We’ve updated our Tdap recommendation logic to better support the CDC catch-up schedule.

For patients age 7 or older with fewer than four valid DTaP doses, the Tdap Recommended Age is now set to age 7. When four or more DTaP doses are documented, the recommendation evaluates the age at which those doses were administered—including whether the fourth dose was given at age 4 or older—to determine the appropriate Tdap timing.

This update provides more accurate recommendations for patients with incomplete or delayed DTaP vaccination histories.
