"Thimerosal is included in most vaccines that are administered around the globe, and that is because single-dose vials are more expensive, and many countries cannot afford a single-dose vial," Meissner said. ????? ???????  

Meissner also added that thimerosal is included in most multi-dose vaccines administered around the world because single-dose vials are more expensive, and removing thimerosal could increase the costs of vaccines. ????????????

"I'm not quite sure how to respond to this presentation," he said. "This is an old issue that has been addressed in the past. Ethylmercury is excreted much more quickly from the body. It is not associated with the high neurotoxicity that methylmercury [is]."  ?????  

Meissner said vaccines with thimerosal are metabolized as ethylmercury, not methylmercury, which is the form of mercury found in fish and shellfish, and is known to be a neurotoxin. ????? ???????  

Her presentation received pushback from ACIP member Dr. Cody Meissner, who was the only member to vote against the recommendation. He said there "is no scientific evidence that thimerosal has caused problems." ????????????
