How did this happen?

The National Institutes of Health says the NIH has no record of this patient being given the drug.

┬áDr. Robert G. Pate, the NIH’s medical director for infectious diseases, told The New York Times the drug’s manufacturer, Pfizer, has not received a notification about the patient.

“The only information we have on this patient is from the manufacturer,” he said.

We have no record at all of this being administered to this patient,” Pate said.

Pfizer has not responded to CNN’s request for comment.
