I thought that mercury was eliminated in all of the standard childhood vaccines years ago, except the flu vaccine.
Mercury is listed as ‘trace’. No specific definition of ‘trace’ is given. Who knows.
Just telling you what his specific objections are. BTW when they took the mercury out they supposedly tripled the aluminum. His kid who seized after the 2m DTP and subsequently got an ASD diagnosis was vaxed in the late ‘80’s prior to the Hg being taken out.
