(Participants with conditions that can be treated prior to enrolment such as cerumen obstruction are not excluded)\n* History of acute or chronic or severe neurologic condition (eg, diagnosis of Guillain-Barré syndrome, epilepsy, Bell's palsy, meningitis, or disease with any focal neurologic deficits).\n* Current of past significant risk factors for hearing loss (eg, occupational exposure to loud noise or medical illness) that, in the opinion of the investigator, may interfere with the detection of changes in hearing during the study.\n* History of any condition associated with sensorineural hearing loss that, in the opinion of the investigator, may cause changes in hearing during the study (eg, occupational exposure to loud noise or medical illness).\n* If, in the opinion of the PI, it is not in the best interest of the participant to participate in the study.","18 Months","70 Years",{"count":179,"type":20},612,[123],[126],"2025-05-07",{"date":184,"type":38},"2025-05-11",{"date":186,"type":38},"2024-03-06",{"date":188,"type":20},"2027-04",{"name":190,"class":191},"International AIDS Vaccine Initiative","NETWORK",3,""]
