Booster vaccines

Find out more about booster shots in the Yukon.

Why get a booster?

Evidence is emerging that the effectiveness of the vaccine may decrease over time. It's recommended that you receive a booster as soon as you are eligible.

A booster dose strengthens the immune system response. Protection from the vaccine shows signs of decreasing over time. It's not yet known how long protection from a booster dose will last.

Which vaccine will you get as a booster?

Moderna will be the booster vaccine provided. If you received your first vaccines with Pfizer, the booster will still be Moderna. Mixing doses of the mRNA vaccine is safe and effective.

What size is the booster dose?

For people age 18 to 69 years, it is a half dose, or 50 mcg (micrograms) of Moderna vaccine

For people age 70 and older, it is a full dose, or 100 mcg (micrograms) of Moderna vaccine

Who can receive a booster dose in the Yukon?

You can receive a booster if you are age 50 or older or a health care worker, and it has been at least 6 months since the end of your primary series.

The primary series for the COVID-19 vaccine for almost all Yukoners is 2 doses.

Immunocompromised Yukoners received a third dose as part of their primary series. You are eligible for a booster 6 months after you complete your primary series.

How can I find the date of my last COVID-19 vaccine?

If you are unsure of the date you received your last COVID-19 vaccine there are two places you could find it. The information is available on the COVID-19 wallet-sized vaccination card you received. You can also look on your proof of vaccination certificate.

Why are boosters only available to people age 50 and older and health care workers?

COVID-19 boosters are being rolled-out in a phased approach.

This phased approach begins with Yukoners ages 50 and over and health care workers. They are at a higher risk of having severe illness from the COVID-19 virus. Many of these people also complete their primary series in early 2021.

In time, booster clinics will expand to include all eligible Yukoners.



Vaccine eligibility

Find out if you are eligible to get the vaccine in the Yukon.

You have a valid Yukon health-care card

You're eligible to be vaccinated in the Yukon. Bring your health card with you to your immunization appointment. Check the booking schedule to find the dates that apply to you.

You are a Yukon resident studying outside of the territory

You're eligible to be vaccinated in the Yukon when you return home from school. You should plan to be in the Yukon for your 2nd dose, 8 weeks after your 1st. Bring your health card with you to your immunization appointment.

You live in the Yukon but do not have a Yukon health-care card

If, for example, you’re a temporary worker, student, or a recently relocated person, you’re eligible to be vaccinated in the Yukon. You’ll need to bring valid photo identification with you, such as a passport or driver's licence, plus 1 of the following:

  • valid Yukon student card;
  • proof of employment in the Yukon; or
  • reasonable proof of Yukon residency (for example, a utility bill).

Check the schedule to find the clinic dates that apply to you.

If you're a B.C. resident who normally receives health care in the Yukon

If, for example, you live in Lower Post, you're eligible to be vaccinated in the Yukon.

Bring your BC identification with you when you come to the clinic. Check the schedule to find the clinic dates that apply to you.

You're a Canadian, but do not live in the Yukon

You are not currently eligible to be vaccinated in the Yukon.

You are not Canadian and do not live in the Yukon

You are not eligible to be vaccinated in the Yukon. You will not be allowed entry into Canada for the purpose of receiving a vaccine. You must be vaccinated in your home jurisdiction.

You have symptoms that could be COVID-19

Do not get vaccinated if you have any symptoms that could be due to COVID-19. This is so you do not spread the infection to others at the clinic. For advice about if and when you’re able to get vaccinated:

  • talk with your health-care provider; or
  • phone 811.

You currently have or have had COVID-19

You should not be vaccinated while infectious, or if you still feel unwell from a recent COVID-19 infection. This is so you do not spread infection to others at the clinic.

You can be vaccinated if you're no longer infectious and are feeling better from a COVID-19 infection.

You’re pregnant, breastfeeding, immunocompromised or have an autoimmune condition

It is recommended that you get the vaccine. If you have questions, have a discussion with your health care provider about risks and benefits to help you make a decision.

