While the origins of smallpox has remained a mystery for centuries, researchers now believe that it dates back 2,000 years earlier than previously thought.
Until recently, the earliest genetic evidence of smallpox, the variola virus, was from the 1600s. And in 2020, researchers found evidence of it in the dental remains of Viking skeletons, pushing its existence 1,000 years earlier.
It's safe for kids to take the COVID-19 vaccine after they’ve suffered a rare complication from a prior COVID infection, a U.S. National Institutes of Health-supported study has concluded.
Multisystem inflammatory syndrome in children (MIS-C) affects about 1 in every 3,000 to 4,000 kids who contract COVID-19, according to the U.S. Centers for Disease Control and Prevention.
COVID-19 patients could soon have a new antiviral pill they can take to guard against severe disease.
The treatment, called VV116, worked as well as Paxlovid in people who were at high risk of severe disease in a phase 3 trial in China.
The trial was a “great success,” study co-author Ren Zhao, a professor at Shanghai Jiao Tong University School of Medicine, said in a
While getting a COVID-19 vaccine provides antibodies against the coronavirus, getting a booster shot creates a longer-lasting antibody response, according to new research.
“These results fit with other recent reports and indicate that booster shots enhance the durability of vaccine-elicited antibodies,” said senior researcher
One of the hallmarks of a COVID-19 infection has been a lost sense of smell after the infection ends.
In a new study, researchers blame an ongoing immune assault on the olfactory nerve cells — cells found at the top of the nasal cavity — and a decline in the number of those cells. The study was led by a team at Duke Health in Durham, N.C.
“One of the first symptoms that has ty...
