The FDA approved a vaccine for dengue virus, which causes dengue fever, it said yesterday in a statement. The vaccine, called Dengvaxia, was previously approved in the European Union and 19 other countries.

You don’t need to worry about getting the vaccine before you go on a vacation unless you’ve already had dengue disease in the past. “The first infection with dengue virus typically results in either no symptoms or a mild illness that can be mistaken for the flu or another viral infection. A subsequent infection can lead to severe dengue, including dengue hemorrhagic fever (DHF), a more severe form of the disease that can be fatal,” the statement explains.

If you think you’ve had dengue virus in the past but aren’t sure, a blood test can confirm it for you. So if you frequent tropical locations and you’re pretty sure you had dengue disease as a kid, it might be worth your while to talk to your doctor about getting Dengvaxia. After the initial dose of the vaccine, you need to get a second dose 6 months later, then a third another 6 months after that.  Read full article

The World Health Organization (WHO) and the European Commission joined forces to tackle the issue at the first global vaccination summit. Although many of them live in developing countries with poor access to vaccines, scientists are worried that anti-vaccination campaigners in the developed world are spreading misinformation on social media. So what’s the cure for their scepticism?

Emilie Karafillakis, research fellow for the Vaccine Confidence Project, speaks to France 24 about the rising anti-vaccination sentiment that is rising throughout Europe, especially in France where a recent study revealed 1 in 3 citizens believe vaccines are unsafe.

In this episode of Take as Directed, J. Stephen Morrison speaks with Dr. Heidi Larson on why vaccine confidence is currently in crisis, and how this has fueled outbreaks such as measles and the persistence of polio in Afghanistan and Pakistan.
