As a doctor of nursing practice, Tara Cavazos is very comfortable being the one giving the shots. But last month, she found herself in the role of “patient” as a participant in Pfizer’s COVID-19 vaccine trial in Dallas.
In the trial, participants don’t know whether they’ve received the vaccine or a placebo—a hypertonic saline solution. Cavazos reported feeling “some discomfort” during her first injection, along with residual pain in her bicep.
“It felt different than a typical flu shot or a tetanus vaccine,” she said.
