The outcome will be determined using COVID-19 vaccination data as reported by the CDC (updated daily) for “People with at least One Dose” (CDC). The data will be accessed no sooner than 9 May 2021. If the CDC changes how it reports vaccination data, we will provide clarifying language as necessary. For the purposes of this question, a person receiving a single-dose vaccine would count as a person having received one or more doses of a COVID-19 vaccine.
