Ethical Principles

ACIP identified four ethical principles to guide their decision-making process when supply was limited:

  1. Maximize benefits and minimize harms — Respect and care for people using the best available data to promote public health and minimize death and severe illness.
  2. Mitigate health inequities — Reduce health disparities in the burden of COVID-19 disease and death, and make sure everyone has the opportunity to be as healthy as possible.
  3. Promote justice — Treat affected groups, populations, and communities fairly. Remove unfair, unjust, and avoidable barriers to COVID-19 vaccination.
  4. Promote transparency — Make a decision that is clear, understandable, and open for review. Allow and seek public participation in the creation and review of the decision processes.
