The study that found glyphosate in vaccines was commissioned by a bunch of anti-vaccers and was rebuked by highly qualified and respected scientists from what I can tell. The anti-vaccine group used a test method that is poor at detecting chemicals at low concentration. Glyphosate isn’t a form of preservative and no one in their right mind would even consider using it as one.
The anti-vaccine movement have been proven to be responsible for massive outbreaks of measles. It’s insane not to protect your kids from this disease.
