Leveraging seasonal influenza health worker vaccination programmes for COVID-19 vaccine Introduction: A global qualitative analysis

Background

Health worker vaccination programmes can help to safeguard both health workers (HWs) and their patients and enhance vaccine uptake more broadly in local communities and society. This study’s objective was to increase global understanding of how existing HW vaccination programmes were leveraged for emergency COVID-19 vaccine introduction.

Methods

This qualitative study included 13 in-depth group interviews with 38 key informants with expertise in vaccine programme implementation from eleven countries in five WHO regions: Albania, Armenia, Bhutan, Lao PDR, Maldives, Mongolia, Oman, Timor Leste, the United Kingdom, Vietnam, and Zimbabwe in addition to WHO regional focal points from all six regions. These interviews were transcribed, coded, and thematically analyzed. Key informants reviewed the initial results and validated the key findings.

Results

Informants characterized key components of both routine and seasonal influenza vaccination programmes that were leveraged for the emergency vaccination of HWs during the COVID-19 pandemic. We identified a set of cross-cutting factors that were used for COVID-19 vaccine roll out: 1) pre-existing occupational health policies, 2) adequate human resources, 3) well-functioning data information systems and vaccine delivery platforms, and 4) established communication channels. Across the eleven countries and six regions interviewed, the ability to adapt existing influenza or other health worker vaccination infrastructure was beneficial for their pandemic response.

Conclusions

Our findings suggest a strong justification for enhanced investment in vaccination of health workers, particularly against seasonal influenza, through country-wide programmes as a foundation for pandemic preparedness and response.
