Brazil Launches Maternal RSV Vaccination in December After Buying 1.8 Million Doses

Overview

• The Health Ministry will ship an initial 673,000-dose lot to states by late November, with vaccinations beginning as doses arrive throughout December.
• The vaccine is now in the National Gestational Immunization Schedule as a single dose from the 28th week of pregnancy, with no age limit for the mother and an 80% coverage goal.
• Authorities say the shot can be administered alongside influenza and COVID-19 vaccines during prenatal visits at primary care units.
• Clinical data cited by officials report 81.8% efficacy against severe RSV outcomes in the first 90 days of life, as Brazil logged 43,100 RSV-related severe respiratory cases in 2025 with most hospitalizations in children under two.
• The SUS offer is free, a plan to acquire 4.2 million more doses runs through 2027, and reports differ on the current purchase value—R$1.7 billion per Agência Brasil versus R$1.17 billion per G1.