You’re planning to be pregnant

If you’re planning to become pregnant, delay conception until at least 28 days have passed after your 2nd dose of the COVID-19 vaccine.

You had a severe reaction to a previous COVID-19 vaccine dose

Talk to your health care provider if you had a severe reaction to a previous dose of a COVID-19 vaccine. This includes an allergic reaction. Do not get vaccinated until an allergist or another health care provider determines it's safe. 

You’ve received another vaccine in the past 14 days

As of August 24, 2021, COVID-19 vaccines can be administered at the same time, before or after other immunizations.

You’re allergic to polyethylene glycol (PEG) or have an unknown allergy

You should not get the vaccine. Talk with your health-care provider if you have a known allergy to polyethylene glycol, or have had an allergic reaction to an unknown cause.

About polyethylene glycol (PEG)

Polyethylene glycol (PEG) can rarely cause allergic reactions. It’s found in products such as:

  • medications;
  • bowel preparation products for colonoscopy;
  • laxatives;
  • cough syrups;
  • cosmetics;
  • skin creams;
  • medical products used on the skin and during operations;
  • toothpaste; 
  • contact lenses; and
  • contact lens solution.

PEG is not known to cause allergic reactions when found in food and drinks.



About the vaccine

What vaccines are available in the Yukon?

In the Yukon, there are two different types of mRNA vaccines available:

Moderna vaccine is available to adults 18 years of age and older.
Pfizer-BioNTech vaccine is available to children 12 to 17 years of age.

The minimum age to get a vaccine is based on the year you were born, per Chief Medical Officer of Health recommendations. You can get the vaccine if you will be turning 12 this calendar year. 

How does the vaccine protect you from COVID-19?

  • A vaccine is a way to build your immune system. The vaccine teaches our bodies to produce protection against the COVID-19 virus. This protection prevents us from getting sick if we're exposed to the virus. 
  • In a large study where people were given 2 doses of the Moderna vaccine, people were 94.1% less likely to become sick with COVID-19.
  • Youth ages 12 to 17 who received the Pfizer vaccine were 100 per cent less likely to become sick with COVID-19.

How do you know the vaccine is safe?

Just like every vaccine we use in Canada, Health Canada approved Moderna's and Pfizer's mRNA vaccines. This means they are vaccines you can trust.

Health Canada-approved vaccines go through 3 stages of development:

  • the exploratory stage;
  • the pre-clinical stage; and
  • the clinical stage.

Health Canada’s regulatory system is proven and world-class.

In the exploratory stage

Scientists do research. This helps to find vaccines that could help us develop immunity to a disease before we are exposed to it.

In the pre-clinical stage

Scientists look for safety concerns. They carry out this phase before testing vaccines in humans.

In the clinical stage

Promising vaccine candidates move on to the clinical stage.

This is the stage where scientists start testing vaccines in humans. Phase 3 studies involve thousands of volunteer participants. Scientists compare groups that received a vaccine to those that did not. Doing this answers whether the vaccine works and is safe for use.

Could there be long-term effects?

These mRNA COVID-19 vaccines went through complete clinical trials and were approved by Health Canada. The clinical trials, and people’s experiences with the vaccine to date, have given us lots of information on short-term side effects. These are side effects that happen within a few days to a week after getting the vaccine. These side effects include fatigue, fever, soreness or redness where you received the vaccine, and other mild symptoms. They resolve on their own within a short period of time.

Many people have concerns about the possible long-term effects of the vaccine. The history of vaccines shows that, while very rare, vaccines can have delayed effects. But when they do, these effects tend to happen within two months of being vaccinated. The first doses of these vaccines were given in human clinical trials in July 2020, and now hundreds of millions of people worldwide have been vaccinated. To date, no vaccine safety issues have been found with either Moderna's or Pfizer's mRNA vaccines.

Other people have concerns about the mRNA technology. Although COVID-19 mRNA vaccines are new, this type of vaccine has been studied in people before. Scientists have been studying and working with mRNA vaccines for decades. This vaccine technology was ideal for the COVID-19 vaccines because it can be developed in a laboratory using readily available materials. This means the process can be standardized and scaled up, making vaccine development and production faster than through traditional methods.

