People in nursing homes have been suffering in isolation during the coronavirus pandemic, with their institutions in constant lockdown to prevent potentially fatal outbreaks.

Now that they're some of the first in line to receive COVID-19 vaccinations, it would be natural for nursing home residents to expect that visits from friends and family will soon resume.

That might not happen,...

Now that federal guidelines have expanded COVID-19 vaccine eligibility to include people over 65 and those of all ages with underlying health conditions, drug stores say they are ready, willing and able to start giving the shots.

There's just one slight glitch: supply. But with two vaccines already available and others moving toward emergency use authorization, experts say supply will lik...

The United States has far fewer flu cases than normal, and experts say it's probably due to measures people are taking to protect themselves from COVID-19.

Flu season usually peaks between December and February. Influenza typically causes about 45 million illnesses, 810,000 hospitalizations and 61,000 deaths in the United States each year, according to the U.S. Centers for Disease Control...

The bad news? COVID-19 may be around for a long, long time. The good news? Even if it does, new research suggests it could very well end up being just another mild illness, bringing with it inconvenience and discomfort, but rarely hospitalization or death.

Why? The theory is rooted in the epidemiology patterns previously followed by four other coronaviruses. All have been in circulation f...

Folks who've gotten through a COVID-19 infection might naturally question whether they need to get a coronavirus vaccination when their turn comes.

Experts say they really need the shot anyway, because even after having COVID they might be vulnerable to reinfection.

"We're encouraging people if they meet the other criteria to get immunized because we don't know how long either natur...

Concerns about "long-haul" symptoms in COVID-19 survivors may be reignited by a new study: It finds that 3 out of 4 patients from Wuhan, China -- where the pandemic originated -- were still suffering at least one lingering health problem six months later.

The study from China involved more than 1,700 patients first diagnosed with the virus in Wuhan between January and May, and then follo...

A task force of allergists and immunologists recommends those administering the COVID-19 vaccine ask patients some key questions beforehand.

While reactions to vaccines are extremely rare, the American College of Allergy, Asthma and Immunology (ACAAI) said anyone being vaccinated should be asked if they have a history of a severe allergic reaction ...

President-elect Joe Biden plans to release nearly all available doses of COVID-19 vaccine when he takes office, reversing the Trump administration's strategy of holding back half the supply to ensure second doses are available.

The potentially risky move is meant to boost a nationwide COVID-19 vaccination program that has gotten off to a slow start, with only about 5.9 million doses admin...

As Americans await their COVID-19 shot, a new study of a different vaccine shows the power of Facebook posts in fueling "anti-vax" resistance to immunization.

The study included more than 10 years of public Facebook posts on the human papillomavirus (HPV) vaccine. It found that nearly 40% of 6,500 HPV vaccine-related posts from 2006 to 2016 amplified a perceived risk. The data suggest the...

Cases of anaphylactic shock caused by COVID-19 vaccines are very rare, based on numbers from the first week and a half of vaccinations in the United States, federal public health officials said Wednesday.

There have been 21 cases of anaphylaxis out of nearly 1.9 million doses of the Pfizer-BioNTech vaccine administered in the very first days of the national COVID-19 vaccination program, s...

A return to normal life in America might happen sooner than many expect, one of the nation's leading vaccine experts told HD Live! this week.

As the new coronavirus rages across the country, President-elect Joe Biden has set a goal of one million doses of vaccine delivered every day once he takes office. If that ambitious target is realized, everyday conditions in the United States might ...

By Nov. 15 of last year, roughly 47 million Americans -- about 14.5% of the U.S. population -- had already been infected with the new coronavirus, a new study finds.

That's much higher than the close to 11 million known U.S. cases of infection that were recorded by that date, the researchers said, because reported cases "do not represent the full SARS-CoV-2 disease burd...

In late December, Dr. Ada Stewart asked her staff to check on a patient who had missed an appointment.

She soon learned that the patient had no transportation for the 45-minute drive, so Stewart offered to conduct the appointment by phone instead.

