Chief Medical Officer of Health Extends Time Interval for Second Dose of COVID-19 Vaccine

Kingston – To increase the number of individuals benefitting from a first dose of COVID-19 vaccine in the context of a limited COVID-19 vaccine supply and the presence of highly transmissible variants of concern, Dr. David Williams, Ontario’s Chief Medical Officer of Health has extended the time interval of the second dose of COVID-19 vaccines up to 16 weeks.

Over the next few weeks, many clients who received their first dose on or before March 10 will receive an email with a booking cancellation notification and a follow-up phone call from KFL&A Public Health to (re)schedule their second dose appointment for a later date in accordance with these new guidelines.

Please DO NOT contact KFL&A Public Health to inquire about (re)scheduling the second dose appointment. KFL&A Public Health will contact all individuals impacted by this change starting with those who are scheduled for their second dose next week.

We know everyone is eager to receive their second dose, but please be assured that there is measurable immunity detectable by 12 days following the first dose of the COVID-19 vaccine. These new guidelines will allow for more individuals to benefit from a first dose of COVID-19 vaccine and to help prevent severe complications from the COVID-19 virus.

KFL&A Public Health must adhere to these recommendations that come from the direction of the Ministry of Health.
