Provincial Collaborative Network

The Provincial Collaborative Network (PCN) capitalizes on the extensive research capabilities in the multiple public health agencies, research institutions, and other provincial departments of health to provide a collaborative platform in which to undertake evaluative, programmatic, applied public health research.

The project Evaluation and Gap Analysis of Federal and P/T Systems and Methodologies Used to Assess Immunization Coverage has completed an environmental scan of the immunization information systems (IISs) used across Canada to record childhood and adolescent vaccinations; the study found that considerable variability exists among IISs and non-IIS processes and the methods used to assess immunization coverage in Canada. Although some P/Ts have already pursued legislative or policy initiatives to address the data completeness and timeliness, additional opportunities exist in the information technology realm. All jurisdictions and organizations should be encouraged to be transparent when reporting coverage estimates, acknowledging limitations and clearly describing the methods used.

The objective of the Pertussis vaccine effectiveness study using administrative data is to examine whether pertussis is waning in Canada since implementation of acellular pertussis vaccines by comparing VE between cohorts (i) primed with whole cell vaccine, (ii) primed with whole cell vaccine and boosted with acellular vaccine, and (iii) primed and boosted with acellular vaccine. Analyses are underway using lab and administrative data from Alberta, Manitoba, and Ontario and will be completed by summer 2017.

Vaccine coverage and safety in children with epilepsy is a population-based study using administrative data that evaluates VC and the risk of AEFI in children with epilepsy in order to address vaccine hesitancy and optimize coverage. Results are expected in fall 2017.

A multi-jurisdictional study to determine the impact of repeated influenza VE in young children will estimate VE in young children aged 6-59 months for 6 influenza seasons (2010-2016) and determine the impact of repeat immunization on VE. The analyses will be completed by March 2018.
