an immediate pause in the use of Johnson & Johnson’s single-dose Covid-19 vaccine after six recipients in the United States developed a rare disorder involving blood clots within one to three weeks of vaccination.

  • All 50 states, Washington, D.C. and Puerto Rico temporarily halted or recommended providers pause the use of the vaccine. The U.S. military, federally run vaccination sites and a host of private companies, including CVS, Walgreens, Rite Aid, Walmart and Publix, also paused the injections.
  • Fewer than one in a million Johnson & Johnson vaccinations are now under investigation. If there is indeed a risk of blood clots from the vaccine — which has yet to be determined — that risk is extremely low. The risk of getting Covid-19 in the United States is far higher.
  • The pause could complicate the nation’s vaccination efforts at a time when many states are confronting a surge in new cases and seeking to address vaccine hesitancy.
  • Johnson & Johnson has also decided to delay the rollout of its vaccine in Europe amid concerns over rare blood clots, dealing another blow to Europe’s inoculation push. South Africa, devastated by a more contagious virus variant that emerged there, suspended use of the vaccine as well. Australia announced it would not purchase any doses.
  • “The virus can spread across borders, but mankind’s love also transcends borders,” he told reporters.

    This week China’s main Covid-19 vaccine manufacturer, Sinovac, made a gesture that is certain to fuel speculation about Beijing’s plans in Paraguay. The South American soccer federation Conmebol, which is based in Paraguay, announced it was receiving a donation of 50,000 doses of CoronaVac, the Covid-19 vaccine produced by Beijing-based Sinovac.

    “The leaders of this company have understood the enormous social and cultural value of soccer in South American countries,” the federation’s president, Alejandro Domínguez, said in a statement, calling the donation a “noble gesture.”

    Despite all these signals, Taiwan’s position in Paraguay may be safer than it appears, said Lee McClenny, who served as the U.S. ambassador in Paraguay until last September. While cabinet members and businessmen have pressured President Mario Abdo Benítez to forge ties with China, the Chinese government didn’t show much interest in getting Paraguay to flip, he said.

    “On the ground I didn’t see very effective efforts to make this happen,” Mr. McClenny said.

    Besides, Mr. McClenny added, the Paraguayan president takes a special pride in the relationship with Taiwan, which was brokered in the 1950s by his late father, who served as the personal secretary to Alfredo Stroessner, the dictator who ran the country for 35 years. And Taiwanese aid has made a major impact in the landlocked, impoverished nation.

    “It’s effective and benefits people’s lives in real ways,” Mr. McClenny said about Taiwan’s assistance.

    The Biden administration has signaled its unease about the prospect that Paraguay could cut a deal with China. In a phone call with Mr. Abdo Benítez last month, Secretary of State Antony J. Blinken urged the Paraguay government to continue to “work with democratic and global partners, including Taiwan, to overcome this global pandemic,” according to a summary of the call provided by the State Department.

    That message rankles opposition lawmakers, including the leftist Senator Esperanza Martínez, who served as health minister from 2008 to 2012. Ms. Martínez has long favored establishing relations with China, arguing that Paraguay stands to benefit in the long run by expanding trade. She said Washington’s exhortation was immoral.

    “We’re being loyal to people who impose rules on us while we die,” she said. “Our allies are vaccinating people morning, afternoon and night while they block us from getting vaccines, saying we’ll turn into communists.”
