Abstract
Considering that RV is the causative agent in 20% of AGE cases, a direct effectiveness of 82% preventing AGE-PC episodes due to RV could be deduced using a novel spatiotemporal approach. A reduction of 17% of AGE-PC episodes in unvaccinated was observed in areas with VC over 70% because of indirect protection. • The effectiveness of RV vaccines preventing hospitalizations due to RV-acute gastroenteritis (RV-AGE) has been extensively studied. However, RV also burdens the primary care (PC) setting, and data on vaccine effectiveness (VE) in preventing AGE-PC visits are scarce. •The RV vaccine distribution in Spain (non-funded), with large differences in vaccine coverage (VC) among healthcare districts, provides an ideal scenario to assess the actual VE in preventing AGE-PC consultations, including the direct and indirect protection. • A direct effectiveness of 82% preventing AGE-PC episodes due to RV could be deduced using a novel spatiotemporal approach. A reduction of 17% of AGE-PC episodes in unvaccinated was observed in areas with high VC because of indirect protection. • These findings, together with existing data on the impact on hospitalizations due to RV-AGE, offer valuable insights for implementing vaccination initiatives in countries that have not yet commenced such programs.
