Brazilian health authorities are expanding efforts to protect infants from respiratory syncytial virus (RSV) through a new vaccination programme for pregnant individuals. RSV is a common virus, but can be particularly dangerous for babies, frequently enough leading to bronchiolitis and hospitalization. Following the vaccineS inclusion in Brazil’s Unified Health System (SUS) in December, officials are now emphasizing the importance of maternal immunization to provide crucial antibody protection to newborns during thier most vulnerable months – a strategy mirroring successful programs implemented in the United States and Europe earlier this year.
Health officials are urging pregnant individuals to get vaccinated against respiratory syncytial virus (RSV) as cases of the virus, a leading cause of bronchiolitis, are expected to rise. This preventative measure is a key strategy to protect newborns, who are particularly vulnerable to severe respiratory complications.

Since the RSV vaccine was added to Brazil’s Unified Health System (SUS) in December, approximately 88,400 pregnant individuals have been immunized nationwide. The vaccine works by transferring antibodies from the mother to the baby during pregnancy, offering crucial protection during the first few months of life when infants are most susceptible to severe bronchiolitis.
The Ministry of Health estimates that vaccinating pregnant individuals could prevent around 28,000 hospitalizations due to bronchiolitis each year, benefiting approximately two million newborns. A total of 1.8 million doses of the RSV vaccine have been purchased for distribution through the public healthcare network.

Bronchiolitis is a common respiratory infection in young children, particularly those under two years old. While many cases are mild, the illness can become severe, especially in newborns, premature infants, and children with underlying health conditions. The Ministry of Health recommends that pregnant individuals seek information about vaccination at healthcare facilities starting at the 28th week of gestation and ensure their vaccination schedules are up to date.
