When it comes to protecting the world from the coronavirus, two doses of a vaccine may be better than one. But doubling the number of jabs each person needs could complicate efforts to immunize billions of people. The latest results from vaccine front-runners highlight that conundrum. And there is more bad news, albeit from a small study. Recovering from Covid-19 may not offer lasting protection from future infections for those with only mild cases, according to a report on virus antibodies that suggests caution regarding so-called herd immunity, and more darkly, vaccine durability. While President Donald Trump said daily White House pandemic briefings would resume in the face of out-of-control U.S. infections, he has also been focusing attention on anti-police brutality demonstrations. Trump said he would deploy hundreds of armed federal agents to cities run by Democratic mayors, as he has done in Portland, Oregon. Furious critics contend such an escalation—which in Portland has involved federal employees in combat gear without insignia severely injuring protesters and engaging in detentions deemed unconstitutional by legal observers—is an election-year maneuver given recent polls favoring Joe Biden. —David E.

On Tuesday, Biden unveiled a $775 billion plan to bolster child care and care for the elderly. The proposal by the former vice president and presumptive Democratic nominee would be financed by taxes on real-estate investors with incomes of more than $400,000 as well increased tax compliance by high-income earners.

The number of people infected with the coronavirus in parts of the U.S. is reportedly far higher than publicized rates in those regions. The findings suggest many people who didn’t show symptoms or seek medical care may have kept the virus in circulation. California now has 400,000 cases and New York has added more states to its quarantine list. Across the globe, 14.7 million people have been confirmed to be infected and 611,000 have died. The U.S. is still by far the worst hit country in terms of both categories, with 3.8 million confirmed infections and 141,000 dead.

Judy Shelton, a former adviser to Trump’s campaign and his selection to join the Federal Reserve’s Board of Governors, had her nomination advanced in a party-line vote of the Senate Banking Committee. A strict inflation hawk, Shelton long favored returning the U.S. to the gold standard and has questioned the need for a central-bank-controlled benchmark interest rate.

U.S. banks may soon cut back on their real estate holdings to prepare for a world in which fewer workers make a daily commute to the office.

Frackers are in crisis, endangering America’s energy renaissance, Bloomberg Businessweek reports. Even before the pandemic, West Texas was reeling and Wall Street was running out of patience with the industry. But now things are much worse.

Swiss Watch Exports May Be In Big Trouble

The Federation of the Swiss Watch Industry gave the forecast after shipments declined 36% to 6.9 billion francs ($7.4 billion) in the first half. A full-year decline that big would be the worst performance in decades.
