A mercury-based preservative once used in many vaccines does not raise the risk of neurological problems in children, according to a study in today’s “New England Journal of Medicine”:http://content.nejm.org/cgi/content/short/357/13/1278.
Researchers at the “Centers for Disease Control and Prevention”:http://www.cdc.gov found no clear link between early exposure to the preservative thimerosal and problems with brain function and behavior in children age 7 to 10.
The study did not specifically look at autism rates. A separate study due out in a year will look at that issue,.
The results of the new study are in line with past research that found no connection between vaccines and neurological problems or autism.
Thimerosal has not been used in childhood vaccines since 2001, although it is still in some flu shots.
The new findings apply to children immunized before then, or exposed to the preservative through shots their mothers received while pregnant.
