Vaccine Education

Before considering vaccine information on the Internet, check that the information comes from a credible source and is updated on a regular basis.

Finding Credible Vaccine Information

The Missoula City-County Health Department is committed to only providing information from legitimate sources such as the CDC. We encourage the public to also look for vaccine information from legitimate sources such as the CDC, FDA, and WHO. We discourage the public from getting health information from blogs, Facebook groups, internet memes and other illegitimate sources.


CDC’s vaccines and immunization web content, which we often use on our own website, is 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.

CDC’s NCIRD is a member of the World Health Organization’s (WHO) Vaccine Safety Net and follows web content and credibility criteria defined by the Global Advisory Committee on Vaccine Safety (GACVS).

CDC’s vaccines safety site is one of WHO’s 20 English language certified web sites.

While it’s a useful tool for researching health-related issues, the Internet does not replace a discussion with a healthcare professional.
