Health officials say more than 30,000 people have volunteered to participate in two COVID-19 vaccine trials.
Paul Mango, deputy chief of staff for policy at the U.S. Department of Health and Human Services, told Today, “We feel we’re absolutely on track, if not a little bit ahead” of the goal of developing a safe COVID-19 vaccine.
The two manufacturers, Moderna and Pfizer, hope to enroll 60,000 volunteers for the phase 3 trials. Mango explained how enrollment is halfway complete but did not share how many people are in each attempt.
In partnership with the U.K.’s University of Oxford, AstraZeneca has also started phase 3 trials on its vaccine.
Still, “there are no guarantees in science,” Mango said. It is possible that the vaccines will not be sufficient.
While a coronavirus vaccine is widely seen as a silver bullet to resolve the ongoing pandemic, many Americans say when a vaccine is available, they will not be first in line to get it.
A national poll found that as many as 50% of Americans may wait to get the vaccine. About 70% said they had concerns about safety as the coronavirus vaccine could be one of the fastest ever to be developed.
