Naloxone is often used to revive people overdosing from opioids.
Scientists are just starting to understand how your parents' genes and experiences might shape your own susceptibility to dangerous drugs. Could that help to stop addictions before they start?
Manufacturing one of the world's most important vaccines will have several benefits for South Africa.

Flu virus mutates so quickly that one year's vaccine won't work on the next year's common strains. But rational design – a new way to create vaccines – might pave the way for more lasting solutions.

The flu is not only making millions of people sick this year. It's causing fear and, along with it, a lot of confusion. Should you get a flu shot? Should you see the doctor? An expert advises.
An annual vaccine is your best protection against the flu.
After Australia's tough flu season, some experts predict that the U.S. is in for a few difficult months. What does that mean for you?
Current plans to eradicate polio mean keeping the virus alive – and risk restarting the epidemic.

Vaccination is not to be taken for granted.
Vaccines are one of the greatest public health achievements in history.
The kinds of vaccines adults need depend on several factors, including whether you were born here, how old you are and whether you intend to travel overseas.
A recent study of medical students and residents found they were reluctant to engage with parents who have vaccination fears. But listening to parents is important.
A recent study suggests that shunning parents who are reluctant to vaccinate their kids isn't the best strategy. A better strategy might be old-fashioned, but it works.
Parents are concerned combination vaccines, which protect against several diseases at once, can be too much for a young immune system to cope with.
Vaccines against multiple diseases in one jab strengthen kids' immune systems, not weaken them. Here's why we shouldn't fear these combination vaccines.
People reject science such as that about climate change and vaccines, but readily believe scientists about solar eclipses, like this one reflected on the sunglasses of a man dangerously watching in Nicosia, Cyprus, in a 2015 file photo.

People universally believe scientists' solar eclipse calendars, but vaccine warnings or climate predictions are forms of science that strangely do not enjoy equivalent acceptance.
In the past year, 3,300 cases of measles were reported in Europe. Most of them were entirely preventable.

Some people have objected to childhood vaccination since it was introduced in the late 1700s. And their reasons sound remarkably familiar to those of anti-vaxxers today.
Computers may play an important role in preparing us for the next viral outbreak – whether flu or Ebola.

This antivirus software protects health, not computers. Researchers are beginning to combat deadly infections using computer-generated antiviral proteins – a valuable tool to fight a future pandemic.
In Australia we still vaccinate against polio, but not tuberculosis. Why, and how do we decide?
Vaccinating against an infectious disease can stop once the threat of future transmission is deemed sufficiently low.
When a man was diagnosed with Ebola in Dallas in 2014, workers cleared out the apartment unit where he had been staying.
President Trump wants to slash global health funding at a time when more investment is needed, not less. This spending can protect Americans – as well as foreigners – from deadly diseases.
To tackle diseases like meningitis, African governments must find fresh ways to fight for lower cost vaccines.
European countries are among the most sceptical of vaccinations – so how do they stay on top of the problem?
