In the rapidly evolving landscape of digital health information, artificial intelligence is emerging as a powerful tool in addressing vaccine misinformation and supporting public health communication. Large language models (LLMs) like ChatGPT are increasingly becoming integrated into search engines, offering human-like text responses based on vast data repositories.
ChatGPT, which gained widespread public attention following its free launch in 2022, has demonstrated promising capabilities in providing science-based vaccine information. Recent academic research has assessed these AI tools favorably, with one study finding that scientific experts rated AI-generated vaccine information as 85% accurate—superior to traditional search engines in focus and relevance, though still with room for improvement.
The technology presents intriguing possibilities for personalized health communication. Researchers suggest AI chatbots could potentially tailor responses according to users’ personality traits and existing beliefs—an approach that aligns with psychological research on addressing vaccine hesitancy through targeted messaging.
Early attempts at health-focused AI assistants have shown mixed results. The World Health Organization’s S.A.R.A.H. (Smart AI Resource Assistant for Health) prototype demonstrated potential benefits but faced criticism for avoiding difficult questions about vaccine safety. Despite these shortcomings, such tools highlight the potential for multilingual, accessible scientific information delivered through websites or smartphone applications.
To explore these possibilities further, Vaccines Today conducted an interview with ChatGPT itself. The AI produced extensive, detailed responses to questions about its role in tackling vaccine misinformation, its information sources, and the future of AI in health communication.
ChatGPT identified established health organizations as its information sources, including the World Health Organization, European Centre for Disease Prevention and Control, European Medicines Agency, and the U.S. Centers for Disease Control. It claimed to summarize their guidance in accessible language to enhance public understanding.
When asked about accuracy, the AI stated its answers on stable topics like routine immunization typically exceed 90% accuracy, though it acknowledged the potential for errors, particularly with rapidly changing information or ambiguous questions. It emphasized that users should verify information through official health sources.
The conversation revealed both strengths and limitations. ChatGPT displayed a tendency toward flattery, describing Vaccines Today as “a trusted European platform” with content “written in accessible, conversational language.” It also demonstrated creative initiative, unprompted, by designing an imaginary ECDC Vaccine Companion chatbot, complete with sample dialogues and interface mockups—though no such partnership exists with the European agency.
Among the most significant concerns with AI health communication are “hallucinations”—false statements generated by AI systems. ChatGPT acknowledged these risks, noting they could spread incorrect medical advice, erode public trust, or distort understanding of vaccines. It suggested mitigation strategies including transparency, continuous model evaluation, verification against trusted databases, and clear citation practices.
Looking forward, ChatGPT outlined a vision where LLMs evolve from simple information tools to interactive health companions, featuring personalized dialogues, plain-language scientific summaries, and integration with trusted health systems. It emphasized the importance of human-AI collaboration, with AI handling routine queries while healthcare professionals address complex or emotionally sensitive discussions.
For such systems to succeed, the AI stressed core principles: accuracy, transparency, human oversight, privacy protection, equity across languages and literacy levels, and institutional accountability. The EU, with its strong regulatory framework, could potentially lead in developing a “European Health AI Framework” with certification standards for health-focused AI applications.
The long-term vision presented is one where AI becomes an integral component of health literacy—available around the clock in multiple languages to explain vaccines, clarify risks and benefits, and connect users with human experts when necessary. If governed by transparency, empathy, and scientific rigor, such systems could potentially strengthen informed decision-making and help rebuild public trust in vaccination programs worldwide.
As AI continues to advance, the balance between technological capabilities and responsible implementation will remain crucial in ensuring these tools serve as effective allies in public health communication.

This is an intriguing concept for leveraging AI to address vaccine misinformation. Tailoring responses based on individual beliefs and personality traits could be an effective approach. I’m curious to see how the technology develops and if it can truly make a meaningful impact on public health communication.
This is an important step in the fight against vaccine misinformation. AI’s ability to provide personalized, science-based information could be a valuable tool, but it must be developed and deployed responsibly. Rigorous testing, oversight, and a human-centric approach will be crucial to its success.
This is a fascinating development in the public health landscape. While I’m encouraged by the potential of AI to improve vaccine information access, I share the concerns about accuracy, bias, and the need for human oversight. It will be interesting to see how this technology is refined and deployed in the years ahead.
While I’m generally supportive of using AI to address public health challenges, I have some reservations about its application in vaccine communication. The risk of bias, inaccuracies, and privacy concerns must be carefully managed. A balanced, multi-stakeholder approach is needed to ensure this technology is truly beneficial.
This is a complex issue with both promising and concerning aspects. I’m encouraged by the potential of AI to improve vaccine communication, but the challenges around accuracy, bias, and privacy must be addressed. A collaborative, evidence-based approach that centers human expertise will be critical going forward.
As an educator, I’m excited to see the potential of AI-powered vaccine information. The ability to tailor messaging and combat misinformation could be transformative. However, I share the concerns about the limitations of the technology and the need for human oversight. It will be fascinating to see how this space evolves.
This is an exciting development in the fight against vaccine misinformation. AI’s ability to tailor messaging and provide science-based information could be a game-changer. I’m curious to see the long-term impacts and how the technology evolves to best serve public health needs.
As a parent, I’m intrigued by the idea of AI chatbots tailoring vaccine information to individual beliefs and concerns. Anything that can help combat misinformation and empower people to make informed decisions about their health is worth exploring. However, the technology must be implemented thoughtfully and with transparency.
I have mixed feelings about this. On one hand, AI could be a powerful tool for disseminating accurate vaccine information. But there are valid concerns around privacy, bias, and the limitations of the technology. I think a balanced, human-centric approach is needed as this space continues to evolve.
As someone who works in the healthcare industry, I’m cautiously optimistic about the potential for AI-powered vaccine communication. The ability to personalize messaging and combat misinformation is promising, but the technology must be rigorously tested and implemented with strong safeguards.
I’m skeptical about relying too heavily on AI chatbots for sensitive health information. While they may improve over time, there are still concerns around accuracy, bias, and the ability to address nuanced individual concerns. A human-centered approach with AI as a supportive tool seems prudent.
That’s a fair point. The human element will likely always be crucial, especially for complex medical topics. AI should complement, not replace, direct interactions with healthcare providers and public health experts.