"It still accomplished so much. I was able to see how their diabetes was doing, how they were preparing for the holiday seaso...

THURSDAY, Dec. 31, 2020 -- Folks who contract COVID-19 can expect to gain some durable immunity against future infection, according to a new study of memory cells within the immune systems of coronavirus patients.

Previous studies have raised concern that COVID-19 patients might lose their immunity quickly once they recover, because the first wave of coronavirus antibodies tends to wane a...

In very rare cases, some people have had severe allergic reactions after receiving the new COVID-19 vaccines, leading the American College of Allergy, Asthma, and Immunology (ACAAI) to issue updated guidance for Americans with allergies.

The U.S. Food and Drug Administration has given emergency use authorization to COVID-19 vaccines from Pfizer-BioNTech and Moderna.

The ACAAI's COVI...

There's a lot of misinformation about vaccines as the United States begins its massive COVID-19 vaccination program, so an expert wants to dispel the many myths about vaccines in general.

Vaccines are among the most heavily studied of all drugs, and the evidence shows they are safe and extremely effective, according to Dr. Patrick Gavigan, a pediatric infectious disease physician at Penn ...

Though many Americans would support a COVID-19 vaccine mandate, a Gallup survey finds there is no clear majority in favor of it.

The Gallup Panel conducted the online survey of 2,730 U.S. adults between Sept. 14 and 27.

Nearly 49% of respondents said they would "accept" a state mandate requiring children to be vaccinated in order to attend school. But support fell to 41% when respo...

Amid hopes stirred by the recent rollout of an approved COVID-19 vaccine in the United States, a new study warns that shots may not be available to nearly one-quarter of the world's people until 2022.

A second study estimates that 3.7 billion adults worldwide are willing to get the vaccine.

Together, these two findings suggest that getting people immunized could be as big a challen...

As America rolls out a nationwide coronavirus vaccination campaign this week, experts help answer your questions about the new COVID-19 vaccines.

Both the Pfizer vaccine (already approved by the U.S. Food and Drug Administration) and the Moderna vaccine (up for approval) were developed using a technology called messenger RNA, or mRNA, explained Dr. Thomas Ma. He's chair of the department ...

More than 15 million Americans have been infected by the COVID-19 virus, and many may be questioning whether they need to receive one of the two coronavirus vaccines now on the verge of approval from U.S. regulators.

Short answer: Yes.

"They will be asked to stand in line and get a vaccine also," said Dr. William Schaffner, a professor of infectious diseases at Vanderbilt University...

Getting a high-dose flu shot instead of a regular dose doesn't further reduce the risk of serious flu-complications, hospitalization or death in people with heart disease, new research shows.

The findings don't change established guidelines. Heart disease patients and other people with chronic illnesses do benefit from flu shots and should get one every year, according to the authors...

Two new COVID-19 vaccines, developed at record-setting speed, are soon to be assessed by U.S. agencies for emergency use in combating the ongoing pandemic.

Advisory panels of infectious disease experts this week will assess a vaccine developed by pharmaceutical company Pfizer and German biotech firm BioNTech -- a vaccine that Britain began administering to its most vulnerable citizens on ...

AstraZeneca's COVID-19 vaccine is safe and effective, new data from late-stage trials shows.

Overall, the vaccine protected against symptomatic disease in 70% of cases, according to a team led by researchers from Oxford University in England. Among study volunteers who got a half dose and then a full dose, the rate was 90%, while the rate was 62% in those given two full doses.

A stronger immune system and healthier blood vessels are among reasons kids are less likely than adults to have severe COVID-19, according to experts who reviewed research from around the world.

"Most children with COVID-19 have no or only mild symptoms, most commonly fever, cough, sore throat and changes in sense of smell or taste. Even children with the usual risk factors for severe inf...

Scientists say they may be getting closer to creating a universal flu vaccine.

In an early-stage clinical trial with 65 volunteers in the United States, an experimental vaccine triggered strong immune responses to a wide range of flu virus strains and subtypes. The immune responses lasted at least 18 months, according to the researchers at Mount Sinai Health System, in New York City.

