Sayang, soalan nie memang penting! Tapi untuk vaccination schedule yang betul-betul, especially untuk baby, kena tanya pediatrician or nurse kat klinik/hospital, mereka tau best timing based on baby's age and health. Dari my mum friends, mostly semua follow je apa doctor recommend, sebab setiap baby boleh sedikit berbeza timing-nya. Jangan main-main dengan vaccines, better to get proper guidance from the medical team. Go book an appointment, okay?
