WHO meeting on composition of influenza vaccines for 2020 southern hemisphere influenza season

23-26 September 2019 Geneva, Switzerland

The WHO advisory group of experts will hold its consultation meeting in Geneva, Switzerland, on 23-26 September 2019 to prepare its recommendations on the composition of the influenza vaccines for use in the 2020 southern hemisphere influenza season.

The consultation meeting will be followed on the morning of 27 September 2019 by an information meeting for representatives and individuals from vaccine regulatory agencies, influenza vaccine manufacturers, members of the WHO Global Influenza Surveillance and Response System (GISRS), and other interested institutions.

Further information on the consultation and registration is available on the WHO website.


Twice annually, WHO organizes consultations with an advisory group of experts to analyse influenza virus surveillance data generated by the GISRS, and issue recommendations on the composition of the influenza vaccines for the following influenza season. These recommendations are used by the national vaccine regulatory agencies and the pharmaceutical companies to develop, produce and license influenza vaccines.
