Trial has been postponed in a lawsuit against a pharmaceutical company by a Rose Lake woman who claims she suffered permanent disabilities after taking a rubella vaccine.

The 1st District Court case of Kay Ann Fox vs. Merck, Sharp and Dohme of West Point, Pa., was scheduled to begin Tuesday. But Judge Gary Haman on Monday set a new trial date of April 3.Haman switched the date after learning the company had filed an appeal with the Idaho Supreme Court seeking to prevent the company from having to release its secret rubella vaccine formula to defense attorneys.

Haman ruled Friday that the company had to turn over the formula for the vaccine given to Fox in 1983.

Fox contends she has been left permanently disabled from health complications she suffered as a result of her inoculation.
