xinjiang Cotton Dispute

HONG KONG — Viewers of some of China’s most popular online variety shows were recently greeted by a curious sight: a blur of pixels obscuring the brands on sneakers and T-shirts worn by contestants.

As far as viewers could tell, the apparel showed no hints of obscenity or indecency. Instead, the problem lay with the foreign brands that made them.

Since late March, streaming platforms in China have diligently censored the logos and symbols of brands like Adidas that adorn items worn by contestants performing dance, singing and standup-comedy routines. The phenomenon followed a feud between the government and big-name
