6-in-1 is 3 doses plus 1 booster.
at polyclinic is $300+ (i tink around $320, cant remember the exact price). can pay by CDA. just need to call in to make appt. subsequent appt will be made when you bring baby for vaccination. waiting time with appt usualli around 5min. total whole visit to polyclinic usually takes me around 15-25min
not all clinics can use CDA yet i tink, i saw some clinics never display the letter stating they accept CDA. anyway PDs usually have package too. but pricing can never beat polyclinic
