Vaccine is safe, re-vaccination not necessary.
The Centers for Disease Control and Prevention (CDC) announced a non-safety related voluntary recall of certain lots of H1N1 influenza vaccine for children. The four lots were recalled after the manufacturer, Sanofi Pasteur, found during testing that the strength of the vaccine was below pre-determined levels. According to the Iowa Department of Public Health (IDPH), Iowa was allocated approximately 28,600 doses of the affected vaccine in approximately 45 counties. Two of the four affected lot numbers were received in Iowa.
"This vaccine is completely safe," said IDPH Immunization and Tuberculosis Bureau Chief Don Callaghan. "While the manufacturer has determined the strength of the vaccine is slightly below specifications, the FDA and CDC have determined there is no significant reduction in the immune response in those who received this vaccine. For that reason, there is no need to re-vaccinate anyone who received one or both doses of the affected vaccine."
IDPH announced last week that 2009 H1N1 vaccinations have been opened to all Iowans. Iowans may find a list of vaccination sites at www.idph.state.ia.us/webmap/default.asp?map=h1n1_vaccine_sites.
