New research from Emory University School of Medicine shows that a chemical in the mucus of South Indian frogs is capable of killing certain strains of the influenza virus. It’ll take a while for scientists to translate this finding into a useful medicine, but the discovery could lead to an entirely new source of…
To prevent the spread of infectious diseases, Prime Minister Malcolm Turnbull of Australia is pushing its states and territories to adopt measures that would prevent unvaccinated children from attending childcare centers. Sounds harsh, but experts say it’s a good idea—one that’ll hopefully prevent the spread of…
Sometimes it looks like one thing causes another. Every time you eat ice cream, your nose hurts. Every time you turn on the sink, your pipes clank. Or in this case, HPV vaccines seem to coincide with strange side effects.
Endemic measles has officially been wiped out in the Americas. That means the only outbreaks that happen are those imported from abroad. It’s the first region in the world to achieve this certification, but the battle against measles is far from over. We’re looking at you, anti-vaxxers.
In an effort to curb the dangerous trend of vaccine avoidance, the Liberal government in Ontario wants parents seeking vaccine exemptions for their kids to attend a mandatory education session. It’s a good idea, but getting anti-vaxxers to change their opinions will probably require more than that.
A decade after its introduction, the vaccine for human papillomavirus has reduced the prevalence of this cancer-causing STD in teenage girls by nearly two-thirds. It’s an incredible success story, leading experts to question why HPV vaccinations aren’t more common in the United States.
A third of the world’s population is at risk of contracting Dengue Fever, a miserable virus that’s a leading cause of illness and death in the tropics. Now, for the first time ever, three countries have approved a promising new vaccine.
The history of inoculation may sound a little dry, but it’s really an epic tale of human trafficking, semi-illicit experimentation, and high explosives. It’s a globe-hopping story that stars harem girls, noblewomen, prisoners, princesses, slaves, and even a witch hunter.
If you’ve been debating whether to get a flu shot, you should watch this beautifully terrifying animation of a virus taking over a cell and sending millions of its progeny off to spread the infection.
Chalk up a major win for global health: according to the World Health Organization, Africa has been free of wild cases of Polio since July. This comes down to a dedicated vaccination campaign that has advanced the continent towards zero cases.
Flu shots may soon be a lot less painful for young children and older adults. Researchers say they’ve found a way to modify the nasal spray version of the vaccine to make it work for those two groups.
A new research letter published in JAMA Pediatrics is the first to positively link low vaccination rates to the Disneyland measles outbreak that emerged in California late last year. The new research also shows how frighteningly fast measles can spread in a population that's insufficiently immunized against the highly…
The recent measles outbreak has everyone taking another look at "childhood" diseases. Why are these diseases, relatively mild in children over five, so often devastating to adults? An infectious disease expert talks to io9 about possible explanations for why these viruses hit us hard when we should be at our…
A recently approved vaccine called Gardasil 9 protects against more strains of HPV and HPV-related cancers than any vaccine currently available. But who should get it? And how did it get so much better? Here's a complete rundown on the state of the art in HPV-cancer prevention.
More than 150 years ago, the British government made smallpox vaccination compulsory, resulting in a massive political backlash. Opponents used tactics and arguments that are familiar today. If anything, the contemporary anti-vaxxer has regressed even further.
Flooding in Pakistan has stranded hundreds of thousands of people, an anti-vaccination movement trending in L.A.'s most affluent neighborhoods is causing a whooping cough epidemic, and one broken air conditioner could destroy Rome's most priceless art. Hope you're comfortable, this week's What's Ruining Our Cities is…
A whooping cough epidemic is sweeping across California—and 94% of the cases involve children and infants, for whom the illness can be fatal. Low vaccination rates are responsible for the outbreak. But, surprisingly, it's the most affluent, educated parents who are opting out of immunization programs.
In 1977, measles was spreading across the U.S. in outbreaks of epidemic proportions. Less than 70% of children had been immunized due, in part, to a public backlash against swine flu vaccinations, which were rumored to be deadly. Fortunately, the CDC got help from two of the nation's top celebrities.
It's not just the myth about autism that's driving down vaccination rates. Many parents believe that as long as most other children are vaccinated, their kids won't get sick. It's a faulty interpretation of "herd immunity" — and it's prompting families to prioritize exaggerated, imagined risks over actual benefits.
Two years ago, students at Carlsbad High School began filming a documentary, The Invisible Threat—a report on the "science of disease and the risks facing a society that is under-vaccinated." But it is only now that the public is able to see the film, which became the target of a national anti-vaxxer campaign.
