AI-assisted case summary:
On March 5, 2026, Constantia Kyrou filed a petition alleging an adverse reaction to an influenza vaccine administered on October 23, 2023.

The court identified that Ms. Kyrou already had an earlier Vaccine Program petition, No. 25-253V, based on the same vaccine administration and alleged adverse reaction. Because the Vaccine Act allows only one petition for the same vaccine administration, Chief Special Master Brian H. Corcoran issued a show-cause order.

On March 9, 2026, petitioner acknowledged that the new petition duplicated the earlier case and requested dismissal. The court treated the response as a notice of dismissal under Vaccine Rule 21(a)(1) and dismissed the duplicate petition without prejudice on March 10, 2026. The public order does not describe the medical condition or award compensation.

Theory of causation field:
Influenza vaccine on October 23, 2023, allegedly causing an adverse reaction; DISMISSED WITHOUT PREJUDICE as duplicative of earlier case No. 25-253V. No medical merits ruling, no diagnosis detail, no award. Chief SM Brian H. Corcoran, petition filed March 5, 2026; dismissal March 10, 2026.

ORDER CONCLUDING PROCEEDINGS1
On March 5, 2026, Constantia Kyrou filed a petition for compensation under the
National Vaccine Injury Compensation Program, 42 U.S.C. § 300aa—10 through 34.2
Petitioner alleged that she suffered an adverse reaction to an influenza vaccination that
she received on October 23, 2023. ECF No. 1 at 1.
Upon review, it was discovered that Petitioner had filed an earlier case (no. 25-
253V3) claiming the same adverse reaction from the same October 23, 2023 influenza
vaccine. Pursuant to § 300aa—11(b)(2), “only one petition may be filed with respect to
each administration of a vaccine.” An order instructing Petitioner to show cause why this
case should not be dismissed as a duplicate petition was issued on March 6, 2026. ECF
No. 6. On March 9, 2026, Petitioner filed a response to the order to show cause
acknowledging that this case contained a duplicate claim to Petitioner’s earlier case and
requesting the court dismiss the current claim. ECF No. 7 at 1.
In light of the above, I interpret Petitioner’s response as a “notice of dismissal”
pursuant to Vaccine Rule 21(a)(1). This case is dismissed without prejudice.
Accordingly, this Order hereby notifies the Clerk of Court that proceedings “on the
1 Because this Order contains a reasoned explanation for the action taken in this case, it must be made
publicly accessible and will be posted on the United States Court of Federal Claims' website, and/or

Act of 2002. 44 U.S.C. § 3501 note (2018) (Federal Management and Promotion of Electronic
Government Services). This means the Order will be available to anyone with access to the internet.
In accordance with Vaccine Rule 18(b), Petitioner has 14 days to identify and move to redact medical or
other information, the disclosure of which would constitute an unwarranted invasion of privacy. If, upon
review, I agree that the identified material fits within this definition, I will redact such material from public
access.

should be entered by the Clerk’s Office.
IT IS SO ORDERED.
