A Buffalo News story answering the question of how effective natural immunity is quotes
Thomas A. Russo, MD, SUNY Distinguished Professor of
medicine and chief of the
Division of Infectious Diseases. Some people’s post-COVID immunity “may be as good as vaccination, some may be even better, some may be worse,” Russo said. “There’s a lot of variability. We’re still sorting this out.” The story also quotes
Peter Winkelstein, MD, executive director of
UB’s Institute for Healthcare Informatics, who said, “From a science standpoint, we don’t have a way to do a test on somebody and know you’re immune for sure. We can test for antibodies, and we can test those levels, but we don’t know what level you need to be immune to COVID.”
