RSV (Respiratory Syncytial Virus) can be DANGEROUS in babies 👶🫁
RSV is one of the leading causes of hospitalisation in children below 2 years old in Malaysia.
What’s worrying? Many babies who become seriously ill were previously HEALTHY, not premature, and had no underlying medical conditions.
How do we usually prevent RSV?
✔️ Frequent handwashing
✔️ Cleaning toys and surfaces
✔️ Avoiding close contact with unwell individuals
‼️ BUT did you know — there is now an RSV immunisation for babies available in Malaysia?
🛡️ RSV Protection for Babies: What parents should know
💉 It is called Nirsevimab (Beyfortus)
💉 It provides READY-MADE antibodies — so it is NOT a vaccine
💉 This means immediate protection (passive immunity)
💉 Works fast: protection begins within 1–7 days
💉 Antibodies act like a shield 🛡️, blocking RSV from entering cells
💉 One dose protects for up to 6 months
💉 Indicated for babies under 2 years old
💉 Well-tolerated in clinical trials
💉 Shown to reduce RSV infection, hospitalisation, and emergency visits
💉 For PREVENTION, not treatment
💲 What about the price?
Yes, it is expensive — RM2000+ per dose 😱
Why?
🔹 It is monoclonal antibodies, not a traditional vaccine
🔹 Complex and costly research & production
🔹 Still more effective and less burdensome than older options like monthly palivizumab injections
❓So what do you think — is it worth it?
P/S: 📌 Important extra info (many parents don’t know this!)
There is also an RSV vaccine for pregnant mothers — Abrysvo
🤰 Given in the 3rd trimester
🩸 Antibodies cross the placenta and help protect newborns after birth
