Vaccinated persons* with an exposure to someone with suspected or confirmed COVID-19 are not required to quarantine if they meet all of the following criteria:
Are fully vaccinated (i.e., > 2 weeks following receipt of the second dose in a 2- dose series, or > 2 weeks following receipt of one dose of a single-dose vaccine)
Are within 3 months following receipt of the last dose in the series
Have remained asymptomatic since the current COVID-19 exposure
*Vaccinated inpatients and residents in healthcare settings should continue to quarantine following an exposure to someone with suspected or confirmed COVID-19; outpatients should be cared for using appropriate Transmission-Based Precautions. This exception is due to the unknown vaccine effectiveness in this population, the higher risk of severe disease and death, and challenges with social distancing in healthcare settings*