A widely used tuberculosis vaccine may help protect people against the new coronavirus or reduce the severity of COVID-19, a new study suggests.

The Bacillus Calmette-Guérin (BCG) was developed in the early 1900s and is given to more than 100 million children worldwide every year.

In the United States, BCG is approved as a vaccine for people at high risk of contracting tuberculosis...

As scientists worked on COVID-19 vaccines, other researchers were addressing a question: Once shots are available, will parents vaccinate their kids against the new coronavirus?

The answer: Younger parents are much less likely than older ones to plan to vaccinate their children and themselves against COVID-19.

"Parents' willingness to vaccinate themselves and their children against ...

A Chinese COVID-19 vaccine seems to be safe and effective, early trial results suggest, but one expert says the findings should be regarded with caution.

The CoronaVac vaccine is based on inactivated SARS-CoV-2 virus. It was tested in a phase 1/2 clinical trial that included more than 700 healthy volunteers, ages 18-59, who were recruited in China between April 16 and May 5.

The vac...

Immunity to the new coronavirus may last six months or longer after people recover from infection, a new study suggests.

Researchers collected blood samples from 149 patients who had COVID-19 early in the pandemic and analyzed them for immune cells that make antibodies that block the SARS-CoV-2 virus from entering cells.

One month after infection, all of the patients had coronavirus...

Scientists are reporting early success with an experimental herpes vaccine that uses a genetically modified version of the virus.

The gene edit prevents the virus from performing its normal evasive maneuver: hiding out in nervous system cells in order to elude the immune system.

So far, the vaccine has only been tested in lab animals. But scientists hope the genetic tweak will ...

Early COVID-19 vaccine trial results announced by Pfizer this week caused hopes to soar for a swift end to the pandemic that has killed more than 242,000 and infected more than 10 million in the United States alone.

But even if the preliminary results released Monday pan out, it will still take many months to produce enough of the vaccine to inoculate everyone in the United States, expert...

Nearly one in five American parents described themselves as "hesitant about childhood shots" in 2019, a new U.S. government study finds.

That was fewer than the one in four who expressed hesitancy about vaccines in 2018.

The new research found real consequences from vaccine hesitancy. Rates of flu vaccination were 26 percentage points lower in children of "vaccine-hesitant" parents ...

When scientists finish developing a COVID-19 vaccine, will people be willing to take it?

An international research team analyzed data from 19 countries hit hard by the new coronavirus and found that when confidence in government was low, hesitancy to accept a COVID-19 vaccine was higher.

Based on a previous survey of more than 13,400 people, researchers found that about 72&#...

Promoting any emerging COVID-19 vaccine to a skeptical public could be tough.

But a new survey finds vaccine uptake might rise if the shot is promoted by medical experts, not politicians, and if it's been proven safe and effective through a rigorous approval process.

A vaccine shown to be highly effective in clinical trials with lasting protection and rare major side effects...

An experimental COVID-19 vaccine appeared to be safe and triggered an immune response in healthy people, according to preliminary results of a small, early-stage clinical trial.

The study of the vaccine based on inactivated whole SARS-CoV-2 virus (BBIBP-CorV) included more than 600 volunteers in China, ages 18 to 80. By the 42nd day after vaccination, all had antibody responses to the...

When parents have concerns about the safety of childhood vaccinations, it can be tough to change their minds, as a new study shows.

The study involved "vaccine-hesitant" parents -- a group distinct from the staunch "anti-vaxxer" crowd. They have worries about one or more routine vaccines, and question whether the benefits for their child are worthwhile.

Even though those par...

After a serious case of COVID-19 you may have long-lasting immunity, a new study finds.

The finding is reassuring to patients because the immune system makes antibodies in response to SARS-CoV-2, the virus that causes COVID-19, the researchers said.

"But there is a big knowledge gap in terms of how long these antibody responses last," said researcher Dr. Richelle Charles o...

One of the big questions around any new COVID-19 vaccine is: Will it safely protect those at highest risk from the illness -- older people?

