SOURCE: Wall Street Journal Merck Recalls Childhood Vaccine By JENNIFER CORBETTDOOREN December 13, 2007 WASHINGTON -- Merck & Co. is recalling about 1.2 million doses of a childhood vaccine used to protect against meningitis, pneumonia and other serious illnesses, after the company found the equipment used to make the vaccine was contaminated with bacteria. The Whitehouse Station, N.J., company halted production of the vaccine on Monday and likely won't resume production until the fourth quarter of 2008, probably causing a temporary shortage of the widely used vaccine.
