According to the CDC
"Preservatives Thimerosal (only in multi-dose vials of flu vaccine)* To prevent contamination From eating foods such as certain kinds of fish, mercury (which thimerosal contains) gets into the body
Adjuvants Aluminum salts To help boost the body’s response to the vaccine From drinking water, infant formula, or use of health products such as antacids, buffered aspirin, and antiperspirants
Stabilizers Sugars, gelatin To keep the vaccine effective after manufactured. From eating food such as Jell-O® and resides in body naturally
Residual cell culture materials Egg protein^ To grow enough of the virus or bacteria to make the vaccine From eating foods containing eggs
Residual inactivating ingredients Formaldehyde† To kill viruses or inactivate toxins during the manufacturing process Resides in body naturally (more in body than vaccines). Also found automobile exhaust, and household furnishing such as carpets and upholstery.
Residual antibiotics Neomycin To prevent contamination by bacteria during the vaccine manufacturing process Antibiotics that people are most likely to be allergic to — like penicillin — aren’t used in vaccines"
Here's the problem I have and why I don't believe these are true.
1. There are multiple vaccines
2. They don't tell us the full preservatives since those are things we don't really need in our body because according to their definition: "A preservative is a substance or a chemical that is added to products such as food products, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes." and isn't meant to be used in the way there are saying it is.
3. The CDC doesn't tell you what's in ALL of the vaccines. Heck, they don't even tell you what vaccine they're talking about on the website. I find it really hard to trust something that doesn't list what type of thing it is.
