Cumulative vaccinations with 1 or 2 doses of messenger RNA (mRNA) vaccines (top panel) and 14-day rolling rates of confirmed infections per 10 000 person-days by vaccination status (bottom panel), among study cohort of incarcerated people in California state prisons without confirmed infections prior to 22 December 2020. Time periods with <200 people tested were excluded. Shaded areas represent 95% confidence intervals. Partially vaccinated status defined as ≥14 days after a first dose until receipt of a second dose; fully vaccinated status defined as ≥14 days after a second dose.
