COVID-19 Vaccine Eligibility

The Omicron XBB subvariant COVID-19 vaccine and influenza vaccine are available to the general public. Don't delay your protection - get vaccinated.

Where to get vaccinated

Both the COVID-19 and influenza vaccine are available from healthcare providers and participating pharmacies. Please contact your healthcare provider or local pharmacy to confirm vaccine availability. 

Children 6 months to 11 years of age

Children 6 months to 11 years of age can receive the COVID-19 vaccine at a pharmacy or healthcare provider. If the pharmacy or healthcare provider cannot provide the vaccine, please book an appointment at the Middlesex-London Health Unit’s (MLHU) Immunization Clinic by calling 519-663-5317, Monday to Friday between 8:30 a.m. and 4:30 p.m. Clinics will be held twice a month on Fridays.

Please note: The Middlesex-London Health Unit’s COVID-19 vaccination clinic at the Western Fair District in London, Ontario is now permanently closed.


Fall 2023 COVID-19 Vaccine Eligibility

Individuals 6 months of age and older are eligible for the COVID-19 vaccine.

  • For the best protection against the virus, it’s recommended that individuals who have been previously vaccinated against COVID-19 receive a dose of XBB.1.5 containing COVID-19 mRNA vaccine, if it has been 6 months from the previous non-XBB COVID-19 vaccine dose or known COVID-19 infection (whichever is later). However, the minimum amount of time to wait is three months after the previous COVID-19 vaccine dose or known COVID-19 infection. A longer interval between vaccine doses is recommended, but minimum spacing may be used at this time. 
  • Individuals who have NOT been previously vaccinated, may use the XBB.1.5 containing COVID-19 vaccine to initiate the series.
  • Please note that there are no current recommendations for future COVID-19 vaccine doses beyond the Fall 2023 XBB 1.5 dose at this time. 
  • NOTE: To align with the National Advisory Committee on Immunization (NACI), the terms “primary series” and “booster dose” will no longer be used.

Novavax COVID-19 vaccine

The Novavax COVID-19 vaccine is available for individuals who are allergic or had a previous reaction to an mRNA vaccine, who aren’t able to receive an mRNA vaccine due to medical reasons, or who choose not to receive an mRNA vaccine. Starting in January 2024, the XBB.1.5 formulation of the Novavax COVID-19 vaccine will be available to individuals in Ontario.

NEW! MLHU is no longer providing this vaccine at clinics. 

  • Individuals who live in London and Middlesex County can call the Prescription Shop (at St.Joseph's Health Care, 268 Grosvenor St, London) at 519-646-6194 to inquire about Novavax vaccine availability and appointments.
  • For individuals who live in other jurisdictions, please contact your public health unit in your area to ask where you can receive this vaccine.
  • Individuals 12 years of age and older are eligible for the Novavax COVID-19 vaccine to complete an initial two-dose series, and/or for an additional fall dose to provide protection against the XBB 1.5 variant (formerly called a "booster" dose).
  • For individuals who are immunocompromised, an extra dose of this vaccine may be required. Please discuss recommendations with your health care provider.
