He further clarified the side effect that occurred and what resulted in the patient going to the hospital as being short of breath. Caller explained when she went to the hospital they said she had fluid around the heart.

She is on other medications, but he stated he is not able to spell out/provide all those details we are asking for at this time. When probed for details mentioned the heart doctor who performed the procedure and drained fluid off heart was a specialist. The thing that he was thinking about that brought this to his condition that has been lingering on his mind over the weekend is what he read. He asked them what caused this to happen, it's not often fluid fills outside the heart, but they did not know.    The lot number for the vaccine, [BNT162B2], was not provided and
