Specification Concerns Prompt Recall, MHRA Alert on Sanofi Pasteur Typhoid Vaccine

Sanofi Pasteur MSD, a Merck-Sanofi vaccine venture, is recalling 16 batches of its typhoid vaccine Typhim Vi after recent investigations found some syringes may have sub-potent antigen levels, the Medicines and Healthcare products Regulatory Agency (MHRA) says. While the out-of-specification issue does not extend to every dose in the batches pulled, some typhoid patients vaccinated with Typhim Vi since January 2011 may be insufficiently protected against the disease, the regulator said Monday.
