For 34 years, Immunize​.org has been trusted as a source of clinical immunization guidance. Today, healthcare professionals (HCPs) and those they serve need sources they can rely on. We remain committed to providing access to evidence-based guidance grounded in credible science and clinical expertise. At this time of year, we come to you to ask for your support with a tax-deductible donation to Immunize.org.

Our role has never been more vital. When questions arise about vaccine recommendations, frontline vaccinators turn to us for clarity. As always, we provide official CDC recommendations; we also provide context and the recommendations of other trustworthy medical sources, such as the American Academy of Pediatrics, ensuring HCPs in any vaccination setting anywhere have ready access to what they need to guide their patients.

Earlier this year, we acted quickly when the LetsGetRealAboutVaccines.org website—developed in 2024 by HHS to provide clear childhood vaccination information—needed a new home. We stepped up to bring it under the Immunize​.org umbrella where its valuable content remains accessible to families and HCPs.

In the past year, your support enabled us to:

• Serve 46,100 daily visitors to Immunize​.org (for HCPs) in September 2025—a 44% increase since September 2024
• Serve 5,100 daily visitors to VaccineInformation.org (for the public) in September 2025—a 180% increase since September 2024
• Deliver downloads of 4.85 million clinical resources and 3.5 million VIS translations in fiscal year 2025
• Inform more than 50,000 HCPs weekly through IZ Express
• Expand our audience on social media by 20% across all platforms
• Maintain current, verified information about all state immunization school and childcare requirements
• Support the National Network of Immunization Coalitions connecting advocates nationwide
• And more

Together, we ensure evidence-based guidance remains available, and we work to make vaccines understandable, affordable, and accessible to all who choose to protect themselves and their families. Please visit our website to donate now. 

With sincere appreciation for your partnership,
