“Is this a more generalized inflammatory response from the vaccine that’s localizing in the heart in some patients?” Gottlieb requested, rhetorically. “Or is this something that’s more direct, where the vaccine itself is triggering some kind of very targeted immune reaction and it’s manifesting in this way? We don’t have the answers to these questions.”
It’s doable further instances have not been recorded, Gottlieb mentioned, however “we are probably capturing most of the severe cases.” He added, “When you look at the number of people who are having severe cases of pericarditis, it’s very small numbers right now.”
