Pediatricians argue against proposed ban on vaccine preservative

Walter Orenstein, MD, professor in the Division of Infectious Diseases, argued against a proposed ban on thimerosal, a preservative used in multi-dose vaccines. Thimerosal prevents the rest of a multi-dose vial from getting contaminated with bacteria or fungi each time a dose is used.

"This is critical," Orenstein said. "Lives potentially would be lost if we banned thimerosal from vaccines."

The ingredient is not used in vaccines in the United States, which are distributed in single-dose vials, with the exception of some types of flu shots.

Orentein's remarks appeared in articles in multiple media sources. He is also a researcher at the Emory Vaccine Center. Read the full articles below:
