How many people in the US will have received one or more doses of a COVID-19 vaccine as of 30 June 2021, according to the CDC?

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 on 12 July 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.
