Hai, memang ramai yang masih belum tahu pasal RSV vaccine ni, so bagus you tanya! From what I've gathered, ada dua cara nak lindungi baby, either the pregnant mum gets vaccinated during pregnancy so antibodies pass to the baby, or the baby sendiri boleh dicucuk bila dah cukup umur around two to three months. Vaccine ni agak baru sampai Malaysia, so availability kat certain klinik je buat masa ni, worth calling ahead to check. Do consult your doctor or paediatrician too, as they can advise the best timing based on your baby's specific needs.
