What happened to Brianne Dressen after participating in the AstraZeneca COVID-19 vaccine trial, and how did the trial organizers respond to her adverse reactions?

Brianne Dressen experienced severe adverse reactions within hours of receiving the AstraZeneca vaccine during a Phase 3 trial. Her symptoms began with tingling in her injection arm on the way home, followed by blurred and double vision, distorted hearing, and eventually a slumped left leg that caused her to walk into doorways. Despite the trial contract promising medical and financial support for research-related injuries, Dressen received no response when she called to report her symptoms the morning after the injection. As a preschool teacher during COVID-19, she prioritized her students' need for stability and continued working despite her debilitating symptoms. Her experience highlights critical gaps in vaccine trial participant support systems and raises important questions about accountability and transparency in clinical research, ultimately leading her to co-found React19.org to advocate for other vaccine-injured individuals.
