Ontario to shorten COVID-19 vaccine dose interval starting with health-care workers

When asked about the time frame for administering second COVID-19 vaccine doses to Ontarians, associate chief medical officer of health Dr. Barbara Yaffe said Monday the province will eventually see shorter intervals between mRNA vaccine doses, particularly for frontline health-care workers and for people in certain high-risk groups. But, the doctor said she doesn’t see the interval becoming “really short” but it might become shorter than 16 weeks.
