(NewsNation) — A Utah mother is suing AstraZeneca after participating in a clinical trial during the company’s COVID-19 vaccine development.

Brianne Dressen told NewsNation host Chris Cuomo that she’s suffering from an “invisible illness.”

“The reality is I am in pain every second of every day,” Dressen said Tuesday night on “CUOMO.” “Unfortunately I have a severe progressive neuropathy that will continue to progress until my life is done. It’s a very sharp, tingling, electrical sensation. … I’m completely dependent on other people.”

Dressen said she’s no longer able to care for her children in the way that she used to, before volunteering to get the vaccine.

“Everything revolves around mom. My children have to figure out if I can help them that day with their homework. If I can make them breakfast, get out of bed. ‘Is mom gonna be able to take them to school?’ These are very simple tasks that people take for granted,” Dressen said.

Dressen said that when she reported her symptoms to AstraZeneca, she was met with “silence.”

“I thought that they were going to be able to help me. In my contract, they stated that they would be there to help me. … It’s as if they couldn’t get away from me fast enough. I’m nothing more than a number to them,” Dressen added.

NewsNation has reached out to AstraZeneca for comment on the lawsuit.
