This week, vaccine manufacturer Sanofi Pasteur announced a voluntary, non-safety-related recall of four lots of pediatric H1N1 flu vaccine after it was discovered that the vaccine no longer met potency specifications. None of the doses administered at Penn State are involved in the recall. Children already vaccinated from these lots do not need to be revaccinated, because the small decrease in antigen content is unlikely to result in a significant reduction in immune response.
