How many people in the U.S. will have received one or more doses of a COVID-19 vaccine as of 31 March 2021, according to the CDC?

The outcome will be determined using COVID-19 vaccination data as reported by the CDC (updated daily) for “People Receiving 1 or More Doses” (CDC). The data will be accessed no sooner than 4 April 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.
