This study examined whether the type of health information source used by parents (verified vs. unverified) was associated with their child's vaccination outcomes. A national sample of 887 parents (55.1% male; mean age = 36.42 years, standard deviation = 12.29) completed an anonymous online survey. Participants reported demographic characteristics, primary health information sources, and whether their child received 12 vaccine recommendations by the Center of Disease Control and Prevention (CDC). Health information sources were categorized as primarily from verified (healthcare providers, scientific journals) or unverified (family\/friends, social media, opinion blogs). Compared to those using unverified sources, verified source users had significantly higher odds of vaccinating their child across most vaccines, including DTaP, Hib, Hepatitis A, Hepatitis B, influenza, MMR, MCV4, pneumonia, IPV, and RV (all <jats:italic>p<\/jats:italic>s &amp;lt; 0.01). Verified source users also reported significantly higher overall vaccination rates (<jats:italic>p<\/jats:italic> &amp;lt; 0.001). These associations remained significant after adjusting for key demographic covariates (e.g., age, household size, number of children). No significant differences were found for the chickenpox or COVID-19 vaccines. Results underscore the importance of health information credibility in promoting vaccine adherence and suggest that targeted efforts to improve access to verified health information may help address childhood vaccination gaps.<\/jats:p>","DOI":"10.3389\/fpubh.2025.1627916","type":"journal-article","created":{"date-parts":[[2025,9,29]],"date-time":"2025-09-29T05:26:27Z","timestamp":1759123587000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Associations between health information source and childhood vaccination"],"prefix":"10.3389","volume":"13","author":[{"given":"Karly S.","family":"Geller","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Skyler J.","family":"Montaine-O'Brien","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul W.","family":"Branscum","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brandy N.","family":"Reeves-Doyle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,9,29]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"682","DOI":"10.15585\/mmwr.mm7331a2","article-title":"Health and economic benefits of routine childhood immunizations in the era of the Vaccines for Children program\u2014United States, 1994\u20132023","volume":"73","author":"Zhou","year":"2024","journal-title":"MMWR Morb Mortal Wkly Rep"},{"key":"B2","unstructured":"Fast facts: Global immunization.
