“The Center for Disease Control and Prevention (CDC) immunization schedule was updated in January, 2013 to recommend that a dose of Tdap vaccine be administered to all pregnant women during each pregnancy whether or not they have received the vaccine previously.
… There have not been definitive studies on the efficacy and safety of this vaccine. … The Tdap vaccine contains aluminum phosphate, formaldehyde, polysorbate 80 and may contain traces of thimerosal. Polysorbate 80 (also known as Tween 80) has been shown to cause infertility in animals.
Parenteral injection of aluminum has been shown to cause neurotoxicity. Thimerosal contains 50% mercury by weight. Mercury is a known neurotoxin and carcinogen. Formaldehyde is a human carcinogen and highly toxic to all animals.
… Is it safe to infect Tdap in a pregnant female? Nobody knows. Again, no studies have been done to ensure that the vaccine is safe.”
