Francis had developed a primitive vaccine that showed promise in the lab but it was nowhere near ready for general testing. Influenza vaccines also known as flu shots or flu jabs are vaccines that protect against infection by influenza viruses. He told us The bacterial vaccines developed for Spanish influenza were probably ineffective because at the time it was not known that pneumococcal bacteria come in many many serotypes and that of the bacterial group they called B.

Louis Pasteur had developed rabies vaccine for post-exposure prophylaxis after an encounter with a rabid animal. Its discovered that flu viruses change from year to year and the vaccine will need to be adjusted annually to be effective. In 1933 researchers discovered that viruses influenza virus types A B and rarely C cause influenza flu.

What new technologies. To answer this its important to understand why we dont just use the same flu vaccine each fall. However the healthcare community is slowly but surely pushing for vaccines that are.

In six months scientists had developed a vaccine. Doctors and scientists first developed viable flu vaccines in the 1940s so they were not starting from scratch when they went to work on the 1957 flu vaccine. In 1938 Jonas Salk and Thomas Francis developed the first vaccine against flu viruses.

This is a timeline of the development of prophylactic human vaccinesEarly vaccines may be listed by the first year of development or testing but later entries usually show the year the vaccine finished trials and became available on the market. Influenzae only one type is a major pathogen In other words the vaccine developers had little ability to. While their effectiveness varies from year to year most provide modest to high protection against influenza.

Prior to 1933 people thought a bacterium named Haemophilus influenzae caused the flu.
