“Right now, we believe these events to be extremely rare, but we are also not yet certain we have heard about all possible cases, as this syndrome may not be easily recognized as one associated with the vaccine,” Dr. Rochelle P. Walensky, the C.D.C. director, said at a White House news conference on the pandemic…
South Africa immediately copied the American pause on Johnson & Johnson vaccinations, infuriating doctors who are still clamoring for shots, especially in remote parts of the country. In February, health officials dropped the AstraZeneca vaccine over its limited efficacy against a dangerous variant there. To date, only half of 1 percent of the population is…
Denmark on Wednesday became the first country to plan to permanently stop administering the AstraZeneca vaccine, a month after suspending its use following reports that a small number of recipients had developed a rare but serious blood-clotting disorder. The director general of the country’s health authority, Soeren Brostroem, said Denmark was able to halt use…
An advisory committee for the Centers for Disease Control and Prevention met on Wednesday to discuss the decision made on Tuesday to pause use of the Johnson & Johnson Covid-19 vaccine because of its possible link to extremely rare blood clots. After a robust afternoon discussion, the panel decided they needed more time to assess…
Keeping the middle seats vacant during a flight could reduce passengers’ exposure to airborne coronavirus by 23 to 57 percent, researchers reported in a new study that modeled how aerosolized viral particles spread through a simulated airplane cabin. “Farther is always better in terms of exposure,” said Byron Jones, a mechanical engineer at Kansas Sate…
In the movies, birth is usually an emergency. It begins with the woman’s water breaking, at the worst possible moment. She appears to be barely in labor, and yet she is rushed, through gridlock traffic, to the hospital. There she becomes angry, and the pain is her husband’s fault. She yells at him, perhaps even…
On Tuesday, several dozen organizations that work on addiction and other health issues asked Mr. Biden’s health and human services secretary, Xavier Becerra, to “act with urgency” and eliminate the rule that doctors go through a day of training before getting federal permission to prescribe buprenorphine. Many addiction experts are also calling for abolishing rules…
Women appear to have more side effects after vaccination than men. A study by the Centers for Disease Control and Prevention, published in February, examined the Pfizer-BioNTech and Moderna vaccines and found that 79 percent of the side effects reported to the agency came from women, even though only 61 percent of the vaccines had…
An advisory committee for the Centers for Disease Control and Prevention will meet on Wednesday afternoon to discuss whether the Johnson & Johnson Covid-19 vaccine should remain paused while a possible link to rare blood clots is investigated. The emergency meeting follows the Food and Drug Administration’s announcement on Tuesday that it was studying six…
The researchers gathered data, too, about each person’s known risk factors for severe Covid, including their age, smoking habits, weight, and any history of cancer, diabetes, organ transplants, kidney problems and other serious, underlying conditions. Then the researchers crosschecked numbers, with arresting results. People in the least-active group, who almost never exercised, wound up hospitalized…
