A Surveillance Study on Timing and Coverage Of Rotavirus and MenB Vaccine Co-administration in Campania Region, Italy

A two-phases study will be carried out with the following aims 1. st phase (2018-2020) * To investigate the vaccination coverage for Rotavirus vaccine (RV) in Campania Region together with other pediatric vaccinations scheduled in the first 12 months of life: hexavalent, pneumococcal conjugate (PCV), meningococcal B (MenB) * To collect data on appropriate timing of the 3 doses of human bovine pentavalent reassortant vaccine (RV5) administration * To evaluate the frequency of a co-administration of RV5 with other vaccines scheduled in the first 12 months of life (hexavalent/PCV+RV5, MenB+RV5 vs RV5 alone) and assess the variability in co-administration rates according to RV5 dose 2. nd phase (2020-2022) * To investigate the effect of Coronavirus-Disease-19 (COVID-19) pandemic on vaccination coverage in the first year of life, focusing on RV vaccination * To investigate the effect of COVID-19 pandemic on timing of vaccine administration in the first year of life, focusing on those vaccines without catch-up vaccination schedule (i.e. RV) Hypothesis are the following: * Vaccination coverage and timing of vaccines scheduled in the first year of life are not fully aligned with what is established by the Italian National Prevention Plan 2017-2019 * Co-administration of RV5 and MenB in comparison with other coadministration e.g. hexavalent/PCV is lower * Co-administration of RV5 and MenB allows to ensure appropriate timing of RV vaccination schedule * COVID-19 pandemic may have affected the overall vaccination coverage as well as the timing of selected vaccination scheduled in the first year of life, with a more relevant impact on vaccines for whom a catch-up vaccination schedule is not feasible, such as RV immunization.
