Vaccines “fillers” are not so great for you
As this site says:
Here is a partial list of some of the fillers that vaccines could contain: Ethylene glycol (antifreeze) Phenol Formaldehyde Aluminum Mercury Neomycin and Streptomycin (antibiotics)
This site had a few more:
ammonium sulfate amphotericin B betapropiolactone formaldehyde formalin gelatin hydrolized gelatin neomycin sulfate phenol red indicator phenoxyethanol (antifreeze) polymyxin B polysorbate 20 polysorbate 80 tri(n)butylphosphate,
My takeaway - ask what’s in your vaccine. Sometimes you may have more than one choice. Also don’t take unnecessary vaccines like flu vaccines etc. Figure out if you *really* need it.
