I was just like frozen; pain with body aches; body aches; This spontaneous case was reported by a consumer and describes the occurrence of MOVEMENT DISORDER (I couldn't hardly move. I was just like frozen), PAIN (pain with body aches) and MYALGIA (body aches) in a 71-year-old female patient who received mRNA-1273.712 (SPIKEVAX 2024-2025 PFS) for COVID-19 prophylaxis. The suspect product included Pre-filled Syringe injection for COVID-19 prophylaxis and non-company product included Influenza vaccine (Flu) for an unknown indication. Previously administered products included for COVID-19 prophylaxis: Spikevax NOS (Patient took the Moderna shot 2- 2.5 years ago and it didn't bother her. During the pandemic, she got a little sick, but she had taken the Moderna shot and so she didn't get very sick.). Past adverse reactions to the above products included No adverse effect with Spikevax NOS. Concurrent medical conditions included Endometrial cancer (The patient stated that she had endometrial cancer, but Keytruda had almost eliminated it at that point. She added that she was still receiving infusions every three weeks and had been on the treatment for over 2.5 years.). Concomitant products included Pembrolizumab (Keytruda) for Endometrial cancer. In November 2024, the patient received dose of mRNA-1273.712 (SPIKEVAX 2024-2025 PFS) (Intramuscular use) 1 dosage form and dose of Influenza vaccine (Flu) (unknown route) 1 dosage form. On an unknown date, the patient started Pre-filled Syringe (unknown route) at an unspecified dose. In 2024, the patient experienced MOVEMENT DISORDER (I couldn't hardly move. I was just like frozen), PAIN (pain with body aches) and MYALGIA (body aches). In 2024, MOVEMENT DISORDER (I couldn't hardly move. I was just like frozen), PAIN (pain with body aches) and MYALGIA (body aches) had resolved. It was reported that in the previous year, she had taken her flu shot and her COVID-19 shot about two to three weeks apart, around the second to fourth week of November. She stated that after receiving the vaccine, she experienced what she described as a terrible reaction. She clarified that it was not related to her heart, as she had read about such issues, but explained that she had felt almost frozen and was in severe pain with body aches, barely able to move. She mentioned that this condition lasted for at least 12 hours and possibly up to 24 hours. She expressed disbelief at the severity of the reaction and recalled thinking that she hoped she would be okay. The patient added that she was now considering not taking the Moderna vaccine again but then thought that it might have been reformulated. She said she was thinking about taking the Pfizer vaccine instead because a friend in (withheld) had taken Pfizer without any problems. The patient emphasized her worry about the previous year's reaction although she eventually recovered. She described herself as healthy apart from requiring Keytruda for cancer treatment and noted that her heart and overall health were otherwise good. She was unable to provide lot numbers for the vaccines. It was unknown if the patient experienced any additional symptoms or events. Treatment medication was not reported.
