Use the COVID-19 Immunization Schedule to determine if you are eligible for a third, fourth, or fifth booster dose.
Third Dose for Residents Age 12-17
Residents ages 12-17 are eligible for a third dose of the COVID-19 vaccine. The third dose can be received at least 6 months after a second dose of the COVID-19 vaccine was received.
Review some commonly asked questions about the 12-17 third dose:
- Why are they recommending a third dose of the COVID-19 vaccine for the 12-17 age range?
- With the Omicron variant, current evidence suggests that 2 doses of the COVID-19 vaccine are no longer adequate to protect against symptomatic infection from the COVID-19 virus. Research shows that among all age ranges 12+, the effectiveness of the vaccine wanes over time. Data is also showing that youth ages 12-17 are experiencing high rates of infection due to the omicron variant.
- To increase protection against COVID-19, support the health of those ages 12-17 and reduce transmission of the omicron variant, the National Advisory Committee on Immunization (NACI) is recommending that residents ages 12-17 receive a third dose at least 6 months after their second dose was received.
- Why would a 12-17 year old need a third dose?
- Current evidence shows that 2 doses of the COVID-19 vaccine are not sufficient at preventing infection from the omicron variant. In the adult population, third doses are more effective at preventing infection and more effective at preventing severe illness due to the COVID-19 virus.
- Preventing a COVID-19 infection will prevent illness, prevent sick days, and reduce the risk of transmission to loved ones who may be vulnerable and at an increased risk of complications related to a COVID-19 infection.
- Should I be concerned about the risk of myocarditis following a third dose?
- It is important to remember that the occurrence of myocarditis or pericarditis following immunization is still very rare. At this time, no safety concerns have been identified in the 12-17 age group following the administration of a COVID-19 third dose. In adults (ages 18+), the frequency of adverse events following immunization with a third dose is comparable or lower than those experienced after the second dose.
- It is important to remember that residents in this age category are offered the Pfizer COVID-19 mRNA vaccine as it has fewer occurrences of myocarditis or pericarditis following immunization in those 29 and younger than the Moderna COVID-19 mRNA vaccine does.
Third Dose for Residents Age 18+
All residents 18 years of age or older are eligible for a third dose of the COVID-19 vaccine. The third dose can be received at least 3 months after a second dose was administered.
Review some commonly asked questions about the COVID-19 third dose for adults:
- Should I be concerned about the risk of myocarditis or pericarditis?
- Learn more about the occurrence of myocarditis and pericarditis follow immunization.
- Which vaccines are available?
- Peterborough Public Health is administering Moderna and Pfizer COVID-19 vaccines at their clinics.
- As of December 3, 2021, the Pfizer COVID-19 is recommended for residents 29 and younger. Reports of myocarditis or pericarditis following immunization are more often seen in those 29 and younger. Evidence suggests that it is more common to occur after receiving the Moderna COVID-19 vaccine compared to the Pfizer COVID-19. This is why there is a preferential recommendation for those 29 and under to receive the Pfizer COVID-19 vaccine.
- The Moderna COVID-19 vaccine is recommended for residents 30 and older. Ongoing research suggests that Moderna has less waning immunity over time and maintains higher efficacy compared to the Pfizer COVID-19 vaccine. This means the vaccines benefits last longer and may provide stronger protection than the Pfizer COVID-19 vaccine.
- Why do we need a third dose?
- A third dose in needed to prevent an infection and severe outcomes due to a COVID-19 infection.
- Recent data shows that 3 doses of the COVID-19 vaccine are more effective at preventing a COVID-19 infection and complication related to an infection. Data is emerging that 2 doses of the COVID-19 vaccine show waning immunity across all age ranges. This is further supported by evidence that suggests two doses for the COVID-19 vaccine are less effective against the omicron variant than previous variants of concern.
- Research suggests that a third dose can provide additional protection against symptomatic infection from the omicron variant. A booster dose is also very effective at preventing severe infection or hospitalization.

The safety of vaccines is carefully monitored, starting early in the product development and continuing for as long as the vaccine is being used. Health Canada’s independent drug authorization process is recognized around the world for its high standards and rigorous review. Decisions are based only on scientific and medical evidence showing that vaccines are safe and effective. The benefits must also outweigh any risks. For more information see Health Canada Vaccines and treatments for COVID-19.
As with all vaccines, the possibility of a serious side effect is very rare. These are typically due to an allergic reaction or other health conditions that you may have prior to receiving the vaccine. Speak to your healthcare provider if you have any concerns before receiving the vaccine. Any serious side effects or adverse events following immunization (AEFI) related to the COVID-19 vaccine are reported to a primary care physician and investigated by the local public health unit. All AEFI in Canada that are related to the COVID-19 vaccine can be found here.

Health Canada has launched a vaccine injury support program. Learn more about this program.
In Canada, there have been reports of some people experiencing myocarditis or pericarditis after receiving the COVID-19 vaccine. These reports have most often been in males 29 and younger within one week of receiving the COVID-19 vaccine. These reports have been very rare and most have experienced mild symptoms and made quick recoveries.
Data shows that this occurrence is more common in young people after receiving the Moderna COVID-19 vaccine compared to the Pfizer COVID-19 vaccine. Out of an abundance of caution, on September 29, 2021, the province of Ontario provided recommendation for the use of the Moderna COVID-19 vaccine to be limited to those 30 and older.
The benefits of the COVID-19 vaccine continue to outweigh any potential risks. Vaccination with the COVID-19 vaccine is highly recommended for all eligible residents.
If you have questions about the COVID-19 vaccine and your personal health, speak with your health care provider or connect with a health care provider or registered nurse virtually.
