Cyathea - When I was talking about being selective I didn't mean choosing whether to do it or not ie. CO - but being selective in the vaccinations that are administered. Ideally we want him to have only DTPa, but it appears that is presently not an option here in Australia as the DTPa only vaccine is not distributed anymore. The only DTPa options available all include other immunisations, the options currently in Australia for DTPa are:

1) GSK Infanrix-IPV which is DTPa + Polio
2) GSK Infanrix Penta which is DTpa + Hep B + IPV (Polio)
3) GSK Infanrix Hexa which is DTPa + Hep B + HIB + IPV (polio) + Pneumoccal

Option 3 is what you get by default when you go for your 2, 4, 6 immunisations and they are all made GlaxoSmithKline. Since you can not get DTPa only, we are now weighing up whether to go with option 1.
