Dr. Michael Osterholm, director of the University of Minnesota's Center for Infectious Disease Research and Policy, told 5 EYEWITNESS NEWS "long-term immunity to COVID-19 is hard to know" for those who've contracted the disease and are now recovering.

"There are surely data that would support that the immunity may only be short-term, meaning months, not years and years," Osterholm said. "This could be problematic because it may mean we have to keep revaccinating people if we get a successful vaccine."

Osterholm said he is working with a team of 20 of the world's top researchers and scientists to learn more about exactly how COVID-19 is transmitted and who might be what's called a "super spreader" in the population.
