Who Has CDC Prioritized for Vaccination?

In response to the COVID‑19 pandemic, the Advisory Committee on Immunization Practices (ACIP) has made recommendations on vaccine prioritization. While the supply is limited, vaccination will be available to a limited number of people. Criteria for vaccination and designated vaccination sites may expand as vaccine supply increases. States are making the ultimate determination about who will receive the vaccine first.
