  1. What information is available on the NIP website?


  1. Is the NIP website information credible?

Yes, the NIP website information is credible. The NIP website is produced by the National Immunization Program (NIP), the Federal Government's principal agency for immunization research and a component of the Centers for Disease Control and Prevention (CDC). 

And, how do I know if the vaccine information I find on the Internet is accurate?

First, consider the source of information. A good health website will display who is responsible for the content of the site. Also look for a way to contact the information provider or Webmaster. Health information should be accurate and unbiased, and information should not be slanted in favor of a website's sponsor or source of funding. The Evaluating Information on the Web page provides additional information and suggests questions to ask to determine the accuracy of website information.

The NIP website information is reviewed regularly for currency and is updated at least weekly to include the latest facts. Each home page spotlights recently published items at the top of the page. Be sure to visit the site often to get the latest immunization information.


  1. How can I continue to get up-to-date immunization information?
Return to the the NIP website site frequently, because the content changes often to mirror the changes and advances in immunization research. Be sure to check the Spotlight area for the latest topics and the News page for recent immunization articles, and sign up for free newsletters on the NIP website.
