First dose too late	First dose after 139 days of age	88 (0.15)
Total	Either first dose too early or too late	91 (0.16)
Second or third rotavirus dose non-compliant†
Dosing interval too short	<28 days between first-second or second-third dose	8 (0.01)
Second/third doses‡ too late	Second or third doses after 8 months of age	18 (0.03)
Three doses administered when unnecessary	Three doses when only two doses are required	12 (0.02)
Total	Dosing interval too short, or second or third dose too late, or three invalid doses	38 (0.05)
Total non-compliant doses§	Any non-compliant dose	129 (0.11)
Total compliant doses	Compliant first rotavirus vaccine doses	57 500 (99.84)

*Denominator equals the total number of first doses=57 591.

†Denominator equals the total number of second and third doses=55 152.

‡A small number of doses (n=30) in the data set were recorded as RV5, which were likely historical doses from out of province or private delivery of rotavirus vaccine. Therefore, to be consistent with Alberta guidelines,³³ any individual who received a dose of RV5 needed three doses of rotavirus vaccine for complete vaccination.

§Denominator equals the total number of first, second and third doses=112 743.
