Scientists at the University of Alabama at Birmingham say they aim to begin enrolling patients soon for a clinical trial of a COVID-19 vaccine.

Researchers at UAB’s Alabama Vaccine Research Clinic hope to get approval this week to start enrolling patients in a study to test the effectiveness of a COVID vaccine being manufactured by the pharmaceutical firm Johnson & Johnson, clinic director Dr. Paul Goepfert said.

The company is trying to recruit 60,000 participants for the study, Al.com reported.

The vaccine UAB plans to test requires only standard refrigeration, and can be given in a single dose, Goepfert said.
