Scientists are finding signals of long covid in blood. They could lead to new treatments.

Scientists are finding signals of long covid in blood. They could lead to new treatments.

The scientists found that people with long covid exhibit changes in a suite of proteins involved in the complement system, which helps the immune system destroy microbes and clear away cellular debris. The results echo what at least one other group has found.  None of the existing research proves that these changes drive the disease. […]

Data show that older adults and people with underlying illness need the vaccine most.

Data show that older adults and people with underlying illness need the vaccine most.

“I would not recommend anything to others that I wouldn’t recommend for my own family,” wrote CDC director Mandy Cohen in an op-ed on Wednesday. “My 9- and 11-year-old daughters, my husband, my parents and I will all be rolling up our sleeves to get our updated Covid-19 vaccines along with our flu shots soon.”  […]

The hunt for a universal covid vaccine

The hunt for a universal covid vaccine

The key to the universal vaccine is the mosaic nanoparticle with so many different viral fragments clustered in close proximity on its surface. The immune system’s B cells, which generate specific antibodies, are likely to find and bind to at least some of these conserved pieces of the virus, which remain unchanged on new variants. […]

She’s at the center of the covid lab leak controversy. Now she’s telling her story.

Some in the West agree. “I’m quite distressed by people throwing this kind of extremely serious allegation around,” Nancy Connell, a microbiologist and member of NIH’s National Science Advisory Board for Biosecurity, told me in February last year, when she was with the Johns Hopkins Center for Health Security. “It’s highly irresponsible.”  But even if the […]

How Pfizer made an effective anti-covid pill

In a statement, the World Health Organization said it believes “prevention is better than cure” and that “these drugs will not be alternatives to vaccines.” The organization, based in Geneva, has yet to make a formal recommendation in favor of Paxlovid and says it wants to track whether side effects emerge. “It’s going to be […]

India grapples with covid grief

“I haven’t seen anything on this scale of pandemic grief ever,” says Shah Alam Khan, an orthopedic oncologist and professor at Delhi’s All India Institute of Medical Sciences. “Previously, you saw numbers of people who died from covid. Now, there are names. Each and every one of us knows someone who has been taken away […]

Vaccine waitlist Dr. B collected data from millions. But how many did it help?

The company has continued to promote the idea of a nationwide service, with online posts claiming the service “is available in all 50 states.” When asked exactly how large its network is, Massoumi told MIT Technology Review that Dr. B does not have nationwide coverage but has around 600 vaccination partners across 37 states—although the […]

Top researchers are calling for a real investigation into the origin of covid-19

The letter, which was organized by the Stanford University microbiologist David Relman and the University of Washington virologist Jesse Bloom, takes aim at a recent joint study of covid origins undertaken by the World Health Organization and China, which concluded that a bat virus likely reached humans via an intermediate animal and that a lab […]
