In March 2025, the patient received dose of mRNA-1273.712 (SPIKEVAX 2024-2025 PFS) (unknown route) 1 dosage form. In March 2025, the patient experienced DECREASED APPETITE (loss of appetite), ILLNESS (desperately sick from the March vaccine), URTICARIA (hives/ the ones patient had before, patient thinks, had all been on the right), FATIGUE (fatigue) and HEADACHE (headache). In 2025, DECREASED APPETITE (loss of appetite), ILLNESS (desperately sick from the March vaccine), URTICARIA (hives/ the ones patient had before, patient thinks, had all been on the right), FATIGUE (fatigue) and HEADACHE (headache) had resolved. No concomitant medication was reported. The patient's side effects were usually pretty much the same. The patient always had side effects that start around 3 in the afternoon because she always gets the vaccines early in the morning. They subside by nighttime the next day. At the time of current vaccination (Spikevax LP.8.1 PFS), her usual side effects - headache, fatigue, loss of appetite - were milder time in comparison to the vaccine she had in March. The patient was desperately sick from the March vaccine but did not have itchy rash at the injection site plus the hives that come and go on different parts of her body. The patient always plans it when she did not have important things to do the day after the COVID vaccine because she knows that she was going to be real sick. The current hives she had right now were on her right leg but the ones before, she thinks, had all been on the right. The patient did not remember but her feeling was that it was on her right hand and right arm. It was unknown if the patient experienced any additional symptoms/events. No treatment medication was reported. This case was linked to MOD-2024-773529 (Patient Link).
