Based on the expected vaccine allocations for Iowa, Phase 1B will focus on individuals who are age 75 and over, as well as other high risk populations. This includes Iowans who are most vulnerable to exposure to COVID-19 or high-risk for illness as the result of a COVID-19 infection, with a significant focus on equity. Vaccination of Phase 1B populations will begin no later than the first of February, and will take several weeks to complete.
