Yellow fever vaccine: WHO position on the use of fractional doses – June 2017

The current WHO position on the use of yellow fever (YF) vaccine is set out in the 2013 WHO position paper on vaccines and vaccination against YF and those recommendations are unchanged. This addendum to the 2013 position paper pertains specifically to use of fractional dose YF (fYF) vaccination in the context of YF vaccine supply shortages beyond the capacity of the global stockpile. Recommendations on the use of fractional dose YF vaccine were discussed by SAGE in October 2016.
