What was the government and institutional response when COVID vaccine trial participants reported severe adverse effects from the AstraZeneca vaccine?

When Brianne Dressen and another participant reported identical severe neurological injuries from the AstraZeneca vaccine trial, the NIH responded within 24 hours to their reports. Despite acknowledging these injuries, government messaging continued to promote vaccine safety, telling people to "go get your shot" while claiming they were just working on FDA paperwork. Ten days after the reports, two significant actions occurred: AstraZeneca was pulled from consideration in the United States, and the National Institutes of Health initiated a formal study to investigate neurological complications following COVID vaccines in general. This response highlighted the disconnect between official safety messaging and the serious adverse events being documented by trial participants.
