As scores of researchers across the world scramble to develop vaccines for the novel coronavirus, a World Health Organization envoy is cautioning that one may never appear at all, according to a new report.

Dr. David Nabarro, who also serves as a professor of global health at Imperial College London, raised the possibility in a new interview with CNN.

“There are some viruses that we still do not have vaccines against,” Nabarro told the outlet. “We can’t make an absolute assumption that a vaccine will appear at all, or if it does appear, whether it will pass all the tests of efficacy and safety.”

In that case, according to the report, treatments may be developed, but the world could still see yearly coronavirus outbreaks — with deaths — and lockdowns will need to be periodically strengthened and loosened.
