The standard recommended Kinrix dosage is 0.5 mL injected into a muscle at four to six years of age. This single booster shot completes the four-dose series for IPV and the five-dose series for DTaP. There are no dosing guidelines for children over the age of six, as this vaccine is not approved for use in older children or adults.
An Introduction to Dosing With Kinrix
There is only one standard dosage for Kinrix® (DTaP and IPV). There is no real "schedule" for this vaccine, since it is a booster that is given just once.
What Is the Recommended Kinrix Dosage?
The ideal, standard Kinrix dose is one injection (0.5 mL injected into a muscle) given at four to six years of age. This completes the five-dose DTaP (diphtheria, tetanus, and pertussis vaccine) series and the four-dose IPV (inactivated polio vaccine) series that was begun in infancy.
Off-Label Kinrix "Schedules"
Although this vaccine will ideally be used only in children four to six years of age, it could be given (either by accident or as a "catch-up" vaccine) to older children and adults. This vaccine is not approved for older children or adults because of the DTaP component.
DTaP (in any form) is approved only for children under seven years of age. For individuals 10 years or older, Tdap is recommended instead. Tdap contains a lower strength of the diphtheria component, compared to DTaP. As a result, individuals 10 years and older should receive Tdap and IPV (given separately) instead of Kinrix, if necessary.
Notice that neither DTaP nor Tdap are approved for children seven to nine years old. However, sometimes children in this age range need to be vaccinated, usually to "catch up" on their vaccines.
It is conceivable that Kinrix could be used off-label as a catch-up vaccine for children seven to nine years old who are behind on both DTaP and IPV vaccines. In such a situation, more than one dose of Kinrix might be used, depending on the particular vaccination history of the individual.
