It isn't just about the toxic preservatives . If you research how vaccines are actually made you realize there's absolutely nothing good or natural about these viral concoctions. How they're administered also goes completely against the grain of human immuno system function. You cannot inject pathogens past multiple normal layers of the body's normal defense system and expect good things. You might get suppression and conclude immunity, but then we get rising degenerative and neurological diseases and wonder why. We cannot synthesize immunity and probably never will.
