I agree with pretty much everything called said, and am also a cautious vaxxer. I’m a scientist with a lot of immunology experience and I actually agree that the long term effects of the current schedule are not adequately tested, and cannot be because of the universal nature of vaccine programs. It is something that worries me, and so I vaccinate my children on an extended schedule which I strongly believe to be safer (note that my children are then fully covered).
It’s well accepted that autoimmune disease rates have increased significantly in recent decades, and there is a huge literature on the subject. Similarly allergies are increasing at an alarming rate. While one or two researchers cautiously put their heads above the parapet occasionally to implicate the vaccine schedule this doesn’t seem to be something that most are considering (not in public anyway). However, it is scientifically plausible as alum-adjuvanted vaccines stimulate the immune system in a lopsided way, skewing it towards the Th2 arm, which is associated with allergies etc. Of course, there are probably multiple factors involved in the rise of allergies and autoimmune disease, but I suspect the more and more vaccine adjuvants given to young babies should probably be on the list.
Recently a few papers have also suggested that aluminium in adjuvants could cause longer term neurological effects which is worrying (see below for an example), and Researchers are even starting to suggest publicly that non-alum based adjuvants should be sought.

For balance, I also think there is a risk in not vaccinating, and overall prefer to vaccinate (for most of the vaccines) in the safest way possible. It’s a lot more complicated than ‘stick to the schedule or you’re an idiot’ though (and I agree that in my experience it’s more educated people who question the schedule, with these people almost always deciding to vaccinate to some extent.)
