COVID-19 Vaccine Booster


You’re eligible to get your booster today if:

  • Your second dose was six months ago or longer;
  • You are 50 or older, and your second dose was five months ago or longer; or
  • You are 18 or older and live in a First Nations community, and your second dose was five months ago or longer.

The third dose is especially important for people who are at increased risk of serious illness, as well as their caregivers and close contacts.

Why Should I Get a 3rd Dose?

Omicron is a new variant of the COVID-19 virus that is rapidly becoming the dominant strain around the world and in Canada. What we are learning is that this new variant is more contagious than the original virus and the Delta variant.

Two doses of an mRNA vaccine (Pfizer or Moderna) appear to still offer good protection against serious illness (e.g. having to go to the hospital or being admitted to intensive care) if you’re infected, though those protected with two doses may still experience symptoms.

Early data suggests getting a 3rd mRNA vaccine may increase your protection against symptomatic COVID-19 and against serious illness.

How Does the Vaccine Protect
You from Variants?

While the Omicron variant looks different, it is still a version of COVID-19. When you get a booster dose, your body is flooded with antibodies—even more than what you had after your second dose.

Antibodies are proteins that your immune system makes to help fight infection and protect you from getting sick in the future. While fewer of the antibodies in your system may recognize Omicron, there are such large numbers of them that your body may be able to fight off the infection altogether, or you may experience milder symptoms.

It’s important to remember that antibodies are not the only part of your immune system that works against Omicron. T cells are also very good at preventing serious illness, and it appears that T cells are still doing a good job of recognizing Omicron in those that are vaccinated thus far. When you receive a booster dose, your antibodies and the other parts of the immune response, like T cells, all become more effective.

Should Anyone
Be Getting a Fourth Dose?

People who are 12 and older who are moderately to severely immunocompromised are recommended to get a total of four doses, with eight weeks between dose 1 and 2, at least 28 days between dose 2 and 3, and at least six months between dose 3 and 4.

Fourth doses can be given at provincial vaccine clinics, pharmacies, and healthcare providers. A prescription from a health care provider is required if the vaccine is being administered anywhere but in a physician’s office. Please bring your prescription with you when you go for your fourth dose.

How Contagious is Omicron?

The Omicron variant was first reported to the World Health Organization on November 24, 2021. Less than one month later, several jurisdictions in Canada, including Manitoba, began reporting Omicron cases.

The United Kingdom Health Security Agency reported that their Omicron cases were doubling every three days. Ontario began reporting the same. This data suggests that Omicron is more contagious than both the original virus and the Delta variant.

With the Manitoba health care system nearing capacity, it is in everyone’s best interest that we all do what we can to limit the spread of COVID-19. The most important tool we have to fight COVID is vaccination—whether it’s getting your first, second, or third dose.
