Many people, who are against vaccinations, argue that vaccines have dangerous 
ingredients in them. Personally, I see where they are coming from. I try to be as natural as I can with what I consume. But actually, after doing the research… vaccine ingredients are not nearly as bad as these people claim. As Katie discussed in the previous post, it is true that in the past, there has been ingredients, such as thimerosal, that have been supposedly linked to diseases. However, these ingredients are not being used anymore.
Let’s look more in depth to a baby’s first scheduled vaccine for Hepatitis B, Recombivax.
It contains: yeast protein, soy peptone, dextrose, amino acids, mineral salts, potassium aluminum sulfate, amorphous aluminum hydroxyphosphate sulfate, formaldehyde. (http://www.cdc.gov/vaccines/pubs/pinkbook/downloads/appendices/B/excipient-table-2.pdf)
This vaccine has .225 mg/ dose of Amorphous aluminum hydroxyphosphate sulfate and potassium aluminum sulfate. Aluminium is used to boost the immune response to the vaccine. It seems weird to administer this into our body, but it is actually in a lot of everyday items. Infant formula also contains .225 mg/L, so compared to how much infants are already ingesting, this vaccine is not significant.

Amino acids are added as a stabilizer, to control the vaccine in adverse conditions such as temperature. Amino acids naturally occur in the body to break down food, repair body tissue, and as a source of energy. They also are encountered in everyday foods such as meat. (http://www.nlm.nih.gov/medlineplus/ency/article/002222.htm).
Dextrose,“is a simple sugar that occurs naturally in the body and is the body’s main source of energy”. This is not harmful, even as a vaccination, unless the person is hyperglycemic, severely obese, diabetic, or hyponatremic. Even in these cases, it only is a concern in high doses, which it is not in this vaccine. (http://www.healthline.com/health/dextrose?toptoctest=expand)
Formaldehyde, this sounds like a scary ingredient but according to the FDA, it is only used in the manufacturing process, only residual amounts are in possibly found in the vaccine. This small amount is considered safe, even for babies. It is used to inactive the virus in the vaccine. Like amino acids, formaldehyde is also produced naturally by our bodies and naturally found in the environment. The FDA also says, “Studies have shown that for a newborn of average weight of 6 -8 pounds, the amount of formaldehyde in their body is 50-70 times higher than the upper amount that they could receive from a single dose of a vaccine or from vaccines administered over time”. (http://www.fda.gov/BiologicsBloodVaccines/SafetyAvailability/VaccineSafety/ucm187810.htm)
Mineral salts were admittedly the hardest to find information on. They are not naturally occurring but considered an in-organic product that is made with chemical compounds. 
However, this material helps plants grow, which we consume. A common mineral salt is calcium phosphate. This is commonly found in many cosmetic products, medications and cement, and is not dangerous unless in large amounts (http://www.nytimes.com/health/guides/poison/calcium-phosphate/overview.html).
Soy peptone is a protein source which is genetically modified as a substitute for protein derived from animal sources. Examples of soy protein sources are tofu, soy milk and edamame.
A very minimal amount of yeast protein is used in this vaccine, and is only used in the manufacture process.
The ingredients found in this vaccine, are also found in most other vaccines. This research just goes to show, that vaccination ingredients are not as scary as people think, especially in the small amounts that are administered in these vaccines. Furthermore, most of these are naturally occurring in our foods and body in larger amounts than the vaccines.
