A person in California who received a CCP virus vaccine on Jan. 21 died several hours later, authorities said.
The cause of death isn't yet clear.
"The vaccine was not administered by Placer County Public Health. There are multiple local, state, and federal agencies actively investigating this case; any reports surrounding the cause of death are premature pending the outcome of the investigation," the Placer County Sheriff's Office said in a statement.
Authorities didn't disclose identifying characteristics of the individual or say whether the vaccine was produced by Moderna or Pfizer.
Authorities do not have a centralized location of verified deaths of people who have been vaccinated. “Any reports of death following the administration of vaccines are promptly and rigorously investigated jointly" by the administration and the Centers for Disease Control and Prevention, the spokeswoman added. The agencies didn't respond to requests for comment about the California death.
The reason was a “higher-than-usual number of possible allergic reactions,” California State Epidemiologist Dr. Erica Pan said in a statement.
The CCP virus vaccine doses were produced by Moderna.
Moderna, the Centers for Disease Control and Prevention, and the Food and Drug Administration are investigating.
