Vaccine maker Moderna said Friday it has increased the number of minority volunteers involved in its Phase 3 clinical trial of a Covid-19 vaccine over the past week.
The company reported Friday that enrollment in the trial has risen to 23,497 participants, up from 21,411 a week ago.
The current breakdown in numbers include 59% White participants, 22% Hispanic, 11% Black, 5% Asian and 3% other populations.
Last week the trial included 68% White volunteers, 20% Hispanic, 7% Black, 3% Asian and 1% other populations.
Moderna said last week it was increasing its efforts to reach more diverse populations, even if it impacted the speed of enrollment.
"We believe these efforts will improve the quality of the study and confidence in the vaccine by building evidence for benefit in the communities at highest risk of COVID-19," a Moderna spokesperson said last week in a statement to CNN.
The trial has been struggling to enroll enough minorities since at least mid-August.
