Clinical narrative: localize reaction where the CAPVAXIVE was administered on the upper right arm/the patient reported burining and itching over and around the affected injection site area; localize reaction where the CAPVAXIVE was administered on the upper right arm/the patient reported burining and itching over and around the affected injection site area; the skin looked like "it may break and begin weaping" in the affected area with "fissure cracks"; localize reaction where the CAPVAXIVE was administered on the upper right arm/reddened, and warm to the touch; Localize reaction where the CAPVAXIVE was administered on the upper right arm/reddened, and warm to the touch/the patient reported burning over and aro8und the affected injection site area; localize reaction where the CAPVAXIVE was administered /almost as big as a grapefruit/the reaction was bigger/ and had spread to approximately 1-2cm beyond the circled border near the bottom "where gravity would pull it down"; Low grade temperature; Significant discomfort; Body/bone aches; Body/bone aches; This spontaneous report was received from a nurse practitioner and regarding to a 56-year-old female patient. The patient's medical history included hypertension and history of respiratory infection, actinic keratosis, basal cell carcinoma upper extremity and eyelid, fair skin and blond hair.

On 11-MAR-2025, the patient started therapy with pneumococcal 21-valent conjugate vaccine (CAPVAXIVE) INJ 168 mcg/ml, 0.5 mL, once, via injection intramuscular (IM) on the upper right arm, lot number Y013009 (lot number Y013009 had been verified to be valid lot number for, expiration date was reported as 17-DEC-2025, but upon an internal validation, established as 17-NOV-2025), as 56 range vaccination (prophylaxis).

The HCP described the reaction on 13-MAR-2025, as being "significant" and almost as big as a grapefruit, reddened, and warm to the touch, so the HCP circled the borders of the reaction site and prescribed sulfamethoxazole;trimethoprim (BACTRIM) because she was concerned about cellulitis, and told the patient to return if the reaction became larger than the circled ring. The patient returned to the HCP on 14-MAR-2025, because the reaction was bigger and had spread to approximately 1-2cm beyond the circled border near the bottom "where gravity would pull it down" and approximately 1cm beyond the circled border near the top shoulder and posterior part of the arm, additionally, the HCP stated the skin looked like "it may break and begin weaping" in the affected area with "fissure cracks" and the patient reported burning and itching over and around the affected injection site area.
