The fourth dose of the COVID-19 vaccine is now available for long-term care residents and other senior citizens, the Ontario government said on Thursday.

Ontarians living in congregated settings like long-term care homes and retirement homes can get the fourth dose of the mRNA vaccine if three months have passed since they received their third dose.
