Background: Since the supply of coronavirus disease 2019 (COVID-19) vaccines will be limited worldwide, it is essential to prioritize vaccination based on scientific evidence. Although several frameworks and studies on vaccine distribution have been published, no published systematic review has evaluated the prioritization of the COVID-19 vaccine. Materials and Methods: We searched 4 different databases, PubMed, SCOPUS, Web of Science, and EMBASE for articles published between January 2019 and December 31, 2020. Studies were included if they contained the primary search terms “vaccine”, “COVID-19”, and “prioritization”. In addition, we manually included reports from national and international websites. Results: Thirteen studies met the inclusion criteria. In these studies, older adults were the most frequently mentioned group, and healthcare workers (HCWs) were mentioned as the 1st priority group. HCWs and patients with comorbidities were the 2nd and 3rd most frequently mentioned groups in the reviewed papers. Reducing severe COVID-19 was the most frequently mentioned goal. Conclusion: Since vaccination programs have been initiated in several countries, scientific evidence on vaccination prioritization is needed to increase our knowledge of general vaccine prioritization and improve vaccine acceptance. Our results showed that HCWs and older adults were the most frequently valued in studies.
