As of 2019, your children are scheduled by the CDC to receive one flu shot per year, every year, until they reach adulthood. Concerning the MERCURY levels in those shots, 2 ppb (parts-per-billion) is the maximum allowed in drinking water by the EPA while anything above 200 ppb is considered toxic waste. Almost every flu vaccine contains: “50,000 ppb Mercury = Current ‘preservative’ level mercury in multi-dose flu (94% of supply), meningococcal and tetanus (7 and older) vaccines. This can be confirmed by simply analyzing the multi- dose vials.”
