The patient's medical history, concurrent conditions, and concomitant therapies were not reported. On 15-DEC-2025, the patient was inadvertently vaccinated with Pneumococcal 21-valent Conjugate Vaccine (CAPVAXIVE) 0.5 mL administered as prophylaxis (lot number reported as Z013052, which has been verified as valid, expiration date reported and validated as 30-MAY-2027) (route of administration and anatomical site of injection were not reported), instead of Pneumococcal 15-valent Conjugate Vaccine (VAXNEUVANCE) due to product confusion (Wrong product administered, Product confusion). The reporter said that the medication error was definitely product confusion as all of their previous vaccines were indicated for both adults and infants so it could be confusing having this product (CAPVAXIVE) that was only indicated for adults. No symptoms were reported.
