11. Fever

Dr. Fauci has said to expect possibly getting “a fever.” Although it is likely to be mild, Choi described the severe fever she experienced:

“When I woke up again at 5:30 am, I felt hot. Burning. I took my temperature and looked at the reading: 104.9 °F (40.5 °C). This was the highest fever I can ever remember having, and it scared me. I took acetaminophen and drank a glass of water. When the research office opened at 9 am, I called to report my reaction to the injection. Thankfully, my fever had come down to 102.0 °F (38.9 °C) by then.”
