Unapproved age; Interchange of vaccines; This non-serious case was reported by a nurse via call center representative and described the occurrence of inappropriate age at vaccine administration in a female patient who received DTPa (Reduced antigen) (Boostrix) (batch number 9532Y, expiry date 23-MAY-2025) for prophylaxis. Previously administered products included adacel (received her four doses at 9th, 18th, 16th months and 26th months). On an unknown date, the patient received the 1st dose of Boostrix. On an unknown date, an unknown time after receiving Boostrix, the patient experienced inappropriate age at vaccine administration (Verbatim: Unapproved age) and interchange of vaccine products (Verbatim: Interchange of vaccines). The outcome of the inappropriate age at vaccine administration and interchange of vaccine products were not applicable. This report is made by GSK without prejudice and does not imply any admission or liability for the incident or its consequences. Additional Information: GSK Receipt Date: 12-MAY-2025 Reporter stated that a child five years old, was seen at children's for her last erasion, she was in line with her immunizations. However, when she went to the hospital this last erasion, they decided to give her a tdap, she is five, she got the tdap which was Adacel. So, apparently, while they were there, the provider decided that child needed the tdap shot, because they had four shots but not a fifth of her dtap. They wanted to know if they need to perform another dtap, if they have already an adult tdap that was given, given that the child already received her four others at 9th, 18th, 16th months and 26th months and they turned around and gave her this tdap, in this past year. Also wanted to know if she is covered then given the amount in this vaccine, is it appropriate dosing or do they need to give her another dtap or what. She actually had, those previous four doses, were pentacels. The patient received Boostrix at the age of 5 years after four doses of Adacel, which led to interchange of vaccine products and inappropriate age at vaccine administration.
