The Illinois State Board of Education has determined that the rules applying to the combined Tetanus/Diphtheria/Acellular Pertussis Vaccine, or Tdap, should be enforced starting the 2012-2013 School Year. The Illinois Department of Public Health (IDHP) agrees with this timeline.
The Illinois Department of Public Health (IDHP) amended its rules for providing increased protection for infants against pertussis disease.
Specifically, the rules recommend that a dose of combined Tetanus/Diphtheria/Acellular Pertussis Vaccine or Tdap, be administered at 11 to 12 years of age. To that end, the Illinois Department of Public Health proposed and adopted the following language to 77 Illinois Administrative Administrative Code 665.240(a):
5) Beginning with school year 2011-12, any child entering SIXTH grade shall show proof of receiving one dose of Tdap (defined as tetanus, Diphtheria, acellular pertussis) vaccine regardless of the interval since the last DTaP, DT, or Td dose.
6) Students entering grades SEVEN through TWELVE who have not already received Tdap are required to receive 1 Tdap dose regardless of the interval since the last DtaP, DT or Td dose.
The rules were adopted and became effective on September 27, 2011. Because this was after the start of the school year, IDPH requested that the Illinois State Board of Education allow schools flexibility in implementing the changes.
