Limited COVID-19 vaccine supply necessitates prioritization. This review found healthcare workers and older adults were consistently prioritized in studies aiming to reduce severe disease.
Area of Science:
- Public Health
- Epidemiology
- Vaccinology
Background:
- Limited global supply of coronavirus disease 2019 (COVID-19) vaccines requires evidence-based prioritization strategies.
- Existing frameworks for vaccine distribution exist, but a systematic review on COVID-19 vaccine prioritization was lacking.
Purpose of the Study:
- To systematically review and evaluate existing scientific evidence on the prioritization of COVID-19 vaccination.
- To identify frequently prioritized groups and stated goals in COVID-19 vaccine distribution studies.
Main Methods:
- A systematic literature search was conducted across PubMed, SCOPUS, Web of Science, and EMBASE databases.
- Included studies published between January 2019 and December 2020 using keywords 'vaccine', 'COVID-19', and 'prioritization'.
- National and international reports were manually incorporated.
Main Results:
- Thirteen studies met the inclusion criteria for the review.
- Older adults were the most frequently mentioned group for prioritization.
- Healthcare workers (HCWs) were identified as the primary priority group, followed by patients with comorbidities.
Conclusions:
- Scientific evidence on vaccination prioritization is crucial as global vaccination programs commence.
- Findings highlight the consistent prioritization of HCWs and older adults in COVID-19 vaccine distribution studies.
- This review contributes to understanding general vaccine prioritization and can inform strategies to improve vaccine acceptance.
