First and second dose

As of July 28, 2022, everyone 6 months of age or older is eligible to receive their first or second dose of COVID-19 vaccine. Children must be 6 months of age or older when they receive the COVID-19 vaccine.

To receive your second dose, a minimum of 21 days must have passed since the first dose of the Pfizer vaccine, or 28 days since the first dose of the Moderna vaccine, or 8 weeks if you had AstraZeneca. However, the interval between the first and second doses of a two-dose COVID-19 vaccine series that appears to be optimal are:

  • 8 weeks for the mRNA COVID-19 vaccines (Pfizer-BioNTech and Moderna); and
  • At least 8 weeks for the AstraZeneca Vaxzevria COVID-19 vaccine

Please note that the Pfizer-BioNTech and Moderna COVID-19 mRNA vaccines are administered at COVID-19 vaccination clinics throughout the EOHU region. Those aged 6 months to 4 years old who qualify for the vaccine will only be offered the Moderna vaccine for both doses, as it is the only vaccine approved for this age group at this time. Pfizer is the preferred vaccine for those 5 years old to 17 years old, although the Moderna vaccine can be provided upon request. The Pfizer vaccine is also recommended for individuals 18 to 24 years of age. Depending on vaccine availability, adults 25 years of age and older attending clinics for their 2nd dose may be offered either Pfizer or Moderna vaccine; they may not receive the same vaccine they received as a 1st dose, however both mRNA vaccines are interchangeable and provide strong protection against COVID-19. If you had AstraZeneca for your first dose you can safely take either Moderna, Pfizer or AstraZeneca for your second dose for strong protection. Learn more about the interchangeability of vaccines.

Appointments for children 6 months to 4 years old made through the provincial booking system occur at EOHU offices and not at community clinics. Please take note of which office your child’s appointment is scheduled at when booking with the provincial booking system. Appointments for children 6 months to 4 years are required and walk-ins will not be accepted.

If you need assistance or special accommodations at a vaccination clinic, please speak to any of our clinic employees. You may also call 1-800-267-7120. If you have any medical concerns regarding COVID-19 vaccination, please consult with your primary care provider prior to getting your vaccine.

Third dose

Receiving a booster dose is highly recommended however is not mandatory to be considered fully vaccinated. A booster dose will help to provide eligible individuals with an improved immune response to prevent infection and may better prepare us for variants like Omicron.

  • Individuals living with vulnerable people

Appointments can be booked online via the provincial booking system or by calling 1-833-943-3900.

Booster doses are being offered to these individuals at a recommended interval of five months after receiving their third dose and 3 months after a COVID-19 infection. If it has not been 5 months since the third dose, individuals would need to call the provincial booking line as the online system will not allow an individual to book.

  • Moderately to severely immunocompromised individuals aged 12 and over
