Notably, there are two walk-in clinics, with no appointment required; Tuesday June 29, at the Julie McArthur Recreation Centre in Owen Sound from 4:30 to 6:30 pm; and again Wednesday, June 30, at the P&H Centre in Hanover from 4:30 to 6:30 pm. These clinics are for those 18 years an older and will offer Moderna vaccine, both first and second dose. Public Health notes the National Advisory Committee on Immunization (NACI) and provincial recommendations confirm Moderna is safely interchangeable with both Pfizer and AstraZeneca for second dose.
