COVID-19 Vaccines
COVID-19 vaccination, remains the most effective intervention for preventing severe outcomes of COVID-19, including hospitalization and death. Receiving an updated COVID-19 vaccine provides protection against currently circulating SARS-CoV-2 variants.
In Ontario, COVID-19 vaccines are recommended in accordance with guidance from the Ministry of Health for unvaccinated and previously vaccinated individuals 6 months of age and older, particularly for those at increased risk of SARS-CoV-2 infection or severe illness due to COVID-19.
PHO works closely with the Ministry of Health, local public health units and other health system partners to provide scientific expertise, data and resources for Ontario’s COVID-19 vaccination program.
