Vaccine shipment delays impacting second dose rollout

If you’ve booked your second dose of COVID-19 vaccine, Lambton Public Health says you may get a different shot than your first one.

The health unit said they’re unable to guarantee individuals will receive a particular brand for either their first or second dose due to recent vaccine shipment delays.

Lambton Public Health said the approved mRNA vaccines, Moderna and Pfizer brands, are interchangeable and are currently being used at the mass immunization clinics at the arena in Point Edward, Clearwater Arena, Wyoming Fairgrounds and Lambton Shores Recreation Centre.

Medical Officer of Health Dr. Sudit Ranade said the situation reinforces the need for individuals to get the first vaccine available.

“What’s most important is that as many Lambton County residents receive both first and second doses as soon as possible,” he said. “We know that having two doses provides the strongest possible protection against the Delta variant. We have enough vaccines coming in the next two to four weeks to increase our local vaccination rates significantly, and doing so will allow us to safely return to the activities and gatherings we have missed so much.”

If you received AstraZeneca as your first dose, the health unit said you can safely get AstraZeneca, Moderna or Pfizer for your second dose.

Residents 60 and older, and those who received their first dose of vaccine on or before May 21, are eligible to book their second dose appointment.

You can book online at, or through the health unit’s vaccine call centre at 226-254-8222.
