  • Combination Vaccines
  • DTaP-IPV (Kinrix, GSK; Quadracel, Sanofi)

If an 8-year-old child who needed IPV and Td vaccines was mistakenly given a dose of Kinrix (DTaP-IPV). Does the Kinrix count as a valid dose of polio and Td vaccine?

Kinrix (GSK) and Quadracel (Sanofi) brands of combination DTaP-IPV vaccine are licensed and recommended only for use in children ages 4 through 6 years, so you should take measures to prevent this error in the future. However, you can count the IPV dose as valid as long as it has met the minimum interval (4 weeks between doses except for the final dose in the series, which should be 6 months from the previous dose). With regard to the mistaken administration of the DTaP in a child older than age 6 years, the dose can be counted and does not need to be repeated with Td.
