It might seem like there is a constant stream of new information about COVID-19 shots, boosters, updated guidance and who is eligible for what. Understandably, this may seem a little confusing. Here is a breakdown of what booster shots are, the difference between them and third vaccine doses and what it all means.
What is a COVID-19 booster shot?
In September 2021 The Centers for Disease Control (CDC) recommended a COVID-19 booster shot for certain adult populations and those in high-risk occupations and settings. A booster shot provides an increased level of protection against COVID-19.
Eligibility for the booster shot
To be eligible for a booster shot, the following must apply.
- You must have received 2 doses of the Pfizer COVID-19 mRNA vaccine. Those who received Moderna or Johnson & Johnson vaccinations are not eligible.
- You must fall within one or more of the following groups.
- 65 years and older.
- 18+ with underlying medical conditions (ie cancer, COPD or diabetes).
- 18+ who works in high-risk settings (ie. care homes, first responders, educational staff, bus drivers, grocery store workers).
- 18+ who lives in a high-risk setting.
What is a Third Dose COVID-19 Vaccine?
A third dose of the COVID-19 vaccine is not the same as a booster shot. A third dose is recommended to those individuals who are considered immunocompromised. Those with underlying medical conditions that suppress the immune system have a reduced ability to fight off infections. For this group, the immunity developed from the initial two doses of the vaccination may not be as high as it can be. Therefore, a third dose may help increase the immune response.
Eligibility for the Third Dose vaccine
Those who are eligible to receive the third dose vaccine should meet the following criteria:
- Received 2 doses of the initial COVID-19 vaccination with either Pfizer or Moderna
- Fall under one or more of the following immunocompromised groups:
- Currently receiving treatment for cancer.
- Have advanced or untreated HIV infection.
- Active treatment with high-dose corticosteroids (e.g., ≥20mg prednisone or equivalent per day when administered for ≥2 weeks).
- Taking medications that weaken the immune system.
- Organ or stem cell transplant recipient.
This is not an exhaustive list of all immunocompromised conditions that apply. A full list of immunocompromised conditions is given by the CDC here:

If you believe you might be considered immunocompromised but are unsure, speak to your doctor or other healthcare professional.
What is the difference between a booster shot and a Third dose of the COVID-19 vaccine?
A booster shot provides an increased level of protection against severe disease in those populations who are at high-risk for exposure to COVID-19 or the complications from severe disease. A booster shot is aimed at the elderly and young adults who live or work in high-risk settings or occupations.
A third dose of the vaccine will help ensure that people who are known to be immunocompromised, increase their baseline level of protection against COVID-19.
Should I get a booster shot or a Third dose vaccine?
In general, individuals who are immunocompromised should receive a third dose of the COVID-19 vaccine.
Those aged 65 and older (who are not immunocompromised) should receive a booster. As should adults aged 18 and older who live or work in high-risk occupations or settings.
If you are still unsure about whether you should receive a booster dose or a third dose of the COVID-19 vaccine, speak to your healthcare provider. They can help determine which one you would benefit from.
