A universal infant vaccination campaign in China has led the Hepatitis B virus (HBV) to more than double its rate of "breakout" mutations. These mutations may enable the virus to elude the vaccine, necessitating new vaccination strategies. Researchers at the Chinese Centers for Disease Control a... Read More
Finding that part of the story of Louis Pasteur's rabies vaccine is false, Héloïse Dufour and Sean Carroll explore how science fables are born, spread and die.
