N4T Investigators: Vaccine Fail? – UPDATE

TUCSON – We have a News 4 Tucson Investigators follow-up on a story we first brought you back in January.

It involves a potential issue with vaccines that may have impacted as many as one-thousand patients, including children, at a north side Tucson clinic.

“They’re supposed to help you, you know, raise healthy kids, and take care of your kids, but when something like this happens it’s just like kind of like a slap in the face,” Erica Baca told the News 4 Tucson Investigators.

Baca first learned about a potential problem with her ten-month-old daughter’s vaccination when she went to see her pediatrician last fall.

“As a parent, like I’m thinking I’m doing the right thing for my kids, and you know, I just lost all the confidence I had in my healthcare provider,” Baca told the News 4 Tucson Investigators.

Baca, who is a mother of three, tells the News 4 Tucson Investigators the problem with her daughters two, four, and six-month vaccinations actually dated back to last March.

As the News 4 Tucson Investigators learned, a refrigerator issue at the Banner – UMC North Hills Clinic on W. Ina Road was discovered last October.

According to Banner University Medical Group, some vaccines may have been temporarily stored at temperatures outside the required range.

Baca tells the News 4 Tucson Investigators, Banner has done little to ease her concerns as a mother.

“There’s like, just lack of care. No concern. It’s kind of like, OK it’s fine, revaccinate your kids, and it’s all good. But, really is it? I don’t know,” Baca said.

According to a letter from Banner University Medical Group, they said they could not guarantee the vaccines they administered are fully effective.

The News 4 Tucson Investigators wanted to know how could something like this happen, and what is Banner doing to make sure it does not happen again.

In a statement to the News 4 Tucson Investigators, a Banner Health spokesperson told us:

“Banner Health regularly monitors and reviews vaccine storage units throughout the system. If a storage unit ever fails to meet temperature control standards, it is fixed or replaced, and potentially impacted individuals are offered complimentary revaccination. It is important to note that there are no additional medical risks associated with revaccination. We encourage patients to seek out their primary care physicians if they have any questions or concerns whatsoever.”
