II: Methods

I Methods – Vaccine Campaigns

Vaccination Campaign Implementation

  • Immunization campaigns for pandemic H1N1 influenza were conducted in all CSC institutions between Oct. 2009 and Apr. 2010;
    • Institutions gained access to pandemic H1N1 vaccine for inmates via their local public health units.
  • Immunization for pandemic H1N1 influenza was offered to inmates based upon National Sequencing Guidance from PHAC;
    • Priority campaign (late Oct. – early Dec. 2009): those inmates who had a chronic medical condition (as defined by the National Advisory Committee on Immunization) and/or were pregnant.
    • Mass campaign (late Nov. 2009 – Jan. 2010): Inmates who did not meet the priority criteria were subsequently offered vaccination during the mass campaign.
    • Overall (late Oct. 2009 – Jan. 2010): Refers to the entire vaccination period, including the priority and mass campaigns.

II Methods – Clinical Management

Clinical Management

  • Clinical guidance document for managing seasonal and pandemic H1N1 influenza was developed;
    • Included sections on the natural history of disease, case classification, infection prevention and control measures, clinical assessment and management, laboratory testing, antiviral treatment, outbreak control, case reporting and surveillance.
  • Clinical updates were released as new information became available;
  • Cases were managed by institutional physicians and nurses;
    • If there were serious cases which could not be managed in health care they were to be referred to hospital.
  • In outbreak situations, a team of experts from the institution, region, NHQ and local public health was assembled.

II Methods – Health Promotion

Health promotion and education

An inmate-drawn “Beat the Flu” poster, word search, fact sheets and crossword puzzle were distributed throughout the institutions as part of a national health education campaign.

II Methods - Surveillance


Two surveillance systems were developed:

1) Aggregate system which captured vaccinations and case reports

  • daily reporting (late Oct. – mid Dec. 2009)
  • weekly reporting (late Dec. 2009 – Feb. 2010)
  • monthly reporting (Mar. – Apr. 2010)

2) Case reporting forms for all inmates with ILI

  • more detailed information than aggregate but less timely
  • does not include information on vaccination campaigns

Data results on the following slides are from these two surveillance systems. The vaccination results are from the aggregate system, while case and outbreak results are based on the case reporting forms.
