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&#...

Dr. Anthony Fauci, the leading infectious disease expert in the United States, said on Wednesday he is "cautiously optimistic" that a COVID-19 vaccine will be ready by year's end.

Against the backdrop of a pandemic that has claimed over 220,000 American lives, Fauci noted that the United States' "strategic approach" to vaccine development appears to be bearing fruit. Six U.S. companie...

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...

Following weeks of delay, the White House on Tuesday approved tough new rules for coronavirus vaccine developers that will make it unlikely that a vaccine will be approved before Election Day.

The approval came only after the U.S. Food and Drug Administration published the updated guidelines on its website as part of briefing materials for outside vaccine advisers, the Washington P...

Facebook chatter from the anti-vaccination movement now frames the issue as one of civil liberties, a new study finds.

As a COVID-19 vaccine gets closer to becoming a reality, opposition from so-called anti-vaxxer groups could become a political movement, researchers warn.

For the study, the investigators looked at more than 250,000 posts on 204 Facebook pages opposing vac...

Everyone 6 months of age and older should get a flu shot this season, the American Medical Association (AMA) says.

With the coronavirus pandemic raging, a flu shot is more important than ever to protect yourself, your loved ones and your community from the flu.

"Routine vaccination is essential preventive care for children, adolescents and adults -- including pregnant women ...

Antibodies against COVID-19 in people who've recovered from the disease begin to vanish about three months after they develop symptoms, researchers say.

This suggests that sooner is better for recovered COVID-19 patients to donate antibody-containing blood plasma for convalescent plasma treatment, according to the authors of a small study published Oct. 1 in the journal Blood.<...

Despite a potential looming "twindemic" of influenza and COVID-19, about 2 in 5 U.S. adults do not plan to get a flu shot, a new survey shows.

Only 59% of adults surveyed said they will get the influenza vaccine during the 2020-2021 flu season, according to results released Thursday by the National Foundation for Infectious Diseases.

That's up slightly from the 52% w...

Girls who are vaccinated against human papillomavirus (HPV) may drastically cut their chances of developing cervical cancer by age 30, a huge, new study finds.

Researchers found that of more than 1.6 million young Swedish women, those who'd gotten the HPV vaccine were about two-thirds less likely to be diagnosed with cervical cancer than their unvaccinated peers.

Those odds ...

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...

People who buy into conspiracy theories about COVID-19 may be especially likely to refuse a vaccine when one becomes available, a new study suggests.

Researchers said the results are not surprising. But they highlight how mistrust in authorities could already be undermining efforts to get the pandemic under control: Those same conspiracy believers were also less likely to regularly we...

The best time to get your flu shot is now if you want to protect yourself against a potential "twindemic" infection of influenza and COVID-19, experts say.

"Early September, at the very least early October, is the best time to get your flu shot. That really allows your body to build up the appropriate immune response in time for the peak prevalence of influenza in the community," Dr. ...

Aches and fatigue quickly progressed to fever with severe chills, but the terrible and unrelenting headache was the real signal that actress Rita Wilson was in for a rough ride following her infection with COVID-19.

"It was a massive headache that really lasted for about two weeks," Wilson recalls. "It was relentless. It wasn't like Tylenol was making it go away or anything like that....

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, ...

More U.S. kids are getting a recommended vaccine that protects against several cancers -- but there is still much room for improvement, a new study finds.

At issue is the vaccine against human papillomavirus (HPV). Certain strains of HPV are sexually transmitted, and some of those are "high risk" -- meaning that if the immune system does not clear the infection, it can eventually lead...

While adults face raised odds for hospitalization with COVID-19, a new study shows that the risk for kids infected with SARS-CoV-2 is about equal to that seen with influenza.

The researchers found that kids with COVID-19 or the seasonal flu have similar rates of hospitalization, admission to intensive care units (ICUs) and ventilator use.

But the average age of children hosp...

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.

...

The U.S. Centers for Disease Control and Prevention is telling the nation to prepare for distribution of a COVID-19 vaccine this fall.

The CDC has notified public health officials across all 50 states that limited vaccine doses might be available by late October, and that they should prepare now as to how the vaccine will be routed to health care workers and other high-risk groups, ac...

Pregnant women are understandably worried about everything that goes into their bodies. But here's one worry they can cross off that list: flu shots.

A large, new study has confirmed that an expectant woman's flu shot doesn't increase the risk of autism in her child. And that's true even if the vaccine is given during the first trimester of pregnancy, the Swedish study found.

...

As many as 20% of Americans don't believe in vaccines, a new study finds.

Misinformed vaccine beliefs drive opposition to public vaccine policies even more than politics, education, religion or other factors, researchers say.

The findings are based on a survey of nearly 2,000 U.S. adults done in 2019, during the largest measles outbreak in 25 years.

The rese...

Flu and pneumonia vaccines lead to fewer hospital deaths among heart failure patients, a new study finds.

"Our study provides further impetus for annual immunizations in patients with heart failure. Despite advice to do so, uptake remains low," said study author Dr. Karthik Gonuguntla, of the University of Connecticut.

In heart failure, your heart can't pump blood as well as...

As the race to develop a safe and effective coronavirus vaccine unfolds around the globe, experts say the sheer logistics of vaccinating the masses might be even more daunting.

Scientists worldwide are racing to test and manufacture one or more coronavirus vaccines. But once a vaccine is proven safe and effective, one big question remains: How do you persuade everyone to take it?

Health experts have reason to worry.

Less than half of all American adults say they plan to get a COVID-19 vaccine when it becomes available, according to two recent polls...

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 ...

Fall is approaching, and so is the possibility of what public health officials are calling a "twindemic" -- overlapping epidemics of both COVID-19 and influenza.

