Mr Aidan O’Leary has been officially appointed as the new Director for Polio Eradication at the World Health Organization, with effect from 1 January 2021.  O’Leary is taking over from Michel Zaffran, who will enter retirement end-February.

O’Leary brings with him a wealth of emergencies and public health experience.  Originally from Ireland, he is currently Head of Office in Yemen for the United Nations Office for the Coordination of Humanitarian Affairs (OCHA), in addition to having extensive experience in emergency settings such as Iraq and Syria, where he also served as Head of Office for OCHA.

O’Leary also has strong experience of working on polio eradication in the remaining wild poliovirus endemic countries.  He was Chief of Polio Eradication in Pakistan for UNICEF from 2015-2017 and Head of Office for OCHA in Afghanistan from 2011-2014.

“I’m excited to join this incredible programme,” commented O’Leary on his appointment. “COVID-19 led to a tough year for polio eradication in 2020, but we have adapted our strategies and I believe this programme has a real opportunity to reboost our efforts in 2021. I’ve been so impressed by how this programme has taken on challenges and continues to innovate, and all of it rooted in its strong partnership. I look forward to working with all partners, including my old organization UNICEF, and of course Rotarians from around the world.”

“With this appointment, I am able to enter my retirement with a sense of reassurance,” said Michel Zaffran.  “He is the right person for the job at this time, given his set of experiences both in the polio programme and emergencies, and in particular in Pakistan and Afghanistan.  I am confident his leadership will help drive this programme to ultimate success.”

O’Leary joins the GPEI in 2021, and will focus on capitalizing on new commitments displayed at the World Health Assembly in November, the introduction of new tools and innovations such as novel oral polio vaccine type 2 (nOPV2), and an optimization of new governance and strategy structures currently being developed across the partnership.

The GPEI welcomes Aidan O’Leary to the GPEI family.
