Overview
- The campaign began simultaneously across the country on January 12 for pregnancies between 32 and 36 weeks, is free, requires no medical order, and only needs proof of gestational week.
- The vaccine, authorized by ANMAT for use in pregnancy, is procured and distributed by the national government, while provinces and Buenos Aires City manage delivery through local vaccinatory networks.
- Starting in January is designed to precede the usual March–April rise in RSV circulation, with each jurisdiction setting an end date based on viral surveillance.
- Preliminary 2025 data showed about 65% coverage and a 62% reduction in infant hospitalizations with a 70% drop in ICU admissions among babies under six months.
- Provinces are setting local goals and timelines—Mendoza aims to vaccinate about 11,000 pregnant people through August 31—while Rosario hospitals report fewer severe cases and a smaller share of hospitalizations among infants under six months after last year’s rollout.
