Following presentation of the film, the majority of students left the exercise with correct information about vaccines, based on their lessons-learned statement. In this case, 29 of the 31 participants (94%) reported accurate information about vaccines. Of the 49 verifiable facts about vaccines that were reported by participants, only 2 (4%) were incorrect. Students had higher correct scores in the “strength of evidence” exercise following exposure to the video as well. Conclusions: Allowing students to use the Internet to gain information about medical topics should be approached with care since students may take away predominantly incorrect information. It is important to follow up conflicting information with a solid, unambiguous message that communicates those lessons that the instructor deems most important. This final message should be fact based but may need to contain an anecdotal component to counter the strong emotional message that is often delivered by inaccurate Internet sites. %M 18653441 %R 10.2196/jmir.986 %U //www.mybigtv.com/2008/2/e17/ %U https://doi.org/10.2196/jmir.986 %U http://www.ncbi.nlm.nih.gov/pubmed/18653441
