Should youth get a COVID-19 vaccine as soon as it's available to them?

Transcript

A super appears on a pink background: COVID-19 vaccine questions

A person and their child are seated in their home. The person speaks directly to the camera: Should youth get the COVID-19 vaccine as soon as it’s available to them?

Cut to a doctor in an office, the window behind her shows a person in a full-body protection suit working in a lab; then a super appears:

  • Dr. Alyson Kelvin
  • Virologist and Assistant Professor
  • Department of Pediatrics, Dalhousie University and the IWK Children’s Hospital, Nova Scotia

The doctor responds to the person’s question.

Dr. Alyson Kelvin: Before being approved for use in youth in Canada, vaccines are carefully assessed by Health Canada to determine their safety, quality, and how well they work. Clinical trial data indicates that COVID-19 vaccines are very effective at preventing disease in youth. Vaccination can also help youth get back to what they love and need for their mental health and well-being.

Pop-up speech boxes appear with the following questions:

  • How effective are COVID-19 vaccines for youth?
  • How do I know a COVID-19 vaccine is safe for my youth without long-term data?
  • Will youth get the same dose of COVID-19 vaccine as adults?

A super appears on a pink background: COVID-19 vaccine questions

A person speaks directly to the camera to ask a question: I’m young and I’m healthy, why do I need to get the vaccine if I’m not at risk?

Cut to a surgeon in an operating room, then a super appears:

  • Dr. Kal Belay
  • Acute Care and Minimally Invasive General Surgeon
  • William Osler Health System

The doctor responds to the person’s question.

Dr. Kal Belay: COVID-19 can have life-threatening complications and there’s no way to tell how it will affect you. The vaccination is an important tool to help stop this pandemic and help us get back to normal life.

Do I need to get the vaccine if I've already had and recovered from COVID-19?

Transcript

A super appears on a pink background: COVID-19 vaccine questions

A person seated on a chair speaks directly to the camera to ask a question: Do I need to get the vaccine if I've already had and recovered from COVID-19?

Cut to a doctor in a library, then a super appears:

  • Dr. Marc-André Langlois
  • Executive Director, Coronavirus Variants Rapid Response Network (CoVaRR-Net)
  • Professor, Faculty of Medicine, University of Ottawa

The doctor responds to the person’s question.

Dr. Marc-André Langlois: Yes, absolutely. If you’ve previously had a COVID-19 infection you can receive both COVID-19 vaccine doses. It’s not clear how long protection lasts after an infection, and the risk of re-infection with a variant is not clear at this time. Vaccination remains one of the most effective ways to protect our families, communities and ourselves against COVID-19 and its variants. Vaccines, in combination with public health and individual measures, will reduce the spread of COVID-19.

How long does it take for a COVID-19 vaccine to work after I've received it?

Transcript

A super appears on a pink background: COVID-19 vaccine questions

A person seated in a living room speaks directly to the camera to ask a question: How long does it take for a vaccine to work after I’ve received it?

Cut to a doctor in a library, then a super appears:

  • Dr. Marc-André Langlois
  • Executive Director, Coronavirus Variants Rapid Response Network (CoVaRR-Net)
  • Professor, Faculty of Medicine, University of Ottawa

The doctor responds to the person’s question.

Dr. Marc-André Langlois: Regardless of which vaccine you get, the first dose provides good protection from getting the virus and excellent protection from severe disease. Protection starts to build within a few days and peaks at about 3 weeks after receiving that dose of the vaccine.

It is important to get the second dose as this further boosts the immune response and is essential for longer lasting protection and better protection against the variants.

Will the COVID-19 vaccines protect me against new variants?

Transcript

A super appears on a pink background: COVID-19 vaccine questions

A person sitting in a living room speaks directly to the camera to ask a question: Will the COVID-19 vaccines protect me against new variants?

Cut to a doctor in an exam room, then a super appears:

  • Dr. Kumanan Wilson
  • Internal Medicine Physician
  • The Ottawa Hospital

The doctor responds to the person’s question.

Dr. Kumanan Wilson: Our understanding of COVID-19 variants is changing all the time. Research is ongoing to determine if new variants affect how effective the authorized vaccines are at preventing infection and disease.

Even if a COVID-19 vaccine isn’t as effective against a variant, people who have received two doses will have better protection against both getting the virus and getting sick from the virus. That’s why it’s so important to get your second dose.

The vaccine also protects against variants in another way. The more a virus spreads to people, the greater chance it may mutate and potentially become a variant. The more people who are vaccinated, the better to help slow the spread and reduce the chance of new variants.

Do I need to get the second dose?

Transcript

A super appears on a pink background: COVID-19 vaccine questions

A person speaks directly to the camera to ask a question: Do I need to get the second dose?

Cut to a doctor in an operating room; a super appears:

  • Dr. Stanley Vollant
  • General Surgeon
  • Notre-Dame Hospital, Montréal

The doctor responds to the person's question.

Dr. Stanley Vollant: The first dose of COVID-19 vaccine offers you some protection, but not as much as you get from two doses. The second dose of the vaccine gives you a better, stronger and a longer protection from it. You want your immune system to produce very strong and high level of antibodies so that your body can fight it. But, you have to take both doses.
