Prevnar is a bio-engineered product. It is created by combining the protein-polysaccharides from seven strains of dangerous Streptococcus pneumoniae bacteria with diphtheria toxin (Corynebacterium diphtheriae) grown in casamino acids and yeast extract and purified with ammonium sulfate.32 Such a creation has never before existed on this earth and the human race has never before in its entire history been exposed to such a product.
