In a finding that could help guide the response to the coronavirus pandemic, new research shows that a measles outbreak that struck New York City last year could have been much worse if the city had not launched a vaccine campaign.

The measles outbreak -- the largest in the United States in nearly three decades -- ultimately sickened 649 people. Most were children in a Brooklyn Orthod...

Even if a vaccine against the new coronavirus is developed, only half of Americans say they'd get it, a new survey finds.

It also found that 31% weren't sure if they'd get vaccinated, and about 1 in 5 said they wouldn't get vaccinated.

Of those who'd refuse a vaccine, 7 in 10 cited safety concerns, according to the Associated Press-NORC Center for Public Affairs Rese...

Another COVID-19 vaccine candidate has achieved good early results, a research team in China reported Friday.

The experimental vaccine produced important signs of immune response in a small group of adults, a sign that it could potentially protect people against COVID-19, researchers reported May 22 online in The Lancet medical journal.

"These results represent an imp...

Two new studies offer hope for an effective coronavirus vaccine -- and for the notion that prior infection also confers immunity.

Both studies were conducted in rhesus macaque monkeys, so testing in humans is required for more definitive proof. But in one study, monkeysdeveloped immunity against the new SARS-CoV-2 coronavirusafter receivingexperimental vaccines.

"Our finding...

Groups that spread vaccine misinformation on social media have more impact than government health agencies and other expert organizations on undecided people, a new study finds.

The spread of false information could have significant public health consequences if an effective COVID-19 vaccine is developed, the researchers noted.

For the study, investigators developed an innov...

An experimental vaccine seems to give monkeys extended protection from an HIV-like infection -- by "waking up" an arm of the immune system that vaccines normally do not.

Experts cautioned that animal research often does not pan out in humans. The decades of work toward an HIV vaccine has been a clear example. But, researchers said, this vaccine works differently, targeting two "arms" ...

Efforts to create a COVID-19 vaccine are proceeding at an unprecedented pace, with eight different candidates now being tested in humans around the world.

But to have a vaccine available for widespread use by early next year could entail bending some rules regarding safety and testing -- actions that might put the health, and possibly the lives, of test volunteers at risk.

Fear of exposure to COVID-19 appears to be exacting an unexpected toll on public health: Childhood vaccination rates have plummeted, leaving millions at risk for other life-threatening illnesses.

"We're seeing a general drop in pediatrician visits of 70% to 80% -- and that's very concerning," said Dr. Sara Goza, president of the American Academy of Pediatrics (AAP). She added ...

A new oral polio vaccine promises to help make polio a disease of the past, according to the results of a phase 1 clinical trial.

Polio was almost eliminated worldwide -- except in vaccine-induced cases. In those cases, the weakened virus used in vaccines developed the ability to escape from immunized individuals and spread in places with low vaccination rates.

The new des...

Vaccines for measles, mumps, rubella and varicella (chickenpox) are highly effective and do not cause autism, say researchers who reviewed 138 studies that included 23 million children.

"In terms of safety, we know from previous studies all around the world that the risks posed by these diseases far outweigh those of the vaccines administered to prevent them," said lead author Dr. Car...

Public health officials have been warning that a COVID-19 vaccine will not be available to the public for 12 to 18 months, dampening hopes that there will be a quick end to the global pandemic nightmare.

But Chinese researchers cracked the virus' genetic code within weeks of its emergence late last year, and two vaccine candidates are already in early human...

Yet another potential vaccine against the new coronavirus is in early development -- one that researchers say could be rapidly made and distributed if it proves effective.

The vaccine has only been tested in lab mice, but it's able to spur the animals' immune systems to produce antibodies against the coronavirus that causes COVID-19.

Researchers at the University of Pittsbur...

Social media is rife with misinformation about the safety of vaccines, according to a new study.

Lead researcher Lucy Elkin's team found that false claims about vaccines are readily available on Google, Facebook and YouTube despite efforts to control access to misinformation through computer programming and policy changes.

Work is proceeding apace on a "universal" flu vaccine capable of protecting humans from all forms of influenza, researchers report.

A single dose of a synthetic universal flu vaccine called FLU-v appears capable of providing safe long-term protection across a broad spectrum of influenza viruses, a new clinical trial has shown.

FLU-v outperformed a placebo in elevating peopl...

A Harvard/China collaboration has entered the coronavirus COVID-19 fray, with researchers on both sides of the globe working to expand understanding of the potentially pandemic virus.

