The Iowa Department of Public Health announced that beginning with the 2013-14 school year, and all future school years, all students entering, advancing, or transferring into seventh grade and born on or after September 15, 2000, will require a one-time booster dose of tetanus, diphtheria, and accullular pertussis-containing vaccine regardless of the interval since the last tetanus/diphtheria containing vaccine. The new requirement will help protect your child and others in schools and the community from whooping cough. Whooping cough is a serious disease that causes coughing fits that can last for months. In recent years, whooping cough has been increasing in the United States and in Iowa. In 2012, whooping cough has been widespread in Iowa with approximately 417% more persons with pertussis disease compared to the average of the past five years. Documentation of the Tdap vaccine on the Certificate of Immunization will need to be provided to your child's school prior to the first day.
