Overview

  • More than 670,000 doses from the first federal shipment were delivered to states this week, activating vaccination through SUS for women from the 28th week of pregnancy.
  • Local campaigns began in multiple capitals and cities, including Belo Horizonte on Dec. 5 and Salvador the same day, with Fortaleza set to offer doses citywide from Dec. 8.
  • Goiás received 24,530 doses, Piauí 11,170, and Fortaleza reported 7,000 doses of Pfizer’s Abrysvo, while Acre started statewide administration across 242 vaccination rooms.
  • The single‑dose regimen is given once per pregnancy and is intended to protect newborns during early life, with clinical data indicating about 81.8% efficacy against severe infant disease in the first 90 days.
  • Health officials cite RSV’s impact—around 75% of bronchiolitis and 40% of pneumonia cases in children under two, with roughly 43,000 severe respiratory cases logged nationally in 2025—and the ministry targets roughly 80% coverage, with purchases planned through 2027.
