Clinical narrative: Lower Respiratory Tract Infection (LRTI); Upper Respiratory Infection (URI); This 9-month-old male subject was enrolled in a blinded study. The subject received the 3rd dose of Bexsero vs Placebo co-administered with PCV and routine vaccines (intramuscular, left thigh) on 15-FEB-2019, for prophylaxis. The subject received DTPa-HBV-IPV on an unknown date. The subject received the 2nd dose of Rotarix lyophilized formulation (oral) on 07-DEC-2018, for prophylaxis. The subject received the 3rd dose of Hiberix (intramuscular, right thigh) on 15-FEB-2019, for prophylaxis.   Co-suspect products included Prevenar 13 (Non-GSK Comparator) (Prevenar 13) for prophylaxis.   On 07-MAY-2019, 81 days after receiving Bexsero vs Placebo co-administered with PCV and routine vaccines and Hiberix, an unknown time after receiving DTPa-HBV-IPV and 151 days after receiving Rotarix lyophilized formulation, the subject developed moderate - grade 2 lower respiratory tract infection (Verbatim: Lower Respiratory Tract Infection (LRTI)). Serious criteria included hospitalization and GSK medically significant. Additional event(s) included moderate - grade 2 upper respiratory tract infection (Verbatim: Upper Respiratory Infection (URI)) on 07-MAY-2019 with serious criteria of hospitalization. The subject was treated with ceftriaxone sodium (Ceftriaxone), ipratropium bromide (Ipratropium), ibuprofen sodium (Ibuprofen), prednisolone sodium phosphate (Orapred) and salbutamol sulfate (Albuterol). Rotarix lyophilized formulation was continued with no change. The outcome of lower respiratory tract infection was resolved on 09-MAY-2019. The outcome(s) of the additional event(s) included upper respiratory tract infection (resolved on 09-MAY-2019).   Relevant Tests: On 08May2019 Chest X-ray results: left lung has patchy opacity in the midportion superimposed on the fourth anterior rib. Mild airway thickening is noted.

The investigator considered that there was no reasonable possibility that the lower respiratory tract infection and upper respiratory tract infection may have been caused by Bexsero vs Placebo co-administered with PCV and routine vaccines, DTPa-HBV-IPV, Rotarix lyophilized formulation and Hiberix.

INVESTIGATOR TEXT 5/8/19: Subject presented to the clinic with increased work of breathing, decreased activity  and urine output for 24 hours. PI saw her immediately and performed physical, also monitoring O2 stats. Subject also had elevated temperature of 100.2F. Initial sat 90-91%; was given 3 nebs, 10 mg steroid burst. After first neb PI felt that the subject was in respiratory distress and called EMS. After 3rd neb treatment, air flow appeared to be improved, but with continued considerable retractions and wheezing felt subject should be transported to ER. ER ordered chest x-ray and labs.  Chest X-ray results: "left lung has patchy opacity in the midportion superimposed on the fourth anterior rib. Mild airway thickening is noted. Cardiac and mediastinal contours are normal. No pneumothorax or pleural effusion. No acute osseous abnormality."

Findings were concerns for pneumonia, subject was treated with IV and antibiotics. ER Physician felt he need to be admitted for observation overnight.  5/9/19: Subject was discharged with diagnosis of Viral Upper (URI) and Lower Respiratory Tract (LRTI) Infections. Instructions to follow up with PCP 5/13 or 5/14 or with ER if needed.  Upon internal review the case was updated on 18-Mar-2025. Comparator vaccines updated.  Follow up information received on 11-Mar-2025 End of study Unblinding completed.; Sender's Comments: A case of the Lower respiratory tract infection and Upper respiratory tract infection, 81 days after receiving Placebo and 3rd dose of DTPa-HBV-IPV and Hiberix,  2nd dose of Rotarix lyophilized formulation, and Prevenar 13 in a 9-month-old male subject. Placebo case following unblinding, causality assessment non applicable.  Report is inconsistent with causal relation to the vaccine product, considering an implausible time to onset and absence of biological plausibility.
