Vaccines and vaccination against yellow fever

This updated position paper on yellow fever (YF) vaccines and vaccination replaces the previous 2003 WHO position paper and summarizes recent developments in the field. Recommendations on the use of YF vaccines were last discussed by SAGE at its meeting in April 2013.
