A new DNA sensor can detect viruses and tell if they are infectious or not in minutes, a new study finds.

The sensor was developed by using DNA technology, and does not require the need to pretreat test samples. Researchers demonstrated this technique with the human adenovirus (which causes colds and flu) and the virus that causes COVID-19.

"The infectivity status is very important...

The future of COVID-19 treatments might include a tiny antibody made by llamas.

British researchers credit a llama named Fifi with their finding.

The investigators said these llama nanobodies, which are also produced by camels, could eventually be produced in a lab and administered by a nasal spray, binding tightly to the COVID-19 virus and neutralizing it.

The potential solu...

One way to help protect newborns from COVID-19 is for women to get their COVID vaccine while pregnant.

A new study found that mothers-to-be who had either the Pfizer-BioNTech or Moderna vaccine passed high levels of antibodies to their infants.

Researchers from the NYU Grossman School of Medicine discovered that 100% of 36 newborns tested at the time of birth had protective antibo...

Antibodies from current COVID-19 vaccines don't bind well to the new variants of the virus, a study finds.

Researchers collected data from previously published papers about the sequence of antibodies produced by the vaccines. They focused on antibodies against the spike protein, a part of the virus that binds to receptors on human cells to infect them. It's the target of most vaccines.

Getting another shot of the Johnson & Johnson COVID-19 vaccine substantially increased its protection, the company announced Tuesday.

According to the results of a new clinical trial, two doses of the vaccine boosts immunity to 94% from the 74% offered by a single dose, the company said in a statement.

"Our single-shot vaccine generates strong immune responses and long-lasting immun...

As the highly contagious Delta variant has swept across the United States, the country has reached a tragic milestone.

COVID-19 has now killed more Americans than the 1918 Spanish flu pandemic did, when roughly 675,000 people died.

It didn't have to be that way.

"Big pockets of American society — and worse, their leaders — have thrown this away" by not getting vaccinated, ...

If a person is diagnosed with COVID-19 in the United States right now, it's almost certainly caused by the Delta variant.

The highly transmissible variant, which caused crippling surges in India and Britain this past spring and fueled case spikes in the United States this summer, is now responsible for over 99% of all cases tracked in this country, according to the latest data from the

A study of millions of people vaccinated against COVID-19 has identified those at greatest risk of hospitalization and death after breakthrough infection.

The most vulnerable are those who are immunosuppressed from chemotherapy, a recent bone marrow or solid organ transplant, or HIV/AIDS. Also at risk are people with neurological disorders (such as dementia and Parkinson's disease), nur...

An advisory panel to the U.S. Food and Drug Administration on Friday recommended a third Pfizer-BioNTech COVID vaccine booster shot for all Americans aged 65 or older, as well as for those deemed to be at high risk for severe illness.

According to The New York Times, that vote came after a near unanimous decision (16 to 2) by the same independent panel of experts that sa...

In kids and teens, symptoms of long COVID rarely last more than 12 weeks, a new international study reports.

The researchers also found that exposure to the highly contagious Delta variant did not result in more serious disease in children compared to earlier variants, and that most cases of COVID-19 were asymptomatic or mild.

Despite those reassurances, the study did include a trou...

U.S. Food and Drug Administration advisors will meet Friday to consider whether it is safe and effective for Americans to receive a third "booster" dose of the Pfizer-BioNTech COVID-19 vaccine.

The FDA posted the materials it intends to use in the review on Wednesday. The advisory panel will review a variety of evidence, including new data from Israel, the Associated Press<...

Health officials are bracing for a viral double whammy this fall and winter.

"This year, we expect influenza and COVID-19 to circulate at the same time," said Dr. Jonathan Grein, director of hospital epidemiology at Cedars-Sinai in Los Angeles.

People with HIV have an increased risk of sudden cardiac death, a new study warns, especially if the virus isn't well-controlled.

Sudden cardiac death occurs when the heart unexpectedly stops beating, usually due to an abrupt electrical malfunction.

"People living with HIV are already known to have a higher risk of heart attack, stroke, heart failure, blood clots in the lungs and pe...

Monoclonal antibody infusions can help prevent severe COVID-19, but the best protection is to get vaccinated, experts say.

Antibodies are made by the immune system to fight infections.

"The problem is that our immune system takes two to three weeks to make good antibodies," said Dr. Turner Overton, co-director of the Alabama Vaccine Research Clinic at the University of Alabama at Bi...

A high amount of coronavirus in the lungs is a major contributor to death in COVID-19 patients, new research shows.

The findings challenge previous theories that simultaneous infections such as pneumonia or an overreaction of the body's immune system are significant factors in COVID-19 deaths, the researchers noted.

To come to that conclusion, the investigators analyzed bacterial an...

A common bug called respiratory syncytial virus (RSV) circulating among American kids during what's normally its off-season may cause concern if parents don't know how to tell it apart from COVID-19, experts say.

Unlike COVID-19, RSV is a long-established foe that normally emerges in late fall, peaks in the ...

COVID-19 vaccination triggers a strong immune response in people with HIV, meaning they're likely protected against the coronavirus, a new, small study shows.

"Previous research has suggested a suboptimal response to COVID-19 vaccines in people living with HIV; however, these studies did not fully characterize and define that response, both for cellular [where the immune system directly a...

Masks are making an unwanted comeback in many parts of the United States, after new data showing that fully vaccinated people with "breakthrough" coronavirus infections carry enough virus in their bodies to pose a potential risk to the unvaccinated.

But these breakthrough infections -- which have become slightly more common with the highly transmissible Delta variant -- pose little to no ...

People fully vaccinated with the Moderna COVID-19 vaccine appear to have a lower risk of a "breakthrough" infection caused by the Delta variant than those who received the Pfizer vaccine, a new, preliminary report suggests.

The researchers emphasized that both vaccines still "strongly protect" against severe illness, but the difference appears to be in the degree of pro...

A small, early study suggests that people who've already encountered SARS-CoV-2 may gain a big boost against COVID-19 if they get just one dose of the Pfizer vaccine -- and that protection may extend to new viral variants.

The study "supports the notion that vaccine effectiveness, even against emerging neutralization-resistant [variants], may be improved following an additional vaccine bo...

News that the highly contagious Delta variant of COVID-19 can be picked up and spread by vaccinated folks has sparked confusion and concern, and an infectious disease expert wants to clarify.

I think I've had COVID-19 already, so do I really need two doses of vaccine?

It's a question millions of people around the world are asking, and now a small, new study finds that people who know they were infected with SARS-CoV-2 in the past may need only one shot of the Pfizer vaccine to gain strong immunity.

In fact, "we observed higher SARS-CoV-2 antibody levels in previously in...

A little more than two out of every three people who have mild or moderate cases of COVID-19 will go on to develop long-term symptoms.

That's the troubling takeaway from a University of Arizona Health Sciences' study launched in May 2020.

"This is a real wake-up call for anyone who has not been vaccinated," said lead researcher Melanie Bell, a professor of biostatistics in the unive...

The two HIV prevention drugs available in the United States are equally safe and effective, and the biggest difference between them is price, a new study contends.

However, a sizable minority of patients have switched from the older and cheaper "preexposure prophylaxis" (PrEP) formulation to the newer and much pricier one. In many cases that switch might not have been warranted, the resea...

Go ahead, put your credit card away: Handling cash and coins isn't likely to give you COVID-19.
