In plain language
Evidence on vaccine mandates is scattered across many studies of varying design. This paper builds an open repository of COVID-19 vaccine-mandate studies and works through a scoping review of the quasi-experimental evidence, so that others can locate and build on it.
Research question
What quasi-experimental evidence exists on the effects of COVID-19 vaccine mandates, and how can that evidence be made findable and reusable?
Approach
An open, structured repository of studies together with a worked scoping review of quasi-experimental evidence.
Contribution
It turns a dispersed literature into a reusable resource and demonstrates how to review the quasi-experimental evidence transparently. Dr Genie is a co-author.
Why it matters
It supports cumulative, reproducible research on mandate effects and is listed among the public resources on the data and code page.
