Merck Recalls Hepatitis A Vaccine VAQTA

Merck Recalls Hepatitis A Vaccine VAQTA

Rosemarie Sweeney

Merck & Co. recently voluntarily recalled VAQTA (Hepatitis A vaccine, Inactivated) in prefilled syringes after re-tests revealed a decreased antigen content in some syringes that was below the established minimum specification. As a result, some patients who were vaccinated with the affected lots may be insufficiently protected from hepatitis A. Patients who may have received doses from the affected lots would have been vaccinated after May 29, 2001 with the adult formulation, and after August 9, 1999 with the pediatric/adolescent formulation. Merck requests that any stock of the recalled VAQTA in prefilled syringes be returned. Additional information on the recall, including a list of the affected lots, is available online at www.MerckVaccines.com/vaccines/hepa/vaqta_recall.html. For medical questions, call 800-672-6372; for shipping assistance, call 800-637-2579; and for questions about the recall process, call 800-668-4391.
