Ontarians 18+ eligible for Bivalent booster on September 26 – new paediatric Pfizer vaccine also available

Effective September 26, all adults aged 18 and over are eligible to receive the bivalent booster dose which may offer more targeted protection against the Omicron variants. Appointments can be booked through the COVID-19 vaccination portal or by calling the Provincial Vaccine Contact Centre (PVCC) at 1-833-943-3900. Eligible individuals can also book an appointment directly through public health units that use their own booking systems, Indigenous-led vaccination clinics, participating health care providers and participating pharmacies.

Individuals who are eligible to receive a bivalent booster can do so at a recommended interval of six months (168 days) from their previous dose, or a minimum interval of three months (84 days), regardless of how many booster doses they have already received. Individuals who would like to receive their bivalent booster between three months and the recommended six-month interval, or who otherwise have difficulty booking their appointment online, must call the PVCC to book an appointment.

“With the start of the fall and winter respiratory illness season, it is especially important to make sure people stay up to date with their vaccines,” said Sylvia Jones, Deputy Premier and Minister of Health. “COVID-19 vaccinations and boosters are the best tool to keep people healthy and out of hospitals, and to ensure Ontario’s economy stays open as the weather cools and people spend more time indoors.”

Also, as of September 26, 2022, the new paediatric Pfizer vaccine will be another vaccine available for children aged between six months to under five years old, including those who are immunocompromised. The vaccine is a three-dose primary series, with a recommended dosing interval of eight weeks between doses. Mixing products for your infant or child’s primary series doses is not recommended. Your child should receive the same product for all their primary series doses, whether it is Pfizer or Moderna. Parents and caregivers can continue to book appointments through the same methods as for the bivalent vaccination.

“The bivalent COVID-19 booster provides better protection against the currently circulating COVID-19 variants in Ontario,” said Dr. Kieran Moore, Chief Medical Officer of Health. “We also know that getting your child vaccinated improves their immune response to COVID-19 infection and reduces the possibility of severe disease and hospitalization and post COVID-19 symptoms.”

COVID-19 vaccines, along with continued access to testing and antivirals and updated public health guidance, give Ontarians the tools they need to make the best decisions for themselves on how to stay safe, healthy and out of hospitals as the province continues its efforts to support the recovery and rebuilding of the health system.
