The world’s last line of defense against disease-causing bacteria just got a new warrior: vancomycin 3.0. Its predecessor—vancomycin 1.0—has been used since 1958 to combat dangerous infections like methicillin-resistant Staphylococcus aureus. But as the rise of resistant bacteria has blunted its effectiveness, scientists have engineered more potent versions of the drug—vancomycin 2.0. Now, version 3.0 has a unique three-pronged approach to killing bacteria that could give doctors a powerful new weapon against drug-resistant bacteria and help researchers engineer more durable antibiotics.
