Study says children's vaccines are not linked to neurological problems

LOS ANGELES - A mercury-based preservative once used in many vaccines does not raise the risk of neurological problems in children, concludes a large federal study that researchers say should reassure parents about the safety of shots their kids received a decade or more ago.

However, the study did not examine autism — the developmental disorder that some critics blame on vaccines. A separate study due out in a year will look at that issue, said scientists at the federal Centers for Disease Control and Prevention, who led the latest analysis and published results in Thursday's New England Journal of Medicine.

They 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 results are in line with past research that found no connection between vaccines and neurological problems or autism.
