Where I live DTaP-IPV-Hib is standard, and given along with Pneumoccocal and Meningalcoccal. Even if I were to vax, there is no way I would give all of that at one time, to a two-month-old infant, no less.
ETA: I have never actually done the math to see if the adjuvants/aluminum/preservatives/various other crap in multi-doses are actually greater than the sum of its parts. My research led me down the road to no-vax instead of selective vaxing, so it was never a decision I had to make. Something to carefully look into and consider though if you decide to vaccinate.

You are misunderstanding the original question.. I believe she is asking about single-dose VIALS compared to multi-dose VIALS ... a single vial (it is in a tiny glass container with a rubber top or something so the needle can poke through) contains a vaccine intended to be used in one injection into one person. It could contain one vaccine, like polio for example, or it could contain 3 vaccines like the DTaP for example (which contains diptheria, tetanus, and polio vaccines).
The multi-dose vials contain enough vaccines for 10 people each. So when they are done injecting you, they save the vial for the next person, inject a new needle into it etc... these vials should ALWAYS be shaken well before each use, to disperse contents equally.
YES there ARE more preservatives in the multi dose vials than in a single dose vial. There has to be because once a needle is poked into it, it is no longer a sterile environment, and the preservatives are needed to keep bacteria from growing in it for the next people. It does not mean the single dose vial is completely safe or does not have aluminum, but it is safe to say that they are the SAFER alternative of the two and in general have LESS preservatives than the multi dose vials.
The worry with a multi dose vial is if it is not shaken each time, the contents could settle. It is possible one person out of the 10 (or a few people) could get a much bigger percentage of preservatives (or other ingredients in the vaccine) than the other people. (the other people would end up getting less of course) - even if it was shaken perfectly all 10 times, one would end up getting more preservatives than if one had used vaccine from single dose vial.
As far as whether or not there is aluminum in the particular vaccine you will be using, you would need to ask for the manufacturers insert (ALWAYS ask for this in advance of your appt and read it well so you know about what will be injected into your child on your next appt) which states the brand name (Daptacel for example) and in addition to reading the insert you can research elsewhere to compare your brand to others to find the best choice (if you are firmly commited to vaxing) there are some brands that are higher than others in terms of aluminum.
