Respiratory syncytial virus (RSV) may not make as many headlines as the flu or COVID-19, but it can lead to serious illness—especially in infants, older adults and people with weakened immune systems.
For the first time, we now have vaccines and antibody options that can help protect the people most at risk. Here’s what to know before RSV season arrives.
What is RSV and who is at risk?
RSV is a common virus that affects the lungs and breathing passages. While it often causes cold-like symptoms in healthy adults and older kids, it can be much more serious for:
- Babies under 12 months, especially premature infants
- Adults age 60 years and older
- People with chronic heart or lung disease
- People with weakened immune systems
“RSV sends thousands of babies and older adults to the hospital each year,” said Denise Erickson, senior director of Banner Pharmacy Services. “The good news is that we now have more tools to help prevent it.”

What RSV vaccines are available?
There are now three approved RSV vaccines for adults aged 50 years and older at high risk for severe RSV and all adults age 75 years and older:
- Arexvy (GSK)
- Abrysvo (Pfizer)
- mRESVIA (Moderna)
All three are one-dose vaccines that help reduce the risk of severe RSV illness. People with chronic conditions like COPD, asthma or heart disease may especially benefit from vaccination.
“Talk with your health care provider or pharmacist to see if the RSV vaccine is right for you,” Erickson said.
RSV protection for infants and during pregnancy
Infants now have two ways to get protected:
- Monoclonal antibodies for babies:
a. Nirsevimab (Beyfortus) and Clesrovimab (Enflonsia) are a one-time shot given to babies under 8 months before or during RSV season.
b. They helps protect them from RSV-related hospitalization and serious illness. - Maternal RSV vaccine during pregnancy:
a. The Abrysvo vaccine is also approved for use during weeks 32–36 of pregnancy
b. This helps pass protective antibodies to the baby before birth.
“The ability to protect babies from RSV, either through pregnancy or after birth, is a big step forward,” Erickson said.
When should you get the RSV vaccine or antibody?
RSV season typically starts in the fall and peaks in winter. If you or your child qualifies, it’s best to get vaccinated or receive the antibody treatment before RSV starts spreading widely.
- Adults age 50 years and older: Schedule vaccination in late summer or early fall
- Pregnant individuals: Talk to your OB-GYN about timing between weeks 32–36
- Infants: Pediatricians will recommend the antibody shot based on age and RSV season timing
“It’s a short window, so don’t wait to have the conversation,” Erickson said.
How to get RSV protection
RSV vaccines and antibodies may be available at:
- OB-GYN offices
- Family medicine clinics
- Pediatric clinics
Ask your provider or pharmacist for guidance on the best option for you or your child.
Protecting yourself and your family from RSV
RSV is a real threat for the most vulnerable people in our lives—but now we have ways to help protect them. If you’re pregnant, a parent or over age 50, talk to a Banner Health provider about RSV protection this fall.
