ALERT: Lambton Public Health has been notified by the province that future orders of the Pfizer COVID-19 vaccine are temporarily delayed, so our remaining Pfizer supply needs to be prioritized.

Beginning Tuesday, December 21, in stock vaccines will be distributed as follows:

  • Residents aged 12-29 years old will receive the Pfizer vaccine as recommended by the National Advisory Committee on Immunization (while supplies last).

Moderna and Pfizer mRNA vaccines are interchangeable for people aged 30 and older, there is no need to cancel or change your appointment if you have already had one or two doses of Pfizer. Due to the Omicron variant, it is important to get a booster shot as soon as you can.
