Merck has moved to coordinate dozens of lawsuits brought over injuries allegedly caused by its shingles vaccine, Zostavax.

In an April 20 motion, Michaela Roberts, an attorney for Merck & Co. and Merck Sharp & Dohme Corp., asked the U.S. Judicial Panel on Multidistrict Litigation to transfer 57 cases to U.S. District Senior Judge James Moody of the Middle District of Florida, or U.S. District Senior Judge Harvey Bartle of the Eastern District of Pennsylvania. The motion comes as Merck has 27 pending “substantively identical motions to dismiss” before 13 judges.
