SARS-CoV-2 Transmission in a Correctional Facility After Introduction of Vaccination Program — Arizona, December 2020–March 2021
A study conducted by the Centers for Disease Control and Prevention (CDC) in Arizona, United States, found that the introduction of a vaccination program did not completely prevent the spread of COVID-19 in a correctional facility. The study analyzed data from December 2020 to March 2021, a period when the COVID-19 vaccine had been introduced in the facility. The study found that the incidence of COVID-19 was higher among unvaccinated inmates and staff, but vaccinated individuals also contracted the virus. The study concluded that a combination of vaccination, testing, and infection prevention measures is needed to control COVID-19 in correctional facilities. The findings are significant as the study highlights the need for continued vigilance even in settings where vaccination rates are high.
