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...

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...

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.

In a new study, the researchers assessed the potential impacts of the World Health Organization's (WHO) draft strategy for cervical cancer elimination, which calls for 90% of girls to be vaccinated against ...

Some simple precautions can protect you and others, said Libby Richards, an associate professor who specializes in public health at Purdue University School of Nursing in West Lafayette, Ind.

"If you are sick or a family member or friend you are planning on visiting for a Super Bowl gathering is sick ...

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.

<...

The tuberculosis (TB) vaccine is far from infallible, but new animal research suggests the problem is not the vaccine but how it is delivered.

When given to monkeys intravenously rather than as an injection, the vaccine was much more effective, researchers from the University of Pittsburgh and the U.S. National Institute of Allergy and Infectious Diseases found.

"The effect...

Flu continues to spread throughout the United States and has reached elevated levels in nearly every state.

"We're still seeing an increase in activity, which is what we've been experiencing over the last few weeks," said Dr. Scott Epperson, an epidemiologist in the influenza division of the U.S. Centers for Disease Control and Prevention (CDC).

So far the CDC estimates th...

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...

It seems like a no brainer: The flu shot protects heart patients from illness and death, so getting one should be the first thing they do every year before the season starts.

But new research shows that a third of these vulnerable patients don't get vaccinated.

"Patients need to be educated about the benefits of the flu vaccination," said study lead author Dr. Gowtham Grand...

When parents can no longer get "personal-belief" exemptions from childhood vaccinations, they may get around it by asking for religious exemptions for their kids, a new study finds.

Researchers found that after Vermont banned personal-belief exemptions, the number of kindergartners with religious exemptions from vaccination suddenly shot up -- from 0.5% to nearly 4%.

People who contract measles aren't out of the woods after their rash fades and their fever subsides.

They're then more vulnerable to other bacterial and viral infections -- even those they've already been vaccinated against or have had before.

That's because measles virus attacks the cells that serve as the immune system's memory, wiping out established resistance to diseas...

About two-thirds of pregnant women in the United States don't get vaccinated against both flu and whooping cough, putting them and their newborns at risk, a new report from the U.S. Centers for Disease Control and Prevention says.

"Influenza and pertussis (or whooping cough) are serious infections that can be deadly for babies, especially those who are too young to be vaccinated direc...

A tuberculosis vaccine commonly used in other parts of the world might reduce a person's risk of developing lung cancer if given early in childhood, a six-decade-long study reports.

The Bacille Calmette-Guerin (BCG) vaccine is the only vaccine approved for preventing tuberculosis (TB) -- a potentially fatal infectious disease that typically attacks the lungs. Because TB risk is low i...

An experimental vaccine against genital herpes is extremely effective in mice, offering hope of human protection against an incurable sexually transmitted disease.

The vaccine prevented transmission of the herpes simplex 2 virus to nearly all mice that received the shot, said lead researcher Dr. Harvey Friedman, a professor and immunologist at the University of Pennsylvania's Perelman...

Children whose parents take paid family leave when they're born are more likely to get vaccinated at the recommended ages, a new study finds.

"Often this might be...

More than 8 in 10 U.S. adults say kids should be required to get vaccinated in order to attend school, but far fewer trust the safety of vaccines, a new poll finds.

The nationwide poll from the Harvard T.H. Chan School of Public Health sampled 1,550 adults (704 parents and 846 others) and found 84% support rules requiring schoolkids to be vaccinated against diseases such as measle...

The United States could be approaching a state of herd immunity against human papillomavirus (HPV), a virus linked to several cancers.

Oral HPV infections declined by 37% among unvaccinated 18- to 59-year-old men between 2009 and 2016, according to a Sept. 10 report in the Journal of the American Medical Association.

That included a decline in infections of HPV16, the...

There are gaps in immunity against mumps among college-aged Americans who were vaccinated in childhood, researchers say.

Forty percent of U.S. parents say they would likely find a new doctor if their child's primary care provider sees families who refuse childhood vaccines, a nationwide poll finds.

And three in 10 say their child's primary care provider should not treat youngsters whose parents refuse all vaccines.

Those are key findings of the latest C.S. Mott Chil...

Preemies often lag behind full-term babies in getting routine vaccinations -- and the difference remains at age 3, a new study finds.

Misguided parental "hesitancy" over the safety of vaccines for preemies might be to blame, researchers said.

The study found that preterm babies were less likely to be up-to-date on seven recommended vaccines by 19 months of age. More than hal...

Vaccines aren't just for kids, a doctors' group says.

"Many adults are not aware that they need vaccines throughout their lives and so have not received recommended vaccinations," Dr. Robert McLean, president of the American College of Physicians, said in a college news release.

"Adults should get a seasonal flu shot and internists should use that opportunity to make sure th...

California's crackdown on childhood vaccination exemptions cut in half the percentage of kindergartners who didn't have their required immunizations, a new study shows.

The rate of kindergartners without up-to-date vaccinations decreased from around 10% in 2013 to about 5% in 2017, after California implemented a three-pronged strategy to improve immunization rates.

In the midst of the "anti-vaxxer" movement comes more scientific proof that vaccines help save children's lives.

Researchers report that since the 2006 introduction of a vaccine against rotavirus -- a common and potentially fatal cause of infant diarrhea -- U.S. cases have fallen dramatically.

What's more, the rotavirus "season" is now much shorter, shrinking from 26 weeks each ...

The waning effectiveness of a flawed whooping cough vaccine is the main culprit in recent outbreaks of the highly contagious bacterial infection, a new study reports.

More than four out of five confirmed whooping cough (pertussis) cases strike children who are fully vaccinated, the study authors said.

That's because the vaccine for whooping cough loses effectiveness over tim...

The virus that gave you chickenpox as a kid can rise again after decades of inactivity and inflict a painful, even blinding, eye infection in old age.

New research reveals that cases of eye-based "shingles" have tripled since 2004.

In very preliminary findings, an existing rheumatoid arthritis drug appeared to cure one woman of a rare but potentially life-threatening condition known as sarcoidosis.

After 10 months of use, tofacitinib (Xeljanz) appeared to eliminate all symptoms for the woman, who'd tried numerous standard treatments to no avail.

Sarcoidosis is an inflammatory disease that affects mul...

Does getting a flu shot every year diminish its power to protect children?

Absolutely not, say researchers, who found that last year's shot will not in any way reduce the flu-fighting strength of this year's shot.

The conclusion follows three years spent monitoring flu vaccine effectiveness among nearly 3,400 children aged 2 to 17. The researchers said the findings strongly ...

Fear of doctors is common among American preschoolers, and a trip to the pediatrician's office can cause equal anxiety for Mom and Dad.

Half of 2- to 5-year-olds are afraid of going to the doctor, according to a new survey of 726 parents. And some kids get so upset that 1 in 5 parents say they find it hard to concentrate on what the doctor or nurse is saying. Some also say they had po...
