Newborn screening programs promote vaccine acceptance among parents in Turkey: a cross-sectional study

This study found lower vaccine hesitancy among participants in newborn screening programs and those whose parents received adult vaccinations, potentially due to increased contact with health professionals and greater health-seeking behavior. The influence of social media on vaccine hesitancy, evident in the general population, was not observed among cases, suggesting that systematic follow-up may buffer against external risk factors. Studies with matched cohorts, real-time data collection, and anonymous surveys are needed to improve generalizability, support causal inference, and reduce biases.
