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.

Bacterial gastroenteritis -- a digestive problem associated with malnutrition among millions of children younger than age 5 each year in developing nations -- can be caused by Campylobacter bacteria. Repeated infections can stunt growth and ...

Wondering whether stay-at-home advisories mean you should skip your child's check-up? According to one pediatrician, parents should keep their kids' regular health appointments during the coronavirus pandemic.

"I'm having these conversations every day with my patients," said Dr. Mona Patel, an attending physician in the division of general pediatrics at Children's Hospital Los Angeles...

There's no vaccine for COVID-19 yet. But there are routine immunizations that people aren't getting for a host of debilitating and potentially deadly diseases.

In May, the Centers for Disease Control and Prevention reported sharp drop-offs beginning in mid-March for pediatric vaccines ordered and given. And the World Health Organization estimated up to 80 million babies globally were mi...

One-quarter of U.S. parents are hesitant about seasonal flu shots for their kids, and roughly 1 in 15 feel the same way about routine childhood vaccinations, a nationwide study finds.

The issue has gained added urgency this year, as fears around coronavirus keep many parents from bringing their kids to the doctor -- including routine vaccinations.

Twelve percent of the nearl...

Americans are ready to rip off their face masks and just have a nice dinner in a restaurant, but the best shot at returning to normalcy -- vaccines to prevent COVID-19 -- will be in clinical trials for months or longer.

The good news is that there are more than 100 vaccines of varying types and in various stages of development. As of this month, eight of these vaccine candidates were...

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.

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.
