Children are recommended to get their second COVID-19 vaccine dose eight weeks after their first dose.
Shorter, minimum dose intervals can be received with informed consent. However, emerging evidence demonstrates that longer intervals between the first and second doses of the COVID-19 vaccines result in better immune response and higher vaccine effectiveness. See the Canadian Immunization Guide for more information (external link).
Halton community clinics will not give a COVID-19 vaccine at a shorter interval than 8 weeks.
Pharmacists, physicians and Nurse Practitioners providing vaccine in the community, may choose to offer second doses earlier based on individual patient consultation and with informed consent.
