To do this, four vaccines approved by the U.S. Food and Drug Administration (FDA) will be given simultaneously to participants. Participants will be volumteers who are healthy adults (18 years old or older) and willing to receive the yearly trivalent inactivated influenza vaccine (TIV), the tetanus, diphtheria, and acellular pertussis vaccine (Tdap), the nonvalent HPV (HPV) vaccine, hepatitis A virus (HAV) vaccine and undergo study procedures.\n\nProcedures will include:\n\n* medical history relevant to the study, including medications and vaccines received.\n* Vitals (blood pressure, pulse) and temperature\n* Height and weight.\n* Physical exams.\n* Receive the TIV, Tdap, HPV, and HAV vaccines.\n* Blood samples collected for immunologic tests and genetic analysis.\n* Donate bone marrow by needle aspiration at a maximum of seven visits.\n* Complete memory aid every evening for 7 days after vaccination\n\nOptional Procedures include:\n\n* Donate bone marrow core biopsies at the same visits\n* Ultrasound of lymph nodes and fine needle aspirates of lymph nodes in both arm pits at a maximum of eight separate visits\n\nThere will be a screening visit and and a Day 1 where vaccinations will occur and subsequent visits at Day 8, Day 14, Day 29, Day 57, Day 121, Day 181, Day 366, Day 546, and Day 731.\n\nAt each of these visits health status, vital signs and blood collection will occur.\n\nA bone marrow aspirate and lymph node aspirate will be collected at screening.\n\nThe six additional bone marrow aspirates will be repeated at D29, D91, D181, D366, D546, and D731. The optional bone marrow core biopsy will also be repeated at that time.\n\nUp to seven separate visits will be scheduled for the follow-up lymph node aspirates (D29, D57, D91, D181, D366, D546, and D731)\n\nStudy participation will be 24 months.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.

Currently has symptomatic acute or unstable chronic disease requiring medical or surgical care, to include significant change in therapy or hospitalization, at the discretion of the investigator.\n6. History of excessive alcohol consumption, drug abuse, psychiatric conditions, social conditions or occupational conditions that in the opinion of the investigator would preclude compliance with the study.\n7. Has received any vaccine ≤ 28 days prior to the injection (Day 1) or plans to receive a vaccine within 28 days before or after the study injection. These participants may be rescheduled.\n8. Has received the 2025-2026 influenza trivalent, inactivated vaccine or quadrivalent, inactivated vaccine.\n9.
