Vault, a P.C.R. test, offers an at-home test kit for travel from Jamaica, Mexico and the Dominican Republic to the United States. The kits cost $119 and include a video session with a qualified professional; there are drop-off points for samples across these countries’ major cities, with results of the P.C.R. test returned 12 to […]
Some experts questioned whether Moderna had gathered enough data on potential side effects. Regulators and scientists have been especially concerned about the risks of the heart conditions myocarditis, or inflammation of the heart muscle, and pericarditis, or inflammation of the lining around the heart. The F.D.A. in June attached warnings about those risks to the […]
After a brutal summer surge, driven by the highly contagious Delta variant, the coronavirus is again in retreat. The United States is recording roughly 90,000 new infections a day, down more than 40 percent since August. Hospitalizations and deaths are falling, too. The crisis is not over everywhere — the situation in Alaska is particularly […]
The advisory committee is also likely to consider whether Moderna’s protection against severe disease and hospitalization may eventually weaken. Booster proponents argue that Moderna’s potency is declining much like Pfizer’s, which is based on the same technology, only more slowly because its initial dosage is significantly stronger than Pfizer’s and the interval between the first […]
People who received a Johnson & Johnson coronavirus vaccine may be better off with a booster shot from Moderna or Pfizer-BioNTech, according to preliminary data from a federal clinical trial published on Wednesday. That finding, along with a mixed review of Johnson & Johnson’s booster data from the Food and Drug Administration released earlier in […]
The Food and Drug Administration for the first time on Tuesday authorized an electronic cigarette to be sold in the United States, a significant turn in one of the most contentious public health debates in decades.

The new committee, known as the Scientific Advisory Group for the Origins of Novel Pathogens, will differ in several respects from the team that the W.H.O. sent to China. Because that team visited Wuhan, China had considerable influence over its membership. That is not the case for the new committee, a permanent panel that Dr. […]
As the virus spread, more mutations sprang up, giving rise to even more transmissible variants. First came Alpha, which was about 50 percent more infectious than the original virus, and soon Delta, which was, in turn, roughly 50 percent more infectious than Alpha. “Now we’re basically in a Delta pandemic,” said Robert Garry, a virologist […]
Cómo la industria de alimentos está haciendo frente a la sal Ya en 1979, un grupo consultivo encargado por la Administración de Alimentos y Medicamentos (FDA, por su sigla en inglés) recomendó que se reconsiderara el estatus de la sal como “generalmente reconocida como segura”. Pero la agencia solo pidió a la industria alimenticia que […]
When Lizzie Rothwell, an architect in Philadelphia, sent her son to third grade this fall, she stocked his blue L.L. Bean backpack with pencils, wide-ruled paper — and a portable carbon dioxide monitor. The device gave her a quick way to assess how much fresh air was flowing through the school. Low levels of CO2 […]
