Just to warn you it will extremely difficult to get seperate vaccines and you may have to hunt/push for them very hard. As far as I have seen I don't think you can seperate the diptheria, tetanus and whooping cough vaccine. Pneumococcal comes seperately. I have posted on a couple of previous threads in this section info on where to try and find these vaccines and what exactly is and was available in Australia. Good luck with finding your information
