Various regional health authorities are implementing or promoting school-based vaccination strategies to increase immunization coverage among students.

In La Rioja, Argentina, the government has relaunched the ‘Activá tu Escudo’ initiative, a joint effort between the Ministries of Health and Education. This program targets approximately 7,000 students across 253 educational establishments to strengthen the National Vaccination Calendar. This follows a pilot phase that reportedly increased coverage by roughly 10%.

In Los Ríos, Chile, health officials are emphasizing the importance of the annual School Vaccination strategy under the National Immunization Program. The initiative aims to provide equitable access to vaccines in both public and private schools, specifically targeting students for the dTpa vaccine to prevent diphtheria, tetanus, and pertussis, as well as the HPV vaccine and measles catch-up doses.
