Early attempts at a vaccine during the 1918 influenza pandemic were based on this understanding, and it was not until the 1930s, when the influenza virus was identified, that progress towards an effective vaccine could really begin.
In 1919, doctors attempted to vaccinate patients against influenza, developing a vaccine for Pfeiffer’s bacillus that proved completely ineffective. After the pandemic had passed, biomedical researchers began to reevaluate the etiology of influenza with the goal of preventing a future pandemic.
Influenza, commonly known as the flu, is an infectious disease caused by influenza viruses. Symptoms range from mild to severe and often include fever, runny nose, sore throat, muscle pain, headache, coughing, and fatigue. These symptoms begin one to four (typically two) days after exposure to the virus and last for about two to eight days.
