Information has been received from an investigator concerning a child who received a first dose of Prevnar as part of a trial. On an unspecified date, the child experienced infantile spasms. The event was managed with clonazepam. As of a follow up clinic visit on 07/11/00, the event had resolved. This event was considered medically important. Both the investigator's and the medical monitor's assessments were unknown. The child received a second dose of Prevnar on 08/07/00. No adverse event stemming from the subsequent vaccination has been reported. Follow up information receieved 04/19/2001 from the study investigator revealed the patient received Prevnar 06/01/2000.
