For the second time this year, Alberta Health Services has notified patients about a potentially ineffective vaccine.

The health authority said the dTap vaccine that was provided to 298 patients at the Leduc Community Hospital’s emergency department may have been ineffective because of incomplete monitoring of a vaccine fridge.

The dTap vaccine prevents against diphtheria, tetanus and pertusis. The vaccine was being used to update immunizations for people with possible tetanus-prone wounds.

AHS said the risk of tetanus infection is “very low,” but it’s advising patients to get re-immuized.
