What the Biden-Xi Talks Accomplished (and Didn’t)

Biden and Xi try direct diplomacy The mood music was upbeat but pragmatic after the first face-to-face meeting in a year between President Biden and his Chinese counterpart, Xi Jinping. There was no joint communiqué after Wednesday’s talks, but both sides issued positive statements trumpeting where they found common ground, including on tackling climate change and improving communications. The San Francisco summit, and Xi’s banquet with American business leaders afterward, were signs of how entwined the economies remain despite years of rising tensions — and why both sides and many…

China’s Abrupt Covid Pivot Leaves Many Without Medicines

When demand for fever-reducing drugs more than quadrupled the price of ibuprofen, a city in eastern China began rationing sales by selling the pills individually. When a popular Chinese online pharmacy offered the antiviral drug Paxlovid, it sold out within hours. And when word of the medicine shortages in China reached friends and relatives in Hong Kong and Taiwan, they quickly bought vast quantities of drugs from local sellers to ship to the mainland. As Covid rips through parts of China, millions of Chinese are struggling to find treatment —…

Sinovac Booster Gives Elderly Stronger Protection Against Omicron, Study Finds

Two doses of China’s Sinovac vaccine offered older people only a moderately high level of protection against severe disease and death from Covid-19, but a third dose significantly bolstered their defenses, according to a new study by scientists in Hong Kong. The study, based on patients infected during the current devastating Omicron wave in Hong Kong, serves as a cautionary note for mainland China, where Sinovac is a pillar of the country’s vaccination program. Many older people there have yet to receive booster shots. For people 60 and older, two…

Most of the World’s Vaccines Likely Won’t Prevent Infection From Omicron

A growing body of preliminary research suggests the Covid vaccines used in most of the world offer almost no defense against becoming infected by the highly contagious Omicron variant. All vaccines still seem to provide a significant degree of protection against serious illness from Omicron, which is the most crucial goal. But only the Pfizer and Moderna shots, when reinforced by a booster, appear to have initial success at stopping infections, and these vaccines are unavailable in most of the world. The other shots — including those from AstraZeneca, Johnson…

More Vaccine Mandates

Fully endorsed The F.D.A. granted full approval to the Pfizer-BioNTech coronavirus shots for people 16 and older yesterday, the fastest vaccine approval in the agency’s history. (Although, perhaps, not fast enough.) President Biden seized on the moment. “If you’re a business leader, a nonprofit leader, a state or local leader, who has been waiting for full F.D.A. approval to require vaccinations, I call on you now to do that,” he said. “Require it.” It gives companies more cover to impose vaccine mandates and industry groups more ground to lobby local…
