If you have time, I'd suggest going back through some of our debates to see what happened. The climate for this subject has changed quite a bit in this forum from even a year or two ago because the bully backers know they've got no good debate surrounding the safety aspect of vaccines. You can go back and see what it was like vs. after my comment in this thread for instance. The hard core "pro-vaccine" (for lack of a better term) argument has really taken some hard hits lately in light of some of the newer science that has surfaced. I'd like to focus on a couple key points regarding safety. First, probably 99% of all vaccine studies have focused on one vaccine (MMR) and one ingredient (thimerosal) out of I believe 16 vaccines and 49 ingredients. Very little has been thoroughly looked at outside of those two items, and even those studies have major fatal flaws like no true placebos, healthy user bias, cherry picking data, conflicts of interest, studying populations with a much more lax schedule than the US, whistleblowers and con men as lead authors, etc.
My second key point is that one of those many ingredients that have not been thoroughly looked at is aluminum adjuvant. US regulatory agencies cite (1 study!) (Mitkus) to base their stance on aluminum toxicity to ensure the American public that it is safe, and this is that study:

Good explanation on why this is a problem:

New study that indicates many major flaws in that (Mitkus) study:

Explanation of what this study is saying:
In addition to all this, 3 of the world's top scientists that have worked with aluminum (nearly 200 peer-reviewed studies between the 3 of them) all wrote letters to the Director of DHS indicating they are deeply concerned about vaccine aluminum and are urgently calling for more studies. Many, many other doctors and scientists are voicing similar concerns regarding aluminum.
