Participants will be subject to follow-up for 12 months after receiving a single booster dose of GBP510 adjuvanted with AS03.\n\nBlood sampling for cell-mediated immunity will be undertaken on approximately 20% of the participants in each cohort, who are selected in advance in consideration of the randomization ratio between Test Group and Placebo Group.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '19 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.

Any other conditions which might interfere with the evaluation of the study objectives (e.g. alcohol or drug abuse, neurologic or psychiatric conditions).\n10. Female participants who are pregnant or breastfeeding.\n11. History of drug administration other than COVID-19 vaccination intended to treat or prevent COVID-19.\n12. History or planned other vaccination within 4 weeks prior to the study vaccination through 28 days after the study vaccination (except for influenza vaccination, which may be received at least 2 weeks prior to the study vaccination).\n13. Receipt of immunoglobulins, whole blood or blood products within 12 weeks prior to the study vaccination.\n14. Use of immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy for at least 2 consecutive weeks within 12 weeks prior to the study vaccination or long-term systemic corticosteroid therapy (e.g. ≥10mg prednisone/day or equivalent for more than 2 consecutive weeks) (However, the use of topical and nasal glucocorticoids will be permitted.)\n15.
