COVID-19 vaccine – mRNA (age 6 months and older)

Learn about the COVID-19 mRNA vaccine, doses, side effects, and safety.

COVID-19 mRNA vaccine

COVID-19 mRNA vaccines help protect you against getting very sick from COVID-19 and needing care in the hospital.

The Moderna Spikevax KP.2 and Pfizer-BioNTech Comirnaty KP.2 vaccines are available in Alberta. They are updated mRNA vaccines that help protect you against the COVID-19 strains that are currently spreading.

Who should get this vaccine

Everyone is at risk of COVID-19.

COVID-19 vaccines are free and recommended for everyone age 6 months and older.

Immunization is strongly recommended if you are at higher risk of getting COVID-19 or getting very sick from COVID-19. This includes if:

  • You are age 65 years or older.
  • You live in a continuing care or supportive living facility.
  • You have a weak immune system.
  • You are an Indigenous person.
  • You are pregnant.
  • You are a member of a racialized and other equity-deserving community.
  • You are a person who provides essential community services, including healthcare workers.

Who should not get this vaccine

You may not be able to get an mRNA COVID-19 vaccine if:

  • You have an allergy to any part of the vaccine.
  • You had a severe (serious) or unusual side effect after this vaccine or one like it.
  • You are under age 6 months.

If you have allergies or have had a side effect from this vaccine, check with your doctor or a public health nurse before you get the vaccine.

Although you can get the vaccine if you have a mild illness such as a cold or fever, you should stay home until you are feeling better to prevent spreading your illness to others.

Check with your healthcare provider about when you can get an mRNA COVID-19 vaccine if:

  • You had COVID-19 in the past.
  • You are under age 18 years and have a history of multisystem inflammatory syndrome (MIS-C).

Be sure to talk to your doctor before you get an mRNA COVID-19 vaccine if:

  • You have a weak immune system (because of a medicine you take or a health problem).
  • You have had a stem cell or organ transplant.
  • You are getting CAR T-cell therapy (a type of cancer treatment).
  • You have a history of myocarditis or pericarditis within 6 weeks of getting a dose of COVID-19 vaccine.

Already had COVID-19

If you have already had COVID-19, it is not yet known how long your protection will last or how much protection you will have against variants. It is important to get a COVID-19 vaccine even if you have already had the virus.

The vaccine may give you better protection if you wait a while after having COVID-19 and then get a vaccine. How long to wait depends on your health history, the number of doses of COVID-19 vaccine you have had, and your risk of getting very sick from COVID-19.

If you have had COVID-19 in the past, check with your healthcare provider about when to get a COVID-19 vaccine.

Pregnancy and breastfeeding/
chestfeeding

While you are pregnant, you have a higher risk of getting very sick from COVID-19. Getting a COVID-19 vaccine lowers your risk of getting seriously ill from the virus.

You can get an mRNA COVID-19 vaccine if you are pregnant or breastfeeding/chestfeeding. There is more to learn about the Moderna KP.2 and Pfizer-BioNTech KP.2 vaccines while pregnant or breastfeeding/chestfeeding, but the information from the original mRNA vaccines found no concerns. Research shows that the mRNA vaccines are the safest type of COVID-19 vaccine to get while pregnant or breastfeeding/chestfeeding.

If you are pregnant or breastfeeding/chestfeeding and have questions about getting a COVID-19 vaccine, talk to your healthcare provider.

Vaccines

If you are age 6 months to 11 years, you can get the Moderna vaccine.

If you are age 12 years or older, you can get either the Moderna vaccine or the PfizerBioNTech vaccine.

Doses

Consent for immunization

A parent or guardian provides consent for a child under age 18 years to get a COVID-19 vaccine. If a parent or guardian cannot be at the appointment, they can use the consent form at COVID-19 consent for children under 18. In some cases, children under age 18 years may be able to give their own consent.

Alternate decision-makers (such as an agent, guardian, specific decision-maker, or co-decision-maker for another person) can use the consent form when they can't attend an immunization appointment with the person they represent. They must also provide documents that show they are the authorized decision-maker.

The person being immunized must bring the completed and signed consent form to their appointment.