A bad flu season coupled with continued COVID-19 outbreaks could increase people's risk of fatal illness and overwhelm hospital capacity in communities already scrambling to treat coronavirus patients, experts say.

...

Children can now be vaccinated by pharmacists in all 50 states as the U.S. government seeks to prevent a decline in routine vaccinations during the coronavirus pandemic.

While 28 states already allowed pharmacists to vaccinate children, the directive announced Wednesday by the U.S. Department of Health and Human Services (HHS) will temporarily override restrictions in 22 states starti...

A vaccine based on cutting-edge RNA gene technology showed promising potency against the new coronavirus in an early trial, scientists report.

The vaccine candidate -- for now just called BNT162b1 -- "elicited a robust immune response in participants, which increased with dose level and with a second dose," according to a news release from the journal Nature, which published th...

With coronavirus cases climbing in the United States, many parents are wary of taking their kids in for vaccinations, new research finds.

The survey of more than 700 parents by Orlando Health found that although 84% believe vaccines are necessary to protect their children from a host of diseases, two-thirds fear taking their kids to their doctor because of COVID-19.

Orl...

After the COVID-19 pandemic had millions of New Yorkers in lockdown, the rate of routine child vaccinations plummeted -- as it did in cities across the United States.

That had pediatricians worried that a second wave of illness outbreaks -- measles, whooping cough, mumps -- might follow as large groups of kids were left vulnerable.

But a new report from the nation's largest ...

An updated guideline from the American Cancer Society calls for more simplified cervical cancer screening, administered less often.

The new guideline calls for an initial cervix screening at age 25, followed by the human papillomavirus (HPV) test every five years, continuing through age 65, the guideline says.

"These streamlined recommendations can improve compliance and re...

More than a decade of research has shown that the human papillomavirus (HPV) vaccine protects against a host of cancers, yet a new study finds that only half of American teens complete the multiple-shot regimen.

Why? Researchers discovered that many parents still harbor safety concerns about the vaccine, even though it guards against 90% of all cervical and anal cancers.

<...

Vaccines remain a "remarkably safe" way to protect human health, thanks to a rigorous system of safety monitoring that continues after approval, a new review shows.

Ongoing safety monitoring led to safety-related label changes in 25 out of 57 vaccines approved by the U.S. Food and Drug Administration over a two-decade period, mostly related to the vaccine's effect on specific groups o...

Hospital patients at high risk for influenza had lower rates of death, heart attack, mini-stroke and cardiac arrest if they were vaccinated against flu during their hospital stay, a new study has found.

The study focused on certain groups at high risk for flu and its complications: those 50 and older, nursing homes residents, American Indians/Alaska Natives, and people with a chronic me...

Getting vaccinated to protect against pneumonia and flu may offer an unexpected benefit -- a lower risk of Alzheimer's disease, new research suggests.

Two new studies being presented Monday at this summer's virtual Alzheimer's Association International Conference found a lower incidence of Alzheimer's in people who got flu and pneumonia vaccines. A third study underscored the importa...

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...

Scientists who have identified the early smallpox strains used to create vaccines against the disease say this type of genetic research could help efforts to develop a vaccine against the new coronavirus.

Smallpox was among the most dangerous viral diseases in human history, killing about three of every 10 people who were infected. Many of those who survived were disabled, blind or di...

The highly anticipated results of two early-phase clinical trials of candidate COVID-19 vaccines suggest they are safe and may protect recipients, although the duration of the effect is still unknown.

"We are rapidly moving to an era in which a vaccine against the novel coronavirus is becoming a reality," noted Dr. Amesh Adalja, an infectious disease specialist and senior scholar at t...

As physical distancing, face masks and habitual hand-washing have become the new normal, hopes for returning to the old normal rest largely on the development of effective COVID-19 vaccines.

Historically, it has taken a decade or more to develop a vaccine. Yet some U.S. leaders say a vaccine for the new coronavirus could be ready as soon as late this year or early next.

Other ex...

A leading COVID-19 vaccine contender has passed its early safety trial with flying colors.

The vaccine, created by Moderna, produced an immune response in all 45 healthy participants who received two shots 28 days apart, according to findings reported July 14 in the New England Journal of Medicine.

The vaccine (named mRNA-1273 for now) uses messenger RNA, or mRNA, to ...

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.

A tuberculosis vaccine may help reduce the risk of death from COVID-19, researchers suggest.

Developing countries have lower-than-expected COVID-19 death rates, and a TB vaccine given in countries with high rates of tuberculosis might play a significant role in reducing COVID-19 death rates, according to authors of a new study.

The vaccine, which is routinely given to childr...

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...

Kids who have a fever-related seizure after getting a vaccine won't have developmental and behavioral problems as a result, according to a new study.

These so-called febrile seizures do not affect children's development whether they occur after a vaccination or not, the researchers said.

"A febrile seizure can occur following vaccination and understandably can be quite dis...

Top U.S. infectious disease expert Dr. Anthony Fauci warned Congress on Tuesday that COVID-19 infections could climb to 100,000 new cases daily unless ongoing outbreaks are contained.

"We are now having 40-plus thousand new cases a day. I would not be surprised if we go up to 100,000 a day if this does not turn around. And so I am very concerned," Fauci, director of the U.S. National ...

Animal studies of a potential COVID-19 vaccine have been so encouraging that researchers plan to speed up testing of the vaccine in humans.

Initially, the next phase of the trial was expected to begin in September, but that start date has now been moved to August.

Developed by researchers at the Duke-NUS Medical School in Singapore, the vaccine uses genetic material called m...

An experimental vaccine helps protect monkeys against bacteria that cause diarrhea in millions of children worldwide, researchers report.
