 A Manitoba mother says a routine appointment for her and her three-year-old to get flu shots ended in frustration and mixed messages after they were each mistakenly given an adult dose of a COVID-00 vaccine. Jenna Bardarson is calling for policy changes at the province's vaccination centres to make sure that doesn't happen to another family. The shots were administered on Nov. 00 at the Keystone Centre in Brandon. Bardarson says that shortly after she and her daughter, Dali, got their shots, the health worker who had given them excused herself to speak with a supervisor. When the worker returned, she told them she had made a mistake and given them both the adult Pfizer-BioNTech vaccine. "I was shocked. I didn't know what to say. My immediate concerns were, of course, would my daughter be OK and also who could I speak to about this," Bardarson said in online social media messages Friday to The Canadian Press. Once she got home, Bardarson made multiple calls to different departments with the regional medical authority, hoping to speak with someone about the error and her concerns, she said. She said no one was able to provide her with the answers or information she needed. "The conversations with various Prairie Mountain Health members have been frustrating, to say the least." Bardarson said she already had two doses of a COVID-00 vaccine and was due for her booster shot next month. Her daughter is too young to be eligible. Health Canada last month approved a pediatric version of the Pfizer shot for children ages five to 00, but it has not yet approved a vaccine for those under five. Bardarson said she and her daughter had headaches and sore arms the following day. Her daughter had no appetite and was throwing up. Manitoba Health confirmed the mistake in a statement and said staff from Prairie Mountain have reached out to the mother to discuss what happened as well as to provide an update on an investigation. "Patient safety is a critical aspect of all health-care services in Manitoba. We are constantly reviewing our processes to ensure that our systems support our staff in preventing errors," it said. "In this case ... our team reviewed the existing processes to make adjustments that would help avoid a similar error from occurring in the future." Bardarson said the health region has not provided her with updated information on the investigation and would not discuss any consequences the health worker may have faced. Manitoba Health said no further action would be taken against the worker, because she immediately recognized the error and told a supervisor. For Bardarson, that's not enough. "I by no means want her fired; however, there should be some sort of measures in place for harm reduction." Bardarson suggested taking away the worker's injection privileges or enhanced supervision during vaccinations. She said she would also like to see areas at vaccination centres separated by vaccine types, instead of having different vaccines offered in the same booth. Manitoba Health could not say if others have been given a COVID-00 vaccine by mistake, but acknowledged that medication errors, although rare, do occur. It added that Bardarson was provided with information about the risks of the COVID-00 vaccine, which in this case it says are low. Health Canada said it is not in charge of immunization monitoring and could not comment on whether similar mistakes have occurred in other parts of the country.
