The US National Institutes of Health is still looking for volunteers to participate in vaccine trials, Director Dr. Francis Collins said in an interview Wednesday with CNN’s Wolf Blitzer.
“We still do need people to take part in these trials,” Collins said.
Even though two vaccines are close to receiving emergency use authorization from the US Food and Drug Administration, four more are still in the works, he said.
"And the more we have the better, because the sooner we can get those out to people," Collins said.
Collins said the NIH is counting on volunteers, whom he called “heroes,” to participate in the trials.
“So we just put up today a new way for people who are interested in both therapeutic trials, because we're looking for ways to treat the disease, so this would be for people who tested positive, but also people who are looking to serve in vaccine trials,” Collins said.
Collins said the NIH is also still looking for people to donate convalescent plasma. “We’re still interested in that,” he said.
