[Articles] Estimating measles susceptibility and transmission patterns in Italy: an epidemiological assessment

Unvaccinated adults contribute substantially to measles transmission in Italy. Heterogeneous immunity gaps exist across regions, with some regions showing persistently low vaccine uptake in children and other regions showing a high proportion of susceptible adults. These results emphasise the need for tailored vaccination strategies, including catch-up campaigns for adults. By integrating routine surveillance data with modelling techniques, this study presents a resource-efficient approach to quantifying immunity and transmission risks, providing a scalable framework for countries aiming to refine their immunisation policies.
