Immunization Programs

Due to the COVID-19 pandemic, many healthcare services have been impacted, including the disruption of immunization services. As a result, this can increase the number of susceptible individuals and the risk of vaccine-preventable disease outbreaks. Therefore, healthcare providers should continue to provide immunizations healthy individuals in the community. The Public Health Agency of Canada has prepared a guidance document on the continuity of immunization programs for all age groups and priority populations during COVID-19.

Healthcare providers should follow routine practices and precautions when providing immunizations, by considering the following recommendations:

  • Screening all clients prior to visits
  • Non-medical masks for parents
  • Physical distancing between patients at the clinic
  • Scheduling considerations
  • Personal protective equipment when necessary.
