Vaccines Are Pushing Pathogens to Evolve

Just as antibiotics have bred resistance in bacteria, vaccines can potentially lose their effectiveness over diseases they controlled. Researchers are working to head off the evolution of new threats.

A New Way to Predict Infection’s Toll

Scientists have developed new ways to forecast who will bounce back from disease by studying not just the way the immune system fights infections, but how the body repairs itself.
