Several more states on Thursday announced COVID-19 vaccines would be available to more people, news that came as the nation’s top infectious disease expert said we might need to inoculate children to reach herd immunity. But, Dr. Anthony Fauci said people are too focused on the thought of herd immunity — the point at which

Low-dose aspirin may help protect the lungs and reduce the need to put patients on ventilators, researchers reported Wednesday. The cheap and widely available pills also keep patients out of ICUs and can reduce the risk of death, probably by preventing tiny blood clots, a team at George Washington University reported in a study published

Experts say there’s a tough race between COVID-19 vaccinations and a contagious variant that’s rapidly spreading across the US, threatening another dangerous surge — and the eased restrictions only further complicate things. “It’s going to be a close call,” Dr. Ashish Jha, dean of the Brown University School of Public Health told CNN on Tuesday.

What was nice about the Before Times was that, for most people, social interactions and outings could be carefree. We miss them, and that’s a big reason why we long for the pandemic to end.

Since the start of the pandemic, the most terrifying task in health care was thought to be when a doctor put a breathing tube down the trachea of a critically ill COVID patient.
