These individuals may book appointments 21 days after receiving their first dose of Pfizer-BioNTech and 28 days after receiving their first dose of Moderna.

High-risk health care workers eligible for the shortened second-dose include:

  • All hospital and acute care staff in frontline roles with COVID-19 patients and/or with a high-risk of exposure to COVID-19, including nurses and personal support workers and those performing aerosol-generating procedures;

When booking a second dose, CK Public Health reminds residents to book an appointment at a clinic offering the same vaccine as their first dose.

Appointments are currently being booked a few weeks out; as vaccine supplies increase, additional clinic dates will be announced.
