A record 4 million people in U.S. received a vaccine on Saturday

Aide Macias-Muñoz is often confronted with the accomplishments of her male colleagues. They regularly post on Twitter, celebrating a new publication — or their second one that month. At home in the pandemic, many seem to be churning out more papers than ever.

She’s happy for them, she said. Truly, she is.

Montana Gov. Greg Gianforte has tested positive for the coronavirus, his office said on Monday.

The first-term Republican was tested after showing “mild symptoms” on Sunday, just three days after he received his first covid-19 vaccine dose. Montana’s first lady, Susan Gianforte, has exhibited no symptoms, was tested and is awaiting her results, the governor’s office said in a news release. Gianforte will quarantine for 10 days.

The chief executive of Norwegian Cruise Line Holdings on Monday rolled out a plan to start sailing again from the United States with fully vaccinated passengers and crew. A big catch: He still needs the Centers for Disease Control and Prevention to sign off, more than a year after the agency prohibited cruising in the United States.

The move by CEO Frank Del Rio is a bold salvo amid the cruise industry’s escalating frustration with the CDC, whose allegedly “outdated” rules have been the target of complaints in recent weeks. The criticism has only mounted since Friday, when the agency said travel for vaccinated people was low risk — but also laid out a raft of additional conditions, under a “conditional sailing order,” that cruise lines need to meet before getting permission to operate from U.S. ports.

Since September, Gary Kirby has banned masks and social distancing at his bar on Florida’s Space Coast, refusing to close shop or adopt most restrictions as the coronavirus pandemic continued to rage.

He hosted a keg party for Halloween and turkey bowling for Thanksgiving at Westside Sports Bar and Lounge, in addition to playing football games on weekends. To mark the first anniversary of the state’s first quarantine rules, he planned an “anti-lockdown party” for St. Patrick’s Day.

Twenty U.S. states have now opened vaccine registration to any person over 16 who wants a shot — but the D.C. region is still waiting.

Washingtonians, always loath to be behind in anything, are deeply frustrated as the D.C. region seems to lag, with coronavirus vaccines still hard to come by, even for many people who have long been eligible on the basis of their age, illness or essential work, let alone for healthy young people.

Treasury Secretary Janet Yellen on Monday called for speeding up the distribution of the coronavirus vaccine in poorer nations, arguing the U.S. and global economies are threatened by the impact of covid-19 on the developing world.

While the United States and other rich countries are hoping for a return to normalcy as soon as this fall, many parts of the developing world are not on pace to have widespread vaccination of their populations until 2023 or 2024. Those countries have largely suffered more devastating economic impacts from covid, in part because they do not have the fiscal capacity to authorize the levels of emergency spending approved in the United States.

Facing criticism from several high-profile Republicans in recent weeks, the country’s top infectious-disease expert, Anthony S. Fauci, pushed back on some of the claims, calling the remarks “bizarre.”

The most recent slight came Friday from Sen. Lindsey O. Graham (R-S.C.), who in a series of tweets urged Fauci to visit the U.S.-Mexico border, where authorities are grappling with an influx of migrants, and asked him to witness firsthand what he called the nation’s “biggest super spreader event.”

Health officials in Indiana have begun an investigation into whether anyone was exposed to the coronavirus after a newspaper report about an Alabama fan who reportedly died of covid-19 complications after attending the NCAA men’s basketball tournament in Indianapolis.

Luke Ratliff, a 23-year-old Alabama student and hoops fan known to Crimson Tide fans as “Fluffopotamus,” had attended the school’s March 28 game against UCLA. He returned to Tuscaloosa the day after Alabama lost and was hospitalized.
