Pfizer-BioNTech’s Covid-19 vaccine appears to reduce symptomatic coronavirus infections by more than 90% in the real world, Israeli researchers said Sunday. The findings, while preliminary, suggest that the vaccine remains remarkably effective in a mass vaccination campaign — outside the carefully controlled conditions of a clinical trial. The Clalit Research Institute, part of a large

The Covid-19 vaccine rollout started as a trickle. But the pace has steadily picked up each week, more than tripling in the first month under the Trump administration and reaching President Joe Biden’s goal of 1.5 million shots per day just about three weeks into his term. But some aspects of the federal rollout plan

Millions of Americans reeling from a deadly storm and massive power outages are about to get walloped by more winter weather. Already, about 2,000 records for low temperatures have been shattered this past week, CNN meteorologist Dave Hennen said.

The US on Monday reported more than 53,800 new Covid-19 infections: its lowest daily case count since October and a vastly different number from those plaguing the country just last month, when infections were topping 200,000 a day. Statistics across the US are now reflecting more encouraging trends. California, one of the states hit hardest

A genetic test used to detect common traits many people share is not reliable in identifying rare disease-causing variations, such as those that can predict breast and ovarian cancer, a new study has found. The SNP test, which stands for “single nucleotide polymorphism,” is used by direct-to-consumer DNA and ancestry companies to identify common traits

Vaccine distribution in states and cities across the US are slowing down because of winter storms that have left more than a third of the continental US with below-zero temperatures Monday.

After a long day of working from home, Hadly Clark spends her evening hours mindlessly swiping through her phone. She powers through her usual scheduled 9:30 p.m. bedtime in favor of online shopping and social media scrolling. Before Clark knows it, the clock reads 1 a.m. She eventually dozes off and wakes up the next

Researchers said Sunday they have identified a batch of similar troubling mutations in coronavirus samples circulating in the United States. They’ve not only drawn attention to them; they’ve come up with a better shorthand for referring to them. They’ve named them after birds. The mutations all affect the same stretch of the spike protein —

An increasing number of people around the world are opting to go solo. The number of American men and women who have never been married, are divorced or are living alone has been on an upward trend for several years, according to the US Census Bureau. Despite the fact marriages or relationships are less common
