HHS Develops AI Tool to Analyze Vaccine Injury Claims, Raising Misinformation Concerns

Thumbnail Image

The information displayed in the AIM should not be reported as representing the official views of the OECD or of its member countries.

The US Department of Health and Human Services is developing a generative AI tool to analyze vaccine injury data and generate hypotheses about vaccine side effects. Experts warn that, if misused, the tool could fuel misinformation and undermine public health, especially given the agency's current leadership's anti-vaccine stance. The tool is not yet deployed.[AI generated]

Why's our monitor labelling this an incident or hazard?

An AI system is explicitly involved as a generative AI tool analyzing vaccine injury data. The event concerns the development and intended use of this AI system, which could plausibly lead to harm if its outputs are misused to spread misinformation about vaccine safety, potentially undermining public health and causing harm to communities. Since the tool is not yet deployed and no harm has materialized, this constitutes a plausible future risk rather than an actual incident. Therefore, this event qualifies as an AI Hazard rather than an AI Incident or Complementary Information.[AI generated]

Why's our monitor labelling this an incident or hazard?
An AI system (a generative AI tool using large language models) is explicitly mentioned as being developed to analyze vaccine injury data. The system is not yet deployed, so no direct or indirect harm has occurred. The article highlights plausible future harms, such as misuse of AI-generated hypotheses to promote misinformation or undermine vaccine safety, which could lead to violations of public health and harm to communities. Therefore, the event fits the definition of an AI Hazard because the AI system's use could plausibly lead to harm, but no harm has yet been realized.

Why's our monitor labelling this an incident or hazard?
The AI system is explicitly mentioned as being developed to analyze vaccine injury data and generate hypotheses. However, it has not been deployed, and no direct or indirect harm has occurred yet. The concerns about misuse and false alerts represent plausible future harms, making this an AI Hazard rather than an AI Incident. The article does not focus on responses or updates to past incidents, so it is not Complementary Information. It is clearly related to AI and potential harms, so it is not Unrelated.
