Public health officials in Ottawa are ramping up a vaccination program to limit the spread of the mpox virus, and there are signs that early uptake has been brisk.

After announcing on Saturday that it was opening 36 spots for vaccination against the virus that causes the infectious disease formerly known as monkeypox, Centretown health clinic MAX Ottawa said Monday it’s fully booked and exploring ways to expand the program.

Ottawa Public Health’s (OPH) Sexual Health Clinic on Clarence Street is also offering vaccination against mpox. Eligibility criteria can be found on the OPH website.
