  • *A small number of doses (n=30) in the dataset 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; these individuals are included in second dose coverage.
