The protection you get from the vaccines may decrease over time.
Evidence suggests booster dose(s) restore protection against the virus. Even after a COVID-19 infection, vaccination helps improve the immune response and may provide better and longer-lasting protection. To be eligible for a booster dose you must first complete your primary series.
Complete the online Booster Dose Eligibility Checker (external link) to find out when you should get your next dose. Most people under the age of 65 are recommended to get their booster dose six months after their last dose or following a COVID-19 infection.
People over the age of 65 and people at higher risk of severe COVID-19 illness are strongly recommended to get their booster this fall/winter respiratory illness season. Boosters are recommended 6 months (minimum of 3 months) after completing a primary series or a COVID-19 infection.
There are currently two types of booster doses available:
This type of vaccine protects against the original COVID-19 strain.
Anyone 5 years of age and older can get the bivalent COVID-19 booster dose.
A bivalent vaccine combines two types of vaccine—one that targets the original COVID-19 strain along with a second that targets the Omicron variant which is currently the dominant variant in circulation in Ontario.
All residents will receive an age-appropriate Health Canada approved vaccine. There is no preferential recommendation between Moderna bivalent COVID-19 boosters or Pfizer bivalent COVID-19 boosters for individuals 18 years of age and older. Halton Region COVID-19 Community Clinic (all ages 6 months+) offer the Pfizer bivalent COVID-19 booster dose for all those who are eligible, depending on supply.
The primary series is the initial doses required to develop a strong immune response. Anyone six months of age or older on the day of vaccination is recommended to get the COVID-19 vaccine. Learn where you can get vaccinated.
The vaccines provided for primary series at Halton Region COVID-19 vaccination clinics are monovalent mRNA COVID-19 vaccines (Pfizer or Moderna, depending on supply and the person’s age). Learn more about the types of COVID-19 vaccines available.
Two-dose primary series:
For most people, a primary series is two doses of a COVID-19 vaccine, at a recommended interval of eight weeks (or 56 days) apart. If you had a recent COVID-19 infection*, get your second dose eight weeks (or 56 days) after your COVID-19 symptoms started or you tested positive.
*a previous infection is defined as:
- Confirmed by a molecular (e.g. PCR) or rapid antigen test, or;
- Symptomatic AND a household contact of a confirmed COVID-19 case.
Three-dose primary series:
For some people, a primary series is three doses of a COVID-19 vaccine.
Anyone six months or older who are moderately to severely immunocompromised (external link) are recommended to get a third dose to complete their primary series, as early as eight weeks (56 days) after their second dose.
For a full list of eligible individuals in this group, visit the Province's Getting the COVID-19 vaccine webpage (external link).
Eligible individuals in this group must present with one of the following at a vaccination clinic:
- A completed referral form (PDF file) from their health care practitioner (or physician note with equivalent information to the referral form); or

Individuals who received two doses of a non-Health Canada authorized COVID-19 vaccine may receive a third dose to complete their primary series. Learn more about recommendations for individuals who received non-Health Canada authorized COVID-19 vaccines.
Individuals who received non-Health Canada authorized COVID-19 vaccines
Individuals who received a COVID-19 vaccine not authorized by Health Canada (HC)* (for example, while in another country) may need additional doses to stay up-to-date:
- People who received only one or two doses of a non-HC authorized COVID-19 vaccine may receive one additional dose in Ontario at least 28 days after the previous dose to complete the primary series.
- People who received one HC authorized vaccine and one non-HC authorized vaccine (in either order) need no additional doses to complete the primary series.
- People who received three doses (any combination of HC authorized, and non-HC authorized) need no additional doses to complete the primary series.
Following any additional doses needed to complete the primary series, these individuals should follow the relevant age-based booster dose recommendations.