The researchers will be working on vaccines to prevent infection and antivirals to treat the sick, but the effort is a more holistic approach designed to figure out the basic biology of the virus and how...

Vaccines protect you and your family against a number of diseases, so it's crucial to keep them updated, health experts say.

"It's important to review your vaccination records with your health care provider," said Libby Richards, associate professor of nursing at Purdue University in West Lafayette, Ind. "Vaccinations aren't just for kids. Adults need them, too."

Which shots...

Countering a U.S. government advisory, a new study suggests that adults may not need regular booster shots for tetanus and diphtheria if they received a complete vaccination series as children.

Researchers compared data gathered from millions of people in 31 countries in North America and Europe between 2001 and 2016. They found no significant differences in rates of the two diseases...

Nearly 1 in 5 American adults has mistaken beliefs about vaccines, and misinformation is more common among those who rely on social media than on traditional media, a new study finds.

Researchers surveyed nearly 2,500 adults nationwide in the spring and fall of 2019, when the United States was dealing with its largest measles outbreak in decades, and found that up to 20% of respon...

It's been overshadowed by the new coronavirus outbreak in China, but this year's flu season could be near its peak after surging throughout the United States for months.

At least 14,000 people have died and 250,000 have already been hospitalized during the 2019-2020 flu season, according to estimates from the U.S. Centers for Disease Control and Prevention. More than 26 million Americ...

Young men who have sex with other men don't fully grasp their risk for human papillomavirus (HPV) infection, due to a lack of information from health care providers, researchers say.

Interviews with men in their early 20s who are gay, bisexual or who identify as straight but have sex with men found that they knew little about HPV, including how it is transmitted, its symptoms and how ...

Though a severe flu season is now in full swing in the United States, a new government report delivers a bit of good news: This year's vaccine is working well against the viruses that are circulating.

"Preliminary vaccine effectiveness estimates indicate that the 2019-20 flu vaccine is providing substantial protective benefit, particularly among children, who were hard hit by flu this...

There's been a crucial move forward in efforts to develop vaccines and treatments against the new COVID-19 coronavirus, U.S. researchers say.

As of Wednesday, cases of infection with the virus have topped 74,000 (the vast majority in China), including more than 2,000 deaths. Therefore, a quick path to a vaccine and effective antiviral treatment is being sought by scientists worldwide....

Hepatitis, appendicitis and viral meningitis are among the serious complications that can occur when you get the measles, doctors warn in a new report.

The study -- which outlines cases involving three adults who developed major complications -- is also a reminder of the importance of vaccination against the illness.

Measles is highly contagious, but it's also easily prevent...

Scientists say that 90% of dengue cases could be slashed by artificially infecting mosquitoes.

Dengue viruses are spread to people by infected mosquitoes. But infecting the insects with Wolbachia bacteria blocks the dengue virus from replicating in mosquitoes and being transmitted between people, the international researchers said in a new study.

Wolbachia is found natur...

Seniors who get the shingles vaccine may gain stroke protection as well, a new study suggests.

Shingles is a viral infection tied to heightened risk of stroke. But overall stroke risk dropped 20% among patients under age 80 who got the shingles vaccine. In patients 80 and older, risk was cut by about 10%, said researchers led by Quanhe Yang, a senior scientist at the U.S. Cent...

A single dose of the human papillomavirus (HPV) vaccine works as well as multiple doses to protect older teen girls against preinvasive cervical disease, which can develop into cervical cancer, researchers say.

For the study, the researchers analyzed data on more than 133,000 females aged 9 to 26. Half weren't vaccinated and half received one or more HPV vaccine doses between January...

Vaccination and screening could nearly wipe out cervical cancer in North America in the next 20 years and rid the world of the disease within the next century, researchers say.

A mad dash is afoot to craft a vaccine for the new coronavirus that's ravaging China and starting to spread across the globe, with possibly dozens of labs working on permanent protection against the pathogen.

Researchers say an effective vaccine could be created in a matter of weeks, using advanced techniques.

"We know enough. We can do this. We can actually make a vaccine i...

This flu season is hitting children particularly hard, but new research shows that a flu shot is still well worth it for these youngest patients.

Getting vaccinated halved the risk of hospitalization for flu-related complications among young kids, scientists found.

The researchers analyzed vaccination data from more than 3,700 children, ages 6 months to 8 years, who were adm...

An examination of vaccination trends in Denmark shows just how damaging vaccine misinformation can be.

