Ontario’s COVID-19 vaccine program has transitioned to an annual program which aligns with the National Advisory Committee on Immunization (NACI) recommendations where individuals receive an updated COVID-19 vaccine annually. An annual updated COVID-19 vaccine will boost the immune response and provide an updated vaccine to protect against circulating strain.
The COVID-19 vaccine is available free of charge to all individuals 6 months of age and older in Ontario at no cost, even if you do not have an Ontario health card.
