On an unknown date, the patient received Boostrix. On an unknown date, an unknown time after receiving Boostrix, the patient experienced inappropriate age at vaccine administration (Verbatim: Boostrix out of the recommended age multiple administrations). The outcome of the inappropriate age at vaccine administration was 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: 27-JUN-2025 The health care provider wanted to confirm that GlaxoSmithKline did not have a vaccine recommended for children from 7 to 10 for Diphtheria and Tetanus Toxoids and Acellular Pertussis immunization and mentioned that because of that, she was giving Boostrix to the patients in that range of age, which led to an inappropriate age at vaccine administration. The agent read the information found on the prescribing information of Boostrix, including the part of dosage and administration where mentioned cases where it could be given out the recommended age and offered to put on hold while searching further information (and if not, contacting second line) but the health care provider declined and mentioned that she was following the centers for disease control's recommendation, to which the agent reply that still would be needing to gather the data of the patients in between those ages that received the vaccine, but the health care provider commented that she would be needing to go back in the past and search all of the patients that she gave the vaccine to, because she received a lot from different countries and moved onto trying to collect the agent's contact details, so there was not the cooperation needed to collect the adverse event data. The vaccine administration facility was the same as primary reporter.
