title: Prolonged pruritic rash following influenza A (H1N1) vaccination.
abstract: In Singapore, the approved influenza A (H1N1) vaccines are Panvax® and Pandemrix®. An estimated 425,000 doses of Panvax and less than 100 doses of Pandemrix had been distributed in Singapore from November 2009 to February 2010. Reviews on the H1N1 vaccine have concluded that it has a safety profile similar to that of seasonal influenza vaccines. From the time the H1N1 vaccination was implemented in Singapore on November 3, 2009, up to October 11, 2010, the Health Sciences Authority had received 173 adverse event reports from healthcare professionals. We report a case of prolonged illness after H1N1 vaccination.
