Protecting Your Newborn from RSV: Essential Facts on Maternal Vaccines and Infant Treatments

Protecting Your Newborn from RSV: Essential Facts on Maternal Vaccines and Infant Treatments

Welcoming a new baby brings immense joy, but it's natural to worry about seasonal illnesses. Respiratory syncytial virus (RSV), a highly contagious respiratory infection, is a major concern for parents during peak virus season. 

At Dr. Sindu Pillai, MD Inc. in Murrieta, California, Dr. Sindu Pillai and our dedicated pediatric team help families safeguard their littlest members. Whether you're planning ahead with prenatal visits or scheduling your baby's first newborn visits, we're here to guide you through the latest protective measures.

Understanding the impact of RSV on infants 

Many people mistake RSV for a common cold, but it's a virus that can quickly progress to a severe lung infection in babies. According to the American Academy of Pediatrics (AAP, 2025), over 62,000 children under age five were admitted to US hospitals with RSV during the 2024-2025 respiratory season.

Because newborns have developing immune systems and small airways, they're at the highest risk for severe complications like bronchiolitis, which is inflammation of the small airways in the lungs. Fortunately, parents now have highly effective tools to build a strong shield of defense before and after birth.

Maternal vaccines: Protection before birth

One of the most effective ways to protect your baby is by getting vaccinated during pregnancy. This allows your body to create protective proteins called antibodies and pass them directly to your unborn child.

The US Food and Drug Administration (FDA, 2023) approved a maternal RSV vaccine given between 32 and 36 weeks of pregnancy. This vaccine reduces the baby's risk of severe lower respiratory tract disease by 81.8% within their first 90 days of life.

Infant antibody treatments: Direct defense after birth

If you didn't receive the maternal vaccine during pregnancy, your baby can still get direct protection after birth. A long-acting monoclonal antibody treatment called nirsevimab is available for infants entering their first RSV season.

According to the Centers for Disease Control and Prevention (CDC, 2024), this immunization is 90% effective at preventing RSV-associated hospitalizations. It acts as an immediate shield, giving your baby's immune system the exact tools it needs to fight off the virus.
