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.
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.
COVID-19 is likely to be around for years to come, haunting humans as either a yearly flu-like illness or as a virus that occasionally resurfaces following years of dormancy, a new Harvard modeling study argues.
It's unlikely that COVID-19 will go the way of its closest cousin, SARS (severe acute respiratory syndrome), which was eradicated by an intense public health effort following ...
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."
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...
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 ...
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 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.
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).
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.
"Currently, many people do not vaccinate their child within the recommended schedule and are late," said study co-author Solomon Polachek, a professor of economics at the State University of New York at Binghamton.
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...
Texas cities are in danger of major measles outbreaks because an alarming number of school kids are unvaccinated, researchers warn.
Vaccination rates in the state have declined since 2003 and a computer simulation by University of Pittsburgh researchers found that an additional 5% decrease could increase the size of a measles outbreak by as much as 4,000% in some cities.
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...
The anti-vaccination movement is now a global crisis, an international panel of scientists say, and everyone must do more to combat it.
"We are alarmed that the WHO [World Health Organization] this year declared vaccine hesitancy a top-10 international public health problem. This is a man-made, dangerous and wholly unnecessary crisis," said Dr. Scott Ratzan. He's founding editor of t...
It's not too late to get your flu shot, which can protect you in ways that may surprise you.
The flu vaccine can be a lifesaver for people with heart disease, according to infectious disease specialist Dr. Michael Chang, assistant professor of pediatrics at University of Texas Health Science Center at Houston.
"Previous studies have shown influenza vaccination could reduce d...
