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…

As Omicron Surges and Economy Suffers, China Tweaks ‘Zero Covid’
When the coronavirus first swept across China in early 2020, the country’s leader, Xi Jinping, declared a “people’s war” against the epidemic, launching what would become a no-holds-barred strategy to eliminate infections. Now, in year three of the pandemic, and faced with the rise of a stealthy and rapidly spreading variant, Mr. Xi is trying to fine-tune the playbook, ordering officials to quash outbreaks — but also to limit the economic pain involved. As China grapples with the country’s largest outbreak since the pandemic began in Wuhan more than two…
Confusion and Chaos in Hong Kong as Leaders Fumble Virus Response
HONG KONG — From week to week as infections barreled through the city, residents in Hong Kong watched the government’s coronavirus policies change. First, officials said they didn’t have plans for social distancing in January, then promptly shut down bars and gyms and banned flights from eight countries. In February, the officials vowed to test every resident, then appeared to abandon those plans this month. And on Thursday, public beaches were closed just three days after Carrie Lam, the city’s leader, raised the possibility of relaxing Covid-19 restrictions. As Hong…
Omicron Surge in Asia Restricts Travel for Lunar New Year
The Omicron variant has dampened the plans of tens of millions of people across several Asian countries to travel during the Lunar New Year, as officials battle the pandemic for a third year. Observed this year on Feb. 1, Lunar New Year falls just as many countries are seeing surges in coronavirus cases. Omicron is becoming the dominant variant in countries like South Korea, which expects up to 90 percent of its cases to be Omicron-related by the end of February. Before the pandemic, as many as three billion trips…
Tianjin, a city of 14 million near Beijing, starts testing all residents after Omicron surfaces.
Officials in the northern Chinese port city of Tianjin, near Beijing, said on Sunday that its entire population of 14 million would be tested for the coronavirus after it was found in 20 residents, at least two of whom were infected with the fast-moving Omicron variant. The city also announced a raft of restrictions in an effort to contain the outbreak and trace its source. The first infections were confirmed on Saturday, in a 10-year-old girl and a 29-year-old woman who works at an after-school center. Tracing and testing later…
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…

China Calls on ‘Little Inoculated Warriors’ in Its War on Covid-19
As the rest of the world struggles to vaccinate adults in the face of a threat from a new coronavirus variant, China has embarked on an ambitious campaign that it says will give the country better protection against Covid-19: full inoculation of 160 million of its youngest citizens by the end of the year. The campaign — powered in part with red flower stickers, balloons and boxes of toys for children who step up to become what nurses call “little inoculated warriors”— has gotten off to a fast start. In…
