Over 200 People In Niagara Have To Get A Repeat COVID-19 Vaccine Dose After Saline Mix Up

Some individuals will receive a third dose.

Creator

Niagara Region Public Health has asked 205 people to receive another dose of a COVID-19 vaccine after six people were accidentally injected with a saline diluent.

In a statement, Niagara Region Public Health revealed that on June 16, six people were injected with a saline diluent instead of a COVID-19 vaccine dose at the Niagara Region Public Health clinic in Port Colborne. The saline diluent is a harmless substance that is mixed with the Pfizer vaccine concentrate before administration, NRPH explained.

This means six people may have believed they were fully vaccinated when they didn't actually receive a vaccine dose.

Public Health is currently contacting 205 people who received a dose at the Port Colborne clinic that day to book another vaccine appointment, according to the statement.

Niagara Region Public Health has acknowledged that some people will be receiving a third dose. However, they clarified that "receiving a third dose of vaccine is safe, though it does not provide significant benefit."

Niagara Region Public Health said they "deeply regret this error" and that "immediate corrective measures have been taken."
