.But vaccine study volunteers like nurse Kristen Choi say people preparing for COVID-19 vaccinations need to know what side-effects could happen -- not to scare them away, but to let them know of what to expect when they do get the vaccine, and reassure them that it’s going to be alright.

She wrote about taking part in a Pfizer trial in the summer, in a JAMA article published this week called “A Nursing Researcher’s Experience in a COVID-19 Vaccine Trial.”

She passed the necessary screening, and was soon set up to be one of the trial participants. The trial involved injecting half of the participants with a placebo, and half of them with the experimental vaccine, in order to measure whether the vaccine actually had an effect.

After the first shot, Choi felt fine, and had no idea whether she’d received the placebo or the vaccine. Her second shot, administered the following month, was a different story.

The injection site was much more painful than when she received the first shot, and by the end of the day, she “felt light-headed, chilled, nauseous, and had a splitting headache.”

She fell asleep, but then woke up at midnight, feeling even worse. She was feverish and could barely lift her arm, according to her description on JAMA.

At 5:30 a.m., she woke once again and took her temperature, finding it was a scorching 40.5 degrees Celsius.

“When I saw that I had a high fever, that's the highest fever I can ever remember having,” Choi told CTV News, “I think my initial, just gut reaction was, ‘Do I have COVID somehow?’”

She reported her reaction to the researchers at 9 a.m. when the office opened, and was told that “a lot of people have reactions after the second injection,” and that she should keep monitoring her symptoms.

Both Pfizer and Moderna say their vaccines can induce side-effects similar to the symptoms of COVID-19 infection, including fatigue, chills, headaches, muscle aches and joint pain.

In the case of the Pfizer vaccine, those older than 56 years of age experienced milder side-effects than the younger cohort of 18 to 55 years. The most common side-effects were fatigue and headaches for all ages, with as many as 60 per cent of the younger group experiencing fatigue after their second shot. Only 16 per cent of the younger group had a fever after their second shot, compared to 11 per cent of the older group, according to a briefing document submitted to the FDA.

I ment that her side effects were worse than the majority of people who have had covid. She had a fever of 40.5. A fever above 39.5 is dangerous and above 40 can be life threatening.
