Symptom narrative

Nurse then got a booster shot of the MMR II in February and had his titers checked in May 2025 and again it showed low protection for Measles but his Mumps and Rubella protection had gone up.; had his titers checked in February 2025 and they showed low in protection for Measles, Mumps and Rubella.; Nurse then got a booster shot of the MMR II in February and had his titers checked in May 2025 and again it showed low protection for Measles but his Mumps and Rubella protection had gone up.; Nurse reports he had his titers checked in 2021 and it showed he did not have the protection for Measles, Mumps and Rubella.; Nurse reports he had his titers checked in 2021 and it showed he did not have the protection for Measles, Mumps and Rubella.; Nurse reports he had his titers checked in 2021 and it showed he did not have the protection for Measles, Mumps and Rubella.; This spontaneous report was received from a Nurse and refers to a 26-year-old male patient. The patient's concurrent conditions included allergic to amoxicillin sodium (+) clavulanate potassium (AUGMENTIN). Historical drugs included amoxicillin sodium (+) clavulanate potassium (AUGMENTIN). Concomitant medications included lisinopril, valacyclovir and emtricitabine (+) tenofovir alafenamide fumarate (DESCOVY). His medical history was not reported. On an unspecified date in 2021, the patient titers showed he did not have the protection for measles, mumps, and rubella (measles antibody negative) (mumps antibody test negative) (rubella antibody negative), following that test, on an unknown date in 2021 (reported as summer of 2021 and given 1 month apart), the patient was vaccinated with the two dose series of measles, mumps, and rubella (wistar ra 27-3) virus vaccine, live (M-M-R II) both administered intramuscular as prophylaxis (Lot numbers, expiration dates, exact dose quantity volumes, anatomical locations of administration and vaccination scheme frequency were not provided); both doses were reconstituted with sterile diluent administered intramuscular (Lot No., expiration date and indication were not reported). On an unknown day in February 2025, the patient titers showed low in protection for measles, mumps and rubella (antibody test abnormal). On an unspecified day in February 2025, the patient was vaccinated with the third dose (reported as booster dose) of measles, mumps, and rubella (wistar ra 27-3) virus vaccine, live (M-M-R II) administered intramuscular as prophylaxis (Lot No., expiration date, exact dose quantity volume, anatomical location of administration and vaccination scheme frequency were not provided) (extra dose administered). On an unspecified date in May 2025, the patient titers showed again low protection for measles but his mumps and rubella protection had gone up (antibody test abnormal) At the reporting time, the outcome of all the events was not reported. The causal relationship between the events of measles antibody negative, mumps antibody test negative, rubella antibody negative, antibody test abnormal (first time) and antibody test abnormal (second time) with the suspect vaccine and the sterile diluent was not provided.
