New CDC Vaccine Messaging Style Linked to Lower Public Trust, Survey Shows

A recent survey suggests that the U.S. Centers for Disease Control and Prevention’s (CDC) new way of talking about vaccines and autism—one that highlights scientific uncertainty—may be backfiring. Researchers found that this approach could be making people more hesitant to get vaccines and more likely to agree with arguments that reject science.

The study looked at how the CDC now presents evidence on the topic of vaccines and autism. Instead of stating clear conclusions, the agency has shifted to a message that emphasizes what scientists do not know for sure. According to the survey results, this uncertainty-based messaging appears to be eroding trust in vaccines. It may also be strengthening support for strategies that deny established scientific facts.

The findings indicate that even well-intentioned efforts to be transparent about scientific limits can have unintended consequences. When public health officials focus on what remains unknown, some people may interpret that as a reason to doubt vaccine safety. The researchers warn that this could fuel vaccine hesitancy and make it harder to maintain high vaccination rates.

The survey did not test actual vaccine behavior, but it measured shifts in attitudes and beliefs. The authors stress that the CDC’s original intent was likely to build trust by being honest about gaps in research. However, the results suggest the opposite effect may be occurring.
