As of 9:30 a.m. today, June 9, individuals who received their first mRNA (Pfizer or Moderna) COVID-19 vaccine dose on or before April 18 will be eligible to book their second dose vaccine appointment at a mass vaccination clinic, local pharmacy, or healthcare provider office that is administering vaccines.

Appointments are still required for first and second COVID-19 vaccine doses at all of the mass vaccination clinics, participating pharmacies, and participating healthcare providers. No walk-ins will be permitted. When attending your booked appointment, please bring your health card or other identification document such as a driver’s license or passport.

Those eligible to book an appointment do not need to receive the second vaccine in the same location as the first. We encourage all eligible community members who want to attend a mass vaccination clinic to book online through the online booking system or by calling the vaccination booking call centre at 226-773-2200 to make an appointment. Due to expected call volumes initially, it may take multiple attempts to speak with a Windsor-Essex County Health Unit representative.

The Windsor-Essex County Health Unit also continues to provide a COVID-19 Vaccine Waitlist through the online booking system. Waitlist registration is for anyone who received an mRNA vaccine in the month of April. The waitlist is used across all targeted vaccination clinics and you will only be contacted if a time slot becomes available the day that you select. Selecting a time slot does not mean that you have an appointment. Please do not go to a clinic unless you are called and approved for an appointment. 

Despite the vaccine rollout, please continue to practice public health measures to help prevent the spread of COVID-19 in our community:

  • Maintain a 2 metre distance from others.
  • Limit your contacts to your household only.
  • Wash your hands with soap and water thoroughly and often.
  • Avoid touching your eyes, nose, and mouth with unwashed hands.
  • Use a medical or non-medical mask (e.g., cloth) in public settings.
  • Cover mouth & nose with a tissue or use the inside of your elbow when you cough or sneeze.
  • Stay home and do not go to work or school if you are sick.
