Claim: Did RFK Jr. secretly block bird flu vaccine development at the FDA, leaving Americans more vulnerable to the next H5N1 pandemic?

The claim that RFK Jr. secretly blocked bird flu vaccine development is mostly false. Some sources suggest that RFK Jr. withdrew funding for a vaccine project, which could impact development. However, there is no clear evidence that this action directly leaves Americans more vulnerable to a pandemic. Mainstream outlets report on the funding withdrawal, while alternative sources exaggerate the consequences, linking it to severe outcomes like mass euthanasia of chickens without substantiated evidence. This discrepancy raises questions about the claim's validity. The models diverge sharply — treat this as higher-uncertainty. Perplexity comes in highest (75%), while OpenAI is lowest (30%). Gemini expresses higher confidence than OpenAI on this claim. Opposing sources claim that RFK Jr.'s withdrawal of funding for the bird flu vaccine could lead to significant public health risks, including the potential for increased vulnerability to H5N1. They argue that the funding was crucial for vaccine development and that its absence could have dire consequences. However, the evidence does not conclusively support that this withdrawal directly endangers public health or that it was a deliberate act to block vaccine development. The lack of direct causation between the funding withdrawal and increased vulnerability to a pandemic diminishes the strength of the claim.
