Multiple studies and systematic reviews indicate that public awareness and health communication campaigns can successfully influence public knowledge, risk perception, and health-related behaviors. However, the magnitude of these behavioral changes often depends heavily on strategic message design and integration with community or clinical support.
The retrieved literature consistently supports the claim that public awareness campaigns produce measurable changes in health behaviors and cognitive outcomes, with multiple studies and systematic reviews showing positive effects on antibiotic use, vaccination uptake, risk perception, and disease prevention. No papers refute the claim, so the verdict is SUPPORTED.
