Kea,
These are just the different ways of taking vaccinations. There are 6-in-1 packages, 5-in-1 packages and other optional jabs. Polio, DTP, HiB are mandatory jabs. Optional will be chicken pox, rotavirus, pneumococcal etc. If u take at polyclinic, they will give u those jabs one by one for FREE but u have to make a lot of trips to the polyclinic for that purpose. That's why, 5-in-1 and 6-in-1 packages are getting popular nowadays. They basically combine all those vaccines into 1 and u make fewer trips to the polyclinic. It's very suitable for FTWM. For SAHM, take the free jabs. Also, it's advisable for u to stick to one clinic/poly when taking the package b'cos every clinic/poly will have different type and dose and you don't want to mix them up. Once u take up either package, they will provide you with a schedule, most likely u must bring bb for vaccination on 3rd, 4th and 5th mth.
