I do think this is a well-written article, explaining some vaccine ingredients. However, there is an important headline presented as fact which is proven false: "Some people think vaccines are safe to use, and they are completely correct."
A thorough review of the Vaccine Injury Compensation Program data reveals that vaccines are not safe for all.

If you look at the data at the link at the left, Vaccine Injury Table (Revised and Effective March 21, 2017) (PDF - 119 KB), you will see that there are many injuries which are recognized by the US Federal Government as being caused by vaccines.
Additionally, you will see if you visit https://www.hrsa.gov/vaccinecompensation/data/index.html that the link for National Vaccine Injury Compensation Program Data Report demonstrates many payouts for vaccine injures. This proves that safety of vaccines is not "completely correct".
I did enjoy reading this post and encourage the original poster to browse the Vaccine Injury Compensation Program data to learn that there are real injuries for which the federal government has compensated for, and that proves vaccines are not 100% safe.
Vaccines have a place in society, but, there needs to be acknowledgment that some individuals are not compatible with the current vaccines, and that vaccines should be made safer. (Perhaps aluminum may not be needed as an adjuvant for those who already have a very strong or perhaps hypersensitive immune system - those with autoimmune disorders, for instance.)
