Lambton Public Health Issues Update re: COVID-19 Vaccine Second Dose Appointments

Point Edward, ON – On March 10, COVID-19 vaccination intervals were extended from four weeks to 16 weeks for three vaccines (Moderna, Pfizer & AstraZeneca) based on a decision by the Ontario Government, following recommendations from the National Committee on Immunization (NACI).

This means if a resident’s second dose appointment was scheduled four weeks after their first dose (or if the resident did not receive an additional appointment), their second dose booking needs to be re-scheduled. The new appointment will be 16 weeks after the resident’s first dose. Second dose appointments for these groups are expected to rollout starting in June 2021.

“If your printed receipt from a first dose clinic indicated a suggested second dose date (i.e. in April), these dates are no longer valid based on the Government’s new 16 week interval,” said Dr. Sudit Ranade, Medical Officer of Health for Lambton County.

Lambton Public Health will contact you directly with an appointment booking option. Please do not call or request your second dose appointment at this time. The health unit is in the process of securing appointment options for this group under a new set of dates. Please do not attend a clinic expecting to receive your vaccination unless you have an appointment booked.

“LPH is working through some challenges with the Provincial online system which currently does not allow the booking of a single appointment,” said Dr. Ranade.  “It is important for the public to be patient until we have a system in place to book second doses. We will communicate the options as they become available.”

Note: If you booked your COVID-19 vaccination appointment using the Provincial Booking System, your first and second dose appointments were scheduled using the new 16 week interval. Your appointment is still confirmed, and no further action is required.