From 2013 to 2016, negative information about the HPV (human papillomavirus) vaccine spread widely through Danish media outlets. As a result, thousands of girls did not receive the vaccine.

For the study, researchers from the University of North Carolina at Chapel Hill look...

Sepsis kills more than twice as many people worldwide as once believed, and children in poor regions account for an excessive number of such deaths, researchers say.

Sepsis is an out-of-control immune response to infection that harms organs. People who survive sepsis can have lifelong disabilities.

In 2017, there were 48.9 million cases of sepsis and 11 million sepsis deaths...

Millennials are less likely to have had a flu shot this season and are more likely than other American adults to agree with some false anti-vaccination information, according to a new nationwide survey.

The results also showed that nearly one-third of adults polled don't plan to get a flu shot and many underestimate how deadly flu can be.

The American Academy of Family Phys...

An experimental flu vaccine gave mice long-lasting protection against six different flu virus strains, researchers report.

The nanoparticle vaccine contains two major influenza proteins -- matrix protein 2 ectodomain (M2e), and neuraminidase (NA) -- and protected the mice for up to four months.

The results suggest that this combination has potential as a universal flu vaccin...

HIV infection causes a loss of immunity to smallpox, even in people who were vaccinated as kids and are taking antiretroviral drugs to restore their immune system, a new study finds.

Such "HIV-associated immune amnesia" could explain why people with HIV who are on antiretroviral therapy still have shorter lives on average than people without HIV, according to the researchers.

So far the CDC estimates th...

In a finding that might make the HPV vaccine more palatable to many, new research suggests a single dose may provide just as much protection from cervical cancer as the recommended two to three doses do.

"The vaccine is extremely effective, and can prevent over 90% of nearly 35,000 cancers caused by HPV every year among men and women," explained study author Ashish Deshmukh. He's ...

An experimental Zika virus vaccine that was given before pregnancy protected monkey fetuses, researchers say.

The Zika DNA vaccine VRC5283 lowered levels of Zika virus in pregnant rhesus macaques and reduced the risk of fetal problems, according to the study published Dec. 18 in the journal Science Translational Medicine.

The vaccine is in early-stage human trials.

If new research is any indication, tougher vaccine exemption laws work.

After California eliminated nonmedical exemptions from vaccinations in 2016, the number of children receiving recommended immunizations rose -- especially in counties where "vaccine hesitancy" runs high, a new analysis found.

The policy -- passed in response to outbreaks of measles and other "old" childh...

As an early flu season spreads its misery across the United States, new research shows that few child care centers require children or their adult caregivers to get a flu shot.

Flu can be especially dangerous for children, who have a greater risk than adults for serious complications, hospitalization and even death, the researchers noted.

"When ki...

The first Ebola vaccine approved by the U.S. Food and Drug Administration is a single-dose injection called Ervebo.

The vaccine from Merck & Co. is approved to protect against the Zaire ebolavirus in people 18 and older.

In the United States, Ebola infections are rare. Confirmed cases have involved people in other countries who became infected and then traveled to...

A special dye that's injected at the time of vaccination could become an alternative to paper or electronic vaccination records, researchers report.

"In areas where paper vaccination cards are often lost or do not exist at all, and electronic databases are unheard of, this technology could enable the rapid and anonymous detection of patient vaccination history to ensure that every chi...

The flu season is off to a fast and furious start, with a strain of the virus that normally arrives later in the season making a strong early appearance, U.S. health officials said Friday.

Flu is now widespread across many parts of the country, said Lynnette Brammer, leader of the domestic influenza surveillance team at the U.S. Centers for Disease Control and Prevention.

"My job and having young children mean exha...

A surprising new study upends the notion that antibodies passed from mother to fetus protect infants from measles for as much as a year.

In fact, infants' immunity wanes much more rapidly than once thought, researchers report in the December issue of Pediatrics. The finding drives home the importance of community-wide immunizations.

"Measles is a serious disease, p...

Outbreaks of vaccine-preventable diseases are on the across rise in the United States, often fueled by "anti-vaxxer" parents reluctant to immunize their kids.

However, states are countering these trends with laws to boost childhood vaccination rates and safeguard children, a new study finds.

"Vaccines are our best public health tool for controlling many childhood diseases," ...

The HPV vaccine gives parents a chance to prevent their children from developing some types of cancer, and two new studies reaffirm what past research has found -- the vaccine is safe.

The two studies included millions of doses of Gardasil 9 vaccine, the only vaccine currently used in the United States for the prevention of HPV-related cancers.

"The data from our study was...
