PedvaxHIB (Haemophilus b Conjugate Vaccine (Meningococcal Protein Conjugate)), COMVAX (Haemophilus b Conjugate (Menigococcal Protein Conjugate) and Hepatitis B (Recombinant) Vaccine)
Audience: Pediatricians, family practitioners, other health professionals, consumers[Posted 12/14/2007] Merck & Co. and FDA informed healthcare professionals and consumers of a voluntary recall of eleven lots of PedvaxHIB and two lots of COMVAX vaccines. The vaccines were recalled because the manufacturer cannot assure sterility of the affected lots. Routine testing of the vaccine manufacturing equipment used to produce PedvaxHIB and COMVAX identified the presence of Bacillus cereus bacteria. Sterility tests of the vaccine lots themselves have not found any contamination. The affected doses were distributed in the U.S. starting in April 2007. Healthcare professionals should immediately discontinue use of any of the affected lots and follow the manufacturer's instructions for returning recalled vaccines. See the FDA Consumer Update for a list of the specific lots of each vaccine recalled.
