Vaccinating humanitarian workers against COVID-19.

Area of Science:

• Global Health Security
• International Relations
• Vaccine Deployment Strategies

Background:

• Limited COVID-19 vaccine access in humanitarian settings posed risks to essential personnel.
• Frontline humanitarian workers require vaccination to maintain critical operations in challenging environments.

Purpose of the Study:

• To outline the United Nations' (UN) COVID-19 vaccination program for frontline humanitarian personnel.
• To detail efforts to vaccinate staff in regions with restricted vaccine availability.

Main Methods:

• A two-tiered operational structure: global vaccine deployment support and local teams.
• Utilized WHO-approved vaccines and established prioritization criteria for equitable distribution.
• Ensured UN personnel vaccines did not divert from intended national populations.

Main Results:

• Established 120 deployment teams across 152 locations, targeting ~673,000 individuals.
• Administered 337,072 vaccine doses by April 2023, with significant allocation to hardship countries.
• Reported 95 severe adverse events, with no fatalities, permanent disabilities, or medical evacuations.

Conclusions:

• The UN vaccination program demonstrated effective global coordination and adaptable local implementation.
• The program's model offers a framework for future global health emergency responses and aid deployment.
