Clinical narrative: Viral Gastroenteritis; This 12-month-old male subject was enrolled in a blinded study. The subject received the 4th dose of Bexsero vs Placebo (intramuscular) on 5th March 2020, for prophylaxis. The subject received the 3rd dose of DTPa-HBV-IPV (intramuscular) on 10th September 2019, for prophylaxis. The subject received the 2nd dose of Rotarix lyophilized formulation (oral) on 9th July 2019, for prophylaxis. The subject received the 3rd dose of Hiberix (intramuscular) on 10th September 2019, for prophylaxis. The subject received the 1st dose of M-M-R II (subcutaneous) on 5th March 2020, for prophylaxis. The subject received the 1st dose of Varivax (subcutaneous) on 5th March 2020, for prophylaxis.   Co-suspect products included dtpa-hbv-ipv vaccine pre-filled syringe device injection syringe for prophylaxis, rotavirus vaccine oral applicator device (Rotarix Oral Applicator Device) oral applicator for prophylaxis and Prevnar 13 (Non-GSK Comparator) (Prevnar 13) for prophylaxis.   On 10th March 2020 14:45, 5 days after receiving Bexsero vs Placebo, M-M-R II and Varivax, 182 days after receiving DTPa-HBV-IPV and Hiberix and 245 days after receiving Rotarix lyophilized formulation, the subject developed severe - grade 3 viral gastroenteritis. Serious criteria included clinically significant/intervention required. The subject was treated with sodium chloride (Sodium Chloride 0.9% Bolus) and ondansetron (Zofran (Ondansetron)). The outcome of viral gastroenteritis was recovered/resolved on 17th March 2020.   The investigator considered that there was no reasonable possibility that the viral gastroenteritis may have been caused by Bexsero vs Placebo, DTPa-HBV-IPV, Rotarix lyophilized formulation, Hiberix, M-M-R II and Varivax.

INVESTIGATOR TEXT Patient presented to Wake Med ED on 3/10/2020 for vomiting that started that day. In the ED he had several episodes that were blood streaked- non bilious. HE received Zofran and boluses of IV fluids. His lab work was reassuring. Prior to departure from the ED he had a large bowel movement that appeared to have blood and mucus. An ultrasound was obtained to rule out obstruction and /or intussusception, and that was negative. Stool studies were sent out and pending at the time of discharge 3/11/20 morning. His vomiting and diarrhea were suspected to be secondary to viral gastroenteritis. At followup office visit on 3/12/20 additional stool studies were obtained (Giardia, Cryptosporidium, Ova and parasite, Shigella, stool pathogen panel, salmonella, campylobacter) and all resulted negative. The diagnosis was presumed to be a viral gastroenteritis.        Additional deatils: On 30Jun2021 SAE Diarrhea was deleted.  Follow up information received on 11-Mar-2025 End of study Unblinding completed.; Sender's Comments: A case of gastroenteritis viral, 5 days after receiving the 4th dose of Bexsero vs Placebo, M-M-R II, Varivax, 182 days after receiving 3rd dose of DTPa-HBV-IPV vaccine pre-filled syringe device injection syringe, 182 days after receiving 3rd dose of Hiberix  and 245 days after receiving 2nd dose of Rotarix vaccine oral applicator device in a 12 month old male subject. Report is inconsistent with causal relation to the vaccine product, considering absence of biological plausibility.
