‘Leaky vaccines’ don’t affect the ability of the virus to reproduce and spread to others; they simply prevent it from causing disease.

Media coverage of a recent study involving a "leaky" vaccine raised questions about the possibility that they could make viruses more dangerous.

Was the Ebola vaccine 100% effective, or 100% lucky? The good money is on a percentage somewhere in between, but in truth, we will never know.
Hepatitis B is commonly transmitted between children, who are not aware that they are carrying the virus.
Hepatitis B vaccines have been available for over 20 years but the virus is still endemic in Africa, with the continent carrying over one third of the globe's case load.

The anti-vaccination movement is not the cause of falling vaccination rates. It is a symptom of the public’s growing distrust in the government and the medical profession.
Children in particular experience a multitude of viral illnesses during their early years.
Viruses cause all kinds of infections from relatively mild cases of the flu to deadly outbreaks of Ebola. Clearly, not all viruses are equal and one of these differences is when you can infect others.
Vaccines have always had potential side effects but they remain our best defence against far more dangerous infectious diseases.

When the measles vaccine was introduced, it was associated with reductions in more childhood disease deaths than were actually caused by the measles. How does that work?

During World War II the US military forged partnerships with industry and academia that translated laboratory findings into working products at an unprecedented pace.
Exposing people to weak forms of anti-science arguments can help them respond when they are hit by the real thing.
A small dose of a weak form of anti-science can inoculate people against the real thing, just like a vaccine.

Understanding public opinion can help officials target messages during a health crisis. But current survey methods aren't good at generating representative samples. Can Twitter fill in the gaps?
For certain members of the community, catching flu can lead to severe illness or death.
It’s that time of year again when scientists and doctors make predictions about the impending flu season and we must decide whether to go out and get the flu vaccine.
Studies have shown that mentioning misinformation – even in the process of combating it – can cause it to stick in listeners’ minds.
Studies show that the more familiar we become with false information, the more likely we are to later remember it as fact.
New innovations and technologies, such as the Nanopatch developed by Australian biotech Vaxxas, are instrumental to Australia’s future prosperity, and many benefit from NCRIS facilities, which are now under threat from government cuts.
The government believes innovation will be crucial to our future productivity, yet it is threatening cuts to research infrastructure that is instrumental to promoting innovation and new technologies.
Helping parents decide to immunize their children may be a matter of communication.
Research shows that what’s most effective is when health-care providers tailor the conversation to address parents’ particular concerns.

Prior to the 1970s, almost all Phase I and II drug trials were conducted on prisoners. Our standards have gotten better since then, but still need revision.

Kids are flu super spreaders, which is why locating vaccination programs in schools can protect whole communities.
Health marketing materials used to promote measles vaccine during the 1960s.
Before the vaccine, we thought measles was a 'mild' illness. This is because vaccines drive down the number of people getting the disease while increasing our awareness of the risks.
The bacteria living in your gut have more to do with your immune system than you might think.
Your intestines are home to many different kinds of bacteria (and some non-bacterial organisms as well). Together they’re called the “gut microbiome.” They come from the food you eat – and whatever else…
Do more non-medical vaccine exemptions mean a higher incidence of disease?
As of January 30, 102 people in 14 states were reported to have measles, and most of these cases are tied to the outbreak that began at Disneyland in December. Public health officials are citing an increase…