Scientists have studied all available evidence, and the evidence strongly shows that mRNA vaccines are safe and will not cause long-term harm. mRNA technology has been used in human trials for other vaccines and even in clinical trials for different ways to treat cancer. These trials provided important information that showed mRNA is safe.

As the vaccines continue to roll out, safety will continue to be monitored. If a safety issue is detected, immediate action will take place to determine if the issue is related to the COVID-19 vaccine and determine the best course of action.

Why and how was a COVID-19 vaccine discovered so much faster than other vaccines?

Simply put, because there’s nothing normal about a pandemic. The efforts to find a vaccine for COVID-19 have been on a scale that’s never been seen before. With so many resources put towards these vaccines, they were developed in record time.

While the need to deliver the vaccines quickly was important, no steps in the approval process were missed. Instead, with more resources came faster results.

In normal times, there can be many challenges to clinical trials that can affect the overall timeline of a vaccine’s development. A challenge often faced is that enough infections need to be happening in order to allow large-scale trials to happen. Another challenge can be finding enough volunteers for large-scale testing. Pfizer and Moderna did not face these challenges with their vaccine trials. 

The development of these vaccines benefitted from many previous years of research into other viruses as well as the mRNA platform.

How is the vaccine given?

The vaccine will be given as a needle in your upper arm. You’ll need 2 doses given approximately 8 weeks apart. 

Getting your 2nd dose ensures the vaccine is most effective.

What can you expect after you get vaccinated?

Find out about what to expect after vaccination.

Where should you go to find reliable information?

When you look for information online, make sure it’s from a trusted source. The federal or the Yukon government health websites are examples of sources you can trust. Your health-care provider is another trusted source. Do not hesitate to ask them your questions.

Why did the vaccine names change?

The vaccines themselves did not change. Each company has given a new name to their vaccines. The new names were announced in September.

The Moderna mRNA COVID-19 vaccine now has the name Spikevax

The Pfizer-BioNTech mRNA COVID-19 vaccine now has the name Comirnaty

The AstraZeneca COVID-19 vaccine how has the name Vaxzevria. Vaxzevrua is not available in the Yukon.

I have heard of some side effects affecting the heart, after people receive an mRNA vaccine. What is the risk of this?

There are rare cases of heart inflammation from COVID-19 mRNA vaccines. One type of inflammation is myocarditis (inflammation of the heart muscle). The other is pericarditis (inflammation of the lining outside the heart).

In most of these people, symp­toms began within a few days following their second dose of vaccine. The chance of having this occur is very low. Symptoms to watch for include:

  • chest pain;
  • shortness of breath; and,
  • feelings of having a fast-beating, fluttering, or pounding heart.

Most people experience mild illness. They respond well to treatment and rest with a full recovery.

It is more common to get myocarditis and pericarditis from a COVID-19 infection. The benefits of immunization far outweigh the potential risks of COVID-19 infection.

If you have symptoms within a week of getting a COVID-19 vaccine, seek medical care. Read more on heart inflammation and COVID-19 mRNA vaccines.

Do the COVID-19 vaccines affect fertility and menstrual cycles?

COVID-19 vaccines do not cause infertility. There is no current evidence that they impact menstrual cycles.

Some people have reported changes to their menstrual cycle following vaccination. However, it is important to know that many factors can impact menstrual cycles.

These factors include:

  • sleep;
  • stress;
  • infection;
  • diet; and
  • exercise.

Getting COVID-19 may impact the menstrual cycle. More than 35% of people noted changes to their cycle after a COVID-19 infection. While studies are taking place to understand these impacts, we know that other vaccines do not affect the menstrual cycle. Read more from the Society of Obstetricians and Gynecologists of Canada.

If you are pregnant or thinking of getting pregnant, vaccination is the best way to protect yourself and your baby. Those who are pregnant are at increased risk of experiencing a severe case of COVID-19. Often this results in serious outcomes, including preterm birth.
