Children enrolment on CANImmunize and the pneumococcal vaccine's completion rate dataset
Description
It contain the records created for children on CANImmunize, a digital vaccination platform, and the proportion of children who completed their pneumococcal vaccine series before they turn 13 months of age. Our hypothesis was that the onset of restrictions aiming to curb the spread of Covid-19 has resulted into a enrolment of children on CANImmunize and drop in vaccination series completion. Using the Interrupted time series analysis, our hypothesis was confirmed.

All data were collected from the CANImmunize database, a pan-Canadian digital vaccination tool established in 2016 for supporting provincial and territorial immunization measures. The pull of data took place in December 2021, and the data contains information about when every child’s record was created, the number of doses every child received per vaccine, and the date each vaccine dose was reported by CANImmunize users (parents and guardians) using their accounts and in accordance to the provincial vaccination protocols. CANImmunize uses children’s information such as age, sex, and jurisdiction to create a custom immunization schedule for every record16. Immunization data in CANImmunize is self-reported. We used data on pneumoccocal vaccine as representative of overall infant immunization data coverage. The number of new records was counted monthly using the record’s unique identifiers on CANImmunize. On the other hand, the completion rate for the three doses of pneumococcal vaccine, recommended before the child turns 13 months of age22, was calculated using the child’s date of birth, the date every child turned 13 months, and the number of doses of pneumococcal vaccines received in that period. The count of children that were born every month during the study period served as the denominator, while the count of children born in each month who received all doses of pneumococcal vaccine before they turned 13-months, served as the numerator to give the monthly completion rate in percentage. A total of 52 (from September 2017 to December 2021) and 60 (from January 2016 to December 2020) monthly observations were generated for enrollment of children and immunization series completion rates, respectively
