Polio, smallpox, tuberculosis and the flu are just a few of the threats to the health of the city throughout the years. These photos showcase the hospitals, vaccination programmes which all had one common aim - to help keep people alive. The photos are a mix from the YEP archive and others published courtesy of photographic archive Leodis, which is run by Leeds Library & Information Service. They also run heritage blog The Secret Library Leeds, which provides a behind the scenes look at the Central Library and highlights from its special collections, including rare books hidden away in the stacks.
