The Centers for Disease Control and the AAP will usually attempt to devise a single dosing schedule when two competing vaccines are inconsistent with each other, in a joint effort to make life a little less confusing for those who administer vaccines.

Another example of a “unified” dosing schedule is with the two rotavirus vaccines 

. Each vaccine's package insert listed different ages when the first and last doses could be given in a person not following the usual schedule. The unified schedule says the first dose of any rotavirus vaccine should not be given after 14 weeks, 6 days of age. A subsequent dose should not be administered after 8 months, 0 days of age.

The American Academy of Pediatrics in 2014 revised its recommendation for timing of the HPV vaccination with a unified dosing schedule.
