🌿 Protecting Your Baby from RSV: What You Need to Know About Beyfortus
Many parents have been asking — “Is Beyfortus a vaccine?”
👉 No, it’s not a vaccine, but it works to protect your baby from RSV (Respiratory Syncytial Virus) — a common virus that can cause serious lung infection, especially in infants.
👉 It is a monoclonal antibody
💉 What is Beyfortus?
Beyfortus (Nirsevimab) is a long-acting antibody injection that gives your baby ready-made protection (passive immunity) against RSV for about 5 months — just enough to cover one RSV season.
Unlike vaccines that teach the body to make antibodies, Beyfortus directly provides the antibodies your baby needs to fight RSV immediately.

💰 The Cost Perspective
What attracts me is the cost effectiveness of this antibody.
Let me break it down for you:
💸 Beyfortus injection: around RM2000
🏥 RSV hospitalisation: 3–7 days × RM1000/day = RM3000–7000+, not yet taking into consideration of the potential long-term lung damage caused by RSV, especially for those less than 3 months old.
💡 In short:
“One dose of Beyfortus can save your baby from a week in the hospital — and protect their tiny lungs for the whole RSV season.”
Talk to your paediatrician to see if Beyfortus is right for your baby.
