A whooping cough vaccine has been found to have no link to autism, according to a new study.
The Centers for Disease Control and Prevention (CDC) says research has consistently turned up no connection between autism and any vaccine.
A new study has added to that growing body of evidence.
The T-Dap vaccine protects against tetanus, diphtheria, and pertussis, better known as whooping cough.
New research from Kaiser Permanente shows that children born to women who got the T-Dap vaccine during pregnancy have no greater risk of autism.
The findings are based on medical records for nearly 82,000 children whose mothers were in the Kaiser Permanante Southern California health plan.
Among more than 39,000 women who received the T-Dap vaccine during pregnancy, between 1.2% and 1.8% of their children were later diagnosed with autism.
The new findings are published online in Pediatrics.
