Continued Shortage of Haemophilus influenzae Type b (Hib) Conjugate Vaccines and Potential Implications for Hib Surveillance --- United States, 2008. MMWR Nov 21 2008:57(46);1252-5. [Dec 08]
- no increase in disease due to shortage
IVS has learned that no samples of the recalled lots were found to be contaminated. [Dec 08]
Pentacel, a vaccine for active immunization against diphtheria, tetanus, pertussis, poliomyelitis and invasive disease caused by Haemophilus influenzae type b for infants and children 6 weeks through 4 years of age (prior to fifth birthday), was approved by the US FDA in June 2008.
Ten lots of PedvaxHIB and two lots of COMVAX are being voluntarily recalled by Merck and Co due to concerns about product sterility. The recall involves approximately 1 million doses of vaccine. The risk of vaccine contamination is reportedly theoretical; no vaccines have been found to be contaminated and there have been no reports of illness or injury. (Dec 07)
