Antibiotics are wrongly being prescribed for infections where they won't work and cutting this down could help combat resistance. But change isn't as easy as just providing the means.
Flu virus mutates so quickly that one year's vaccine won't work on the next year's common strains. But a new way to create vaccines, called 'rational design,' might pave the way for more lasting solutions.
In us, on us and all around us.
