Abstract

Objective: To describe the current status of COVID-19 vaccine guidelines.

Study design and setting: We searched databases, Google and guideline platforms to retrieve COVID-19 vaccine guidelines published between January 1, 2020 and July 8, 2021. We worked in pairs to identify the eligible guidelines and extract data of whether the methodology, funding, and conflict of interests were assessed/reported, and so on. Results were presented descriptively.

Results: A total of 106 COVID-19 vaccine guidelines were included. In the first half of 2021, on average 15 guidelines were published every month. Fifty (47.2%) guidelines addressed the vaccination of people with specific medical conditions, and 18 (17.0%) guidelines focused on adverse effects after vaccination. Only 28 (26.4%) guidelines reported the methodology they used. Four (3.8%) of guidelines assessed both the quality of evidence and strength of recommendations; 42 (39.6%) and 65 (61.3%) guidelines reported their funding sources and conflict of interest, respectively. Most guidelines were published in English (n = 92, 86.8%).

Conclusion: A high number of guidelines on COVID-19 vaccines have been published in the recent months, but most of them lack clear and transparent reporting of methodology, funding, and conflicts of interest. Rigorous methodological and reporting quality evaluation of these guidelines is needed.
