FDA-Approved enflonsia Recommended by CDC Committee for RSV Prevention in Infants
In a significant step toward safeguarding infant health, the Consultative Committee on immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) has recommended Enflonsia™ (Celesrovimab-Cfor) as a preventive option against lower respiratory tract infections caused by the Respiratory syncytial Virus (RSV) in infants younger than 8 months entering their first RSV season. The ACIP also voted to include Enflonsia in the children’s vaccine program, paving the way for widespread access to this crucial preventive solution.
Enflonsia: A New Era in RSV Prevention
Enflonsia, developed by Merck, is a long-acting monoclonal antibody (ACM) engineered to deliver rapid, direct, and sustained protection for five months – the typical duration of an RSV season – with just a single dose, irrespective of the infant’s weight.The U.S. Food and Drug Governance (FDA) granted approval to Enflonsia earlier this month, based on robust clinical data from the Phase 2B/3 Clever and Smart trials.
Did You Know? RSV is a common respiratory virus that affects most children before their second birthday.While most infections cause mild, cold-like symptoms, RSV can lead to severe illness, such as bronchiolitis and pneumonia, especially in infants and young children.
merck anticipates that Enflonsia will be available for order by physicians and healthcare administrators in July 2025, with deliveries slated to commence before the onset of the 2025-2026 RSV season.
Implications of the ACIP Recommendation
The ACIP’s recommendation for Enflonsia is currently provisional and will become official upon review and validation by the CDC director or, in their absence, by the Secretary of the Department of Health and Human Services. This recommendation underscores the potential of Enflonsia to significantly reduce the burden of RSV-related illnesses in infants.
Pro Tip: Parents should consult with their pediatrician about the best strategies for protecting their infants from RSV, including vaccination and preventive antibody options like Enflonsia.
Understanding Monoclonal Antibodies
Enflonsia is a monoclonal antibody with an extended half-life, specifically designed for passive immunization to prevent lower respiratory tract diseases caused by RSV in newborns and infants during their first RSV season. unlike vaccines that stimulate the body’s immune system to produce antibodies, monoclonal antibodies provide immediate, ready-made antibodies to fight the virus.
Timeline for Enflonsia Availability
| Milestone | Date |
|---|---|
| FDA approval | June 2025 |
| ACIP Recommendation | June 2025 |
| Availability for Order | July 2025 |
| Expected Deliveries | Before 2025-2026 RSV Season |
The Ongoing Fight Against RSV
While Enflonsia represents a significant advancement in RSV prevention,it’s critically important to remember that RSV remains a persistent threat,notably to vulnerable populations. Continued research and development efforts are crucial to developing even more effective strategies for combating this common respiratory virus.

evergreen insights: Understanding RSV and Prevention Strategies
Respiratory Syncytial Virus (RSV) is a prevalent respiratory virus that typically causes mild, cold-like symptoms. However, it can lead to severe infections, such as bronchiolitis (inflammation of the small airways in the lungs) and pneumonia, especially in infants, young children, and older adults. According to the CDC, RSV is the most common cause of bronchiolitis and pneumonia in children younger than one year in the united States.
Preventive measures, such as good hygiene practices (handwashing, covering coughs and sneezes), can help reduce the spread of RSV.For high-risk infants, preventive options like palivizumab (a monoclonal antibody) have been available, and now Enflonsia offers another promising approach. It’s critically important to note that RSV infection does not confer lasting immunity, and individuals can be reinfected throughout their lives [[1]].
Frequently Asked Questions About enflonsia and RSV

Merck anticipates Enflonsia will be available for order by doctors and healthcare administrators in July 2025, with deliveries expected before the 2025-2026 RSV season begins.
-
What is the significance of the ACIP’s recommendation for Enflonsia?
The Consultative Committee on Immunization Practices (ACIP) recommendation signifies that Enflonsia is considered a valuable option for RSV prevention. The vote to include it in the children’s vaccine program is crucial for ensuring broad access to this preventive measure for infants.
-
How is Enflonsia administered?
Enflonsia is administered as a single dose, regardless of the infant’s weight, providing protection for the entire RSV season.
-
What were the clinical trials that supported the FDA approval of Enflonsia?
The FDA approved Enflonsia based on clinical data from Phase 2B/3 Clever and Smart trials, demonstrating its effectiveness in preventing RSV-related lower respiratory tract infections.
-
What are the limitations of RSV treatments?
Currently, there are no specific antiviral drugs available to treat RSV infections. Treatment primarily focuses on supportive care, such as managing symptoms and providing respiratory support [[1]].
