Health workers who picked their noses were more likely to contract COVID, according to a new study. But here’s what the study means for the rest of us.

COVID vaccines are not likely to blame for any major changes to the menstrual cycle, a new study shows.

At least 20% of people who become infected with the SARS-CoV-2 coronavirus never feel sick. Now scientists have identified a genetic mutation that is linked to a higher likelihood of avoiding symptoms during infection.

Researchers tracked 2,300 wild mammals during the strict 2020 lockdowns and found they moved 73% further than in the previous year.

People who took a cheap diabetes drug after testing positive for COVID-19 had a 40 percent lower risk of getting long COVID, a US-based study said Friday.

The comments are the first admission by a senior official that Beijing’s took the so-called Wuhan lab leak theory seriously after years of heated denials.

Beijing officially investigated Wuhan lab, former head of China's Centre for Disease Control suggests...

University of Sydney scientists have found a receptor protein which ‘acts a bit like molecular velcro, in that it sticks to the spike of the virus’

An updated Cochrane Review suggests face masks don’t reduce the spread of COVID in the community. But there are several reasons why this conclusion is misleading.

A Project Veritas video claimed that it featured someone named “Jordon Trishton Walker, Pfizer Director of Research and Development - Strategic Operations and mRNA Scientific Planning.”

Mortality statistics show 122,000 deaths in excess of normal levels across 14 countries analysed by the FT

The new approach would simplify vaccination guidance so that, every fall, people would get a new shot, updated to try to match whatever variant is dominant.

U.S. drugmaker Pfizer Inc said on Tuesday it will offer its full portfolio of drugs, including off-patent medicines such as chemotherapies and oral cancer treatments, on a not-for-profit basis to 45 low-income countries in the world.

Individuals with long COVID, sometimes referred to as “long-haulers,” experience symptoms that may persist for weeks, months, or even years after their acute viral infection. While symptoms vary widely, a common complaint among patients is “brain fog”—a colloquial term for significant, persistent cognitive deficits, with consistent impairment of executive functioning and working memory.

Genome analysis finds SARS-CoV-2 and bat coronaviruses shared an ancestor just a few years ago, but extensive recombination has muddied the picture.

A string of about 30,000 genetic letters were all that it took to start the nightmare of covid-19, the death toll from which is likely to be more than 20m. Exactly how this story began has been hotly contested. Many think that covid-19’s emergence was a zoonosis—a spillover, as so many new pathogens are, from wild animals, for it resembles a group of coronaviruses found in bats.

When COVID-19 was filling emergency rooms, shuttering businesses, and turning parents and teachers into experts in Zoom, everyone hoped for a cure — or, if that wasn't possible, at least a way to avoid getting it. However, when a vaccine became available, many were wary of it. Rumors quickly spread about "the jab": It gives you cancer. It was approved before enough research could be done. It restructures your DNA. All these are false, according to Memorial Sloan-Kettering Cancer Center, but that hasn't stopped the rumor mill from grinding.

Drugmaker Pfizer said Friday that as government contracts come to an end, possibly by early next year, its Covid-19 vaccine will be sold for $110 to $130 per dose.

The pandemic coronavirus' debut wrought universal havoc—not even seasonal flu viruses were spared. Amid travel restrictions, quarantines, closures, physical distancing, masking, enhanced hand washing, and disinfection, the 2020-2021 flu season was all but canceled. That meant not just an unprecedented global decrease in the number of people sick with the flu but also a dramatic collapse in the genetic diversity of circulating flu strains.
