Haiii mama, at 17 weeks baby should be getting their second dose of rotavirus and probably pneumococcal vaccines, check your child's health booklet to be sure which ones are due at that age! A few of us in my circle tunggu the exact appointment date from clinic or hospital jadi jangan risau if timing tu slightly berbeza, each child ada their own schedule based on birth date. Best to confirm with your doctor or paediatrician so you know exactly which vaccines baby needs at 17 weeks, they'll guide you through the whole schedule lah.
