The Advisory Committee on Immunization Practices (ACIP) is a committee within the Centers for Disease Control and Prevention (CDC) that provides advice and guidance on effective control of vaccine-preventable diseases in the civilian population of the United States.
On December 16, 2021, ACIP issued recommendations based on "a clinical preference for individuals to receive an mRNA COVID-19 vaccine over Johnson & Johnson’s COVID-19 vaccine."[1]
