WHO Pre-Qualified (PQ) Vaccine Priority List for 2024-2026

WHO Pre-Qualified (PQ) Vaccine Priority List for 2024-2026



WHO Pre-Qualified (PQ) Vaccine Priority List for 2024-2026

The “Pre-Qualified Vaccine Priority List” has been established through negotiations between the World Health Organization (WHO), the United Nations Children’s Fund (UNICEF), and the Pan American Health Organization revolving fund. It outlines the WHO PQ priority levels for various vaccines.

The WHO updates the list every two years, categorizing vaccines expected to be available within the two-year period into high, medium, low, and no priority levels.

The prioritization of vaccines guides the WHO in concentrating limited pre-qualification resources on priority vaccines, supporting national immunization programs in achieving their goals.

The previous version of the priority list covered the period from 2018 to 2022. In November 2023, the WHO updated the Pre-Qualified Vaccine Priority List for 2024-2026. This is shared with Chinese vaccine companies, allowing them to apply for PQ for high and medium priority vaccines.
