As the number of people fully immunized against COVID-19 rises into the hundreds of millions, immunologists and infectious disease experts now are pondering a new question in the unfolding pandemic.

Namely, how long will vaccine immunity last, and will people who've gotten the jab need booster shots to maintain their protection?

It's an important question, as waning immunity in the ...

After Texas relaxed COVID-19 restrictions, other respiratory illnesses -- such as colds, bronchitis and pneumonia -- made rapid rebounds.

Pathologists from Houston Methodist Hospital found that the rhinovirus and enterovirus infections that can trigger these illnesses started rebounding in the fall of last year after Texas eased capacity limits in bars and restaurants.

A real-world study shows that even when folks who get the Pfizer and Moderna COVID-19 vaccines do have 'breakthrough' infections, those illnesses are mild.

The study, from researchers at the U.S. Centers for Disease Control and Prevention, is among the first to show that people who get COVID-19 despite being fully or partially vaccinated are less likely to have serious illness or to infec...

It has been an elusive goal so far -- finding a potent treatment that can beat back the new coronavirus before it grabs a hold of a patient's immune system and sends it into overdrive.

But new research suggests that more than a dozen existing drugs or drugs under development may do the trick.

Investigators tested more than 12,000 drugs in two different types of human cells infected ...

In some good news for those who have already suffered through a bout of COVID-19, a new study finds they may have a much lower risk of reinfection for at least 10 months.

For the study, the researchers analyzed rates of SARS-CoV-2 infections between October 2020 and February 2021 among more than 2,000 nursing home residents (median age 86) and staff. Antibody testing was used to determine...

But, they say, given what's known about the human immune response to SAR...

MONDAY, May 24, 2021 (HealthDay News) – As researchers work to learn more about COVID-19 and so-called long-haulers, a new study suggests "brain fog" can persist and even worsen for those who were infected months before.

Long-haulers continue to have symptoms long after their COVID diagnosis, and these symptoms can be mental as well as physical.

"People have trouble problem-solvin...

A new coronavirus that appears to have jumped from a dog to a child has been discovered from a case three years ago, but it's unclear what threat it may pose.

This new canine-like coronavirus was found in a child in Malaysia in 2018. If it is confirmed as a human pathogen, it could be the eighth coronavirus known to cause disease in people.

The case suggests that transmission of cor...

Researchers have reported the first case of COVID-19 causing dangerous, recurring blood clots in a patient's arm.

The report offers new insight into how the damage of inflammation caused by COVID-19 can linger and how best to treat recurring clots, the Rutgers University researchers said.

There have been reports of lower extremity blood clots in patients after COVID-19, but this is ...

New insight into a rare and dangerous disorder that can occur in kids with COVID-19 could improve treatment of the condition, researchers say.

Four in 10 transgender women have HIV, which shows the urgent need to offer them more prevention and treatment services, according to a new U.S. Centers for Disease Control and Prevention report.

In interviews with more than 1,600 transgender women in Atlanta, Los Angeles, New Orleans, New York City, Philadelphia, San Francisco and Seattle in 2019 and early 2020, researchers found that 42...

In very rare cases, children infected with the new coronavirus can develop a severe illness known as multisystem inflammatory syndrome (MIS-C). Now, research finds that these young patients often develop neurologic symptoms along with the respiratory issues they might face.

These neurologic symptoms were present in half of children who were hospitalized with MIS-C, U.K. researchers say.

Two new studies out of Britain find that although the now-dominant "U.K. variant" of the new coronavirus does spread more quickly, it does not appear to lead to more severe disease in those made ill.

The findings should help allay fears that more patients will die after infection with the variant, officially labeled B.1.1.7.

Scientists published the findings online April 12 in two<...

COVID-19 might have a tough new foe: The sun.

New research shows that sunnier regions of the United States have lower COVID-19 death rates than cloudier areas, suggesting that the sun's UV rays might somehow provide some protection against the disease.

The effect is not due to better uptake of the healthy "sunshine vitamin," vitamin D, noted the Scottish research team led by Richard...

Two COVID-19 vaccines appear to work well against a rapidly spreading coronavirus variant that arose in California, but less effective against a variant that first emerged in South Africa, researchers report.

"The good news is the California variant does not appear to be a problem for our current vaccines," said study author David Montefiori, director of the Laboratory for AIDS Vaccine Re...

Two people in the Johnson & Johnson COVID-19 vaccine trial developed Guillain-Barré syndrome, but it's highly doubtful the vaccine is to blame, according to a just-published case study.

Although both people were in the same trial, one was given the vaccine and the other was given a placebo of saline solution.

"That strengthens the possibility that the case in our report may have be...

COVID-19 is so contagious that even a single breach of social distancing measures can have far-reaching consequences.

A case in point: An explosion of new COVID-19 cases traced to five people who joined in on a bar's opening night in rural Illinois in February.

Four of the five who attended the crowded gathering (the bar's capacity was 100 people) were already experiencing symptom...

There's good news for the millions of Americans who've already received a dose or two of Moderna's COVID-19 vaccine: New research shows the vaccine should protect against illness for at least six months.

The new study tracked 33 participants in the trials that led to the vaccine's approval. Six months after having received their second vaccine dose, "antibody activity remained high in al...

Because of the COVID-19 pandemic, scientists thought twice about studying North American bats in their winter habitats. But they've now determined that the risk of humans passing the coronavirus to bats under these conditions was low.

The U.S. Geological Survey (USGS) led the study. It found the risk to be one in 1,000 with no protective measures and one in 3,333 with proper use of per...

Kids will be kids, and that's exactly why Holly McDade plans to get her three young children the COVID-19 vaccine as soon as it becomes available to them.

"Little kids can't help but touch their mouths and their noses and touch other things," said McDade, 32, of Strasburg, Va. "They just don't think about it. It's not where their brains are at yet."

McDade isn't concerned so much ab...

It's the question everyone wants answered because reopening the world depends on it: Can coronavirus vaccines stop transmission of the virus?

Now, 21 universities across the United States are teaming up to find out.

It's very rare, but it is possible to catch COVID-19 even if you've been vaccinated, a new study finds.

Looking at vaccinated health care workers at two University of California campuses, researchers found a tiny number tested positive for the virus. This finding highlights the need to keep wearing a mask and to keep social distancing, the researchers said.

"Because of the compulso...

COVID-19 transmission is rare in schools that follow precautions such as mandatory masks, social distancing and frequent hand-washing, a new study finds.

And that's true even among close school contacts of people who test positive for the new coronavirus, according to researchers at Washington University School of Medicine in St. Louis.

"Schools can operate safely during a pandemic ...

Yet another organ seems to be affected by a bout of COVID-19: the thyroid.

Italian researchers have examined the thyroids of dozens of patients who've recovered from moderate-to-severe cases of COVID-19. The study found evidence that SARS-CoV-2 infection may trigger an inflammation of the gland in some patients.

Whether that inflammation can cause long-term dysfunction is still unc...

Poorly controlled type 1 diabetes significantly increases a child's risk of COVID-19 complications and death, researchers warn.

The risk of complications is 10 times higher in youngsters with poorly controlled type 1 diabetes than in those with well-controlled diabetes, according to a study presented Saturday at a virtual meeting of The Endocrine Society.

"This study shows keeping d...
