Misinformation and Disinformation

Misinformation is information that is false, inaccurate, or misleading according to the best available evidence at the time. Disinformation is when misinformation is used to serve a malicious purpose, such as to trick people into believe something for financial gain or political advantage.

How To Determine If Information Is Accurate

False or misleading information can cause people to make decisions that could have dangerous consequences for their health. Misinformation about diseases, illnesses, potential treatments and cures, vaccines, diets, and cosmetic procedures is especially harmful.

Consider the following steps to determine if information is accurate:

  • Check the Centers for Disease Control and Prevention (CDC) website, or other public health department websites, to see whether there is information about the claim being made.
  • Ask a credible source, such as a doctor or nurse, if they have additional information.
  • Type the claim into a search engine to see if it has been verified by a credible source.
  • Look at the “About Us” page on the website to see if you can trust the source.
  • If you are not sure about the content, do not share it.

Finding Credible Vaccine Information

The CDC’s vaccines and immunization web content are researched, written and approved by subject matter experts, including physicians, researchers, epidemiologists, and analysts. Content is based on peer-reviewed science. CDC leadership makes the final decision on the words, images, and links to best serve the information needs of the public as well as healthcare providers, public health professionals, partners, educators, and researchers. Science and public health data are frequently updated. Most pages are reviewed yearly.
