Influenza vaccination. Nurse preparing a syringe that contains a dose of a vaccine to be used to vaccinate against influenza. Influenza vaccines contain dead influenza viruses. When injected, these stimulate the body's immune system to produce antibodies that protect against future infection by live viruses. Photographed in February 2013, at the Omsk paediatric polyclinic, Omsk, Russia, during an influenza outbreak.