Now, the results of an early phase 1 trial in 40 adults over the age of 55 suggests that one vaccine, under development by drugmaker Moderna, elicits an immune system response that's equal to that seen in younger recipients.

As well, vac...

The coronavirus pandemic and the upcoming flu season could pose a double threat, but many U.S. parents plan to skip flu shots for their kids, a new survey finds.

Though public health experts stress the need for people of all ages to get the seasonal flu vaccine during the COVID-19 pandemic, 1 in 3 U.S. parents said they don't plan on taking their child for a flu shot this fall. Just a...

Low blood levels of vitamin D might heighten people's odds for severe or even fatal COVID-19, new research shows.

Taking in a healthy level of vitamin D may therefore "reduce the complications, including the cytokine storm [release of too many proteins into the blood too quickly] and ultimately death from COVID-19," said study author Dr. Michael Holick. He's a professor of medicine, p...

Parents who choose to forgo or delay their children's vaccinations may quickly find themselves without a pediatrician.

Just over half (51%) of pediatric offices in the United States have a policy to dismiss families that refuse childhood vaccines, a nationwide survey found. Thirty-seven percent of pediatricians themselves said they often dismissed families for refusing vaccines, ...

Key differences in immune system function may help determine why severe, life-threatening COVID-19 tends to target older men, scientists say.

A new study found that among elderly people and in men, especially, certain factors may lead to a weaker immune system response against infection with SARS-CoV-2, the virus that causes COVID-19.

That could help explain high rates of in...

A new clinical trial will try to determine whether the measles, mumps and rubella (MMR) vaccine can protect health care workers from being infected with COVID-19.

Hundreds of millions of people have received the MMR vaccine since it was developed nearly 50 years ago. It's usually given to children before age 6. Growing evidence suggests that the vaccine may also prevent COVID-19.

...

Since the pandemic began, it's been clear that men are more vulnerable to getting a severe case of COVID-19 compared to women.

Now, researchers say they've uncovered significant differences in how male and female immune systems respond to the new coronavirus may help explain why men are more likely than women to have severe COVID-19 and to die from the illness.

Worldwide, me...

Despite the wave of criticism that has followed the U.S. Food and Drug Administration's emergency approval of convalescent plasma to treat COVID-19 patients, infectious disease experts say the therapy remains promising.

Some scientists have questioned both the timing of the approval and the veracity of a key survival statistic cited by FDA Commissioner Dr. Stephen Hahn. And the clinic...

When elementary school students get their annual flu shot, everyone benefits, a new study shows.

An increased vaccination rate among grade schoolers in California was associated with a decrease in flu hospitalizations for folks in every other age bracket, researchers report.

The results come as no surprise to public health experts, given children's well-earned reputation as ...

Since the pandemic began, it's been known that the severity of coronavirus illness varies widely between people. Could the common cold be the reason why?

It's still just a theory, but researchers in California suspect that if you've recently had a cold -- many of which are also caused by coronaviruses -- your immune system's T-cells might recognize SARS-CoV-2 and help fight it.

...

Hopes for robust, long-term antibody protection after a bout of COVID-19 have been dampened by a new study that finds the protection may only last a few months.

Still, experts noted that the body's immune system has more than one way to defend against viruses it has already encountered, so the findings don't dash hopes for a vaccine.

"Infection with this coronavirus does not...

With several potential COVID-19 vaccines now in clinical trials, U.S. policymakers need to plan for the next hurdle: Ensuring Americans actually get vaccinated.

That's according to a new report from the Johns Hopkins Center for Health Security. It lays out recommendations for winning the public's trust of any future vaccine, and helping them access it as easily as possible.

...

Even the sickest COVID-19 patients make T-cells to fight the infection, a new study finds.

This means that a COVID-19 vaccine will have to cause the body to make T-cells along with antibodies, researchers say.

The immune response to the SARS-CoV-2 virus, which causes COVID-19, was the same in American and Dutch patients in the study.

"You want vaccine approaches...
