sore shoulder or sore injection site; very very bad chills; Fever of 101°F; This spontaneous case was reported by a consumer and describes the occurrence of VACCINATION SITE PAIN (sore shoulder or sore injection site), CHILLS (very very bad chills) and PYREXIA (Fever of 101°F) in a 79-year-old male patient who received mRNA-1273.251 (Spikevax LP.8.1 PFS) for COVID-19 prophylaxis. Previously administered products included for COVID-19 prophylaxis: SPIKEVAX NOS (patient had 9 Moderna shots in his arm from the beginning of the pandemic). Past adverse reactions to the above products included No adverse effect with SPIKEVAX NOS. On 17-Sep-2025, the patient received dose of mRNA-1273.251 (Spikevax LP.8.1 PFS) (Intramuscular use) 1 dosage form. On 26-Sep-2025, the patient experienced VACCINATION SITE PAIN (sore shoulder or sore injection site), CHILLS (very very bad chills) and PYREXIA (Fever of 101°F). On 27-Sep-2025, VACCINATION SITE PAIN (sore shoulder or sore injection site), CHILLS (very very bad chills) and PYREXIA (Fever of 101°F) had resolved. DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On 26-Sep-2025, Body temperature: 101 F (just under 102 fever). No concomitant medications were reported. The site of vaccine administration was reported as 'shoulder'. The patient had no other side effects since then; it could be a delayed reaction even though it was 9 days later. This strain of SARS was a pretty bad strain so his body may have taken a few days to react to it. After suspect administration, 9 days later he came down with chills, eventually within a couple of hours of getting the chills, developed just under 102 fevers. That lasted until 27-Sep-2025. They said that they had had 9 Moderna shots since the COVID disease began. Both of them had only taken Moderna shots. Most of the shots had been pretty uneventful, with regular side effects, but it was the first time one of them had experienced little weird effects. No treatment medications were reported.
