COVID-19 measures have necessarily disrupted vaccinations and have been detrimental to measles prevention. As of October 2021, nearly 41 countries had paused their measles campaigns, leaving more than 94 million people at risk of missing vaccines. Therefore, it is critical for public health officials to continue to provide resources, promote vaccination, and change behaviors despite the pandemic. The study’s purpose is to enhance the information-environment level, population-level, and system-level outcomes to determine infectious disease outbreak and measles outbreak communications effectiveness among parents. Methods: A 2020 web survey using a panel of 460 U.S. adults with children 10 years old or younger. Results: Infectious disease outbreak efficacy was the best individual predictor (? = 0.34, p < .001) of individuals’ information vetting intentions. Information vetting was the best predictor of information seeking intentions (? = 0.38, p < .001) and infectious disease outbreak history salience was the best predictor of information sharing intentions (? = 0.48, p < .001). Discussion: This Risk Communications Evaluation Framework extension demonstrates the applicability in understanding and predicting parents’ infectious disease outbreak information responses, mapping contributing factors, information-environment level outcomes, population-level outcomes, and system-level outcomes to determine risk communications effectiveness. The two new population-level outcomes demonstrate the importance of understanding infectious disease outbreak communications’ dynamics and complexities. Moreover, this study offers public health professionals insight into parents’ infectious disease outbreak information processing and response mechanisms, whom, with varied infectious disease outbreak history salience and involvement level, are confronted by multiple infectious disease outbreak challenges.
