Ensuring COVID-19 vaccines work
Before the U.S. Food and Drug Administration determines whether to approve a vaccine or authorize a vaccine for emergency use, clinical trials are conducted to determine how well it works. This is known as effectiveness.
After FDA approves a vaccine or authorizes a vaccine for emergency use, it continues to be studied to determine how well it works under real-world conditions. CDC and other federal partners will be assessing COVID-19 vaccine effectiveness under real-world conditions.

Operation Warp Speed, has been working since the pandemic started to make one or more COVID-19 vaccines available as soon as possible. Although CDC does not have a role in developing COVID-19 vaccines, CDC has been working closely with health departments and partners to develop vaccination plans for when a vaccine is available. CDC is working with partners at all levels, including healthcare associations, on flexible COVID-19 vaccination programs that can accommodate different vaccines and scenarios.

How the CDC is making COVID-19 vaccine recommendations
When the Food and Drug Administration authorizes or approves a COVID-19 vaccine, the Advisory Committee on Immunization Practices will quickly hold a public meeting to review all available data about that vaccine. Before making recommendations, ACIP reviews all available clinical trial information, including descriptions of:
- Who is receiving each vaccine (age, race, ethnicity, underlying medical conditions)
- How different groups respond to the vaccine
- Side effects of each vaccine
