NATIONAL - Within the next year, medical experts expect a coronavirus vaccine to be released to the public.

About 30,000 people will be involved in the phase 3 study across the country.

According to Mark Mckenzie, Regional Medical Director at Wake Research in Raleigh, half of the participants will get a placebo and half will get the vaccine. 

"[The] Phase 1 trial is an investigational trial that is given to people who are normal. We manage and watch them closely and sometimes overnight, and several nights. Phase 2 is broader. We use the product in people who have risk or a condition we're concerned about."

Patients will be monitored for the next two years. Both Mckenzie and Duke Physicians Scientist Tony Moody say these trials are for the public's safety.

"None of the steps are being skipped. We're just moving more quickly, going from Phase 1 to Phase 2 to Phase 3. All the delays that typically occur are being cut out," Moody said.

Moody does expect side effects on a small part of the population, but also says that's not uncommon.

"We know everything has side effects. Just because a vaccine has reported side effects, or there's something rare, doesn’t mean that it's unsafe. What it means is when you start doing things in very large numbers of people, you see rare things," he said.

Both medical experts agree you should take the vaccine if it passes Phase 3. Their concern is whether or not you'll be able to take it when it's released to the public.

"It won't be a lack of desire. Just to go from making enough vaccine to make enough for 30,000 to 300 million or 7 billion, thats a big problem. It's a lot to ask for vaccine manufactures to get that up that quickly," Moody said.
