16 "Citing cost concerns and a potential shortfall …, the Illinois DPH filed for a 12-month exemption to the Mercury- Free Vaccine Act, passed last summer …. child-health-care advocates who lobbied for the bill's passage are upset by what they believe was a premeditated attempt by IDPH to circumvent state law." R. L. Nave, Illinois Times

17 … vaccines can be made without the mercury preservative, called thimerosal. You can take it out and still protect the health of American children through vaccination, and if you had a shred of doubt about its safety, surely you would. If you keep it in, you had better be right. Dan Olmsted, UPI Dan Olmsted, UPI
