4. History of severe adverse reaction associated with a vaccine and/or severe allergic reaction (eg, anaphylaxis) to any component of the study intervention(s).
5. Immunocompromised individuals with known or suspected immunodeficiency, as determined by history and/or laboratory/physical examination.
6. Bleeding diathesis or condition associated with prolonged bleeding (including use of anticoagulant medications within 7 days prior to enrollment) that would contraindicate IM injection or imply treatment or prophylaxis of known cardiac or valvular disease. Note: The use of ≤325 mg of aspirin per day as prophylaxis is permitted, but the use of other platelet aggregation inhibitors, thrombin inhibitors, Factor Xa inhibitors, or warfarin derivatives from 7 days prior to enrollment through conclusion of study participation is exclusionary.
7. Other medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study. This includes a history of alcohol or drug abuse as determined by the investigator.
8. Women who are pregnant or breastfeeding.
9. Prior history of heart disease (eg, heart failure, coronary artery disease, cardiomyopathies, pericarditis/myocarditis, or uncontrolled hypertension).
10. Participant with a history of autoimmune disease including, but not limited to, systemic or cutaneous lupus erythematosus, autoimmune arthritis/rheumatoid arthritis, multiple sclerosis, idiopathic thrombocytopenia purpura, glomerulonephritis, autoimmune thyroiditis, temporal arteritis, psoriasis, and/or insulin dependent diabetes mellitus.
11. Previous vaccination with any varicella or HZ vaccine.
12. Individuals who receive treatment with immunosuppressive therapy, including cytotoxic agents or systemic corticosteroids, eg, for cancer or an autoimmune disease, or planned receipt throughout the study. If systemic corticosteroids have been administered short term (<14 days) for treatment of an acute illness, participants should not be enrolled in the study until corticosteroid therapy has been discontinued for at least 28 days before study intervention administration. Inhaled/nebulized, intra-articular, intrabursal, or topical (skin or eyes) corticosteroids are permitted.

Participation in observational studies is permitted. Note: This criterion does not apply to participants who are participating in a follow-up period for another study involving an investigational drug or vaccine, if receipt of the last dose was at least 6 months prior to consenting for this study and there is no further dosing anticipated from the previous study during the participant's participation in this study.
16. Any screening hematology and/or blood chemistry laboratory value that meets the definition of a ≥ Grade 1 abnormality; or any abnormal bilirubin or troponin I value. Note: Any abnormal bilirubin or troponin I value above the ULN reference range is exclusionary. Participants with any stable Grade 1 abnormalities (according to the toxicity grading scale), except bilirubin and troponin I, may be considered eligible at the discretion of the investigator. (Note: A "stable" Grade 1 laboratory abnormality is defined as a report of Grade 1 on an initial blood sample that remains less than or equal to Grade 1 upon repeat testing on a second sample from the same participant during the screening period (prior to Visit 1). Please refer to the laboratory normal ranges (provided separately in the central laboratory manual) for grading scales for abnormalities.
17. Screening 12-lead ECG that, as judged by the investigator, is consistent with probable or possible myocarditis/pericarditis or demonstrates clinically relevant abnormalities that may affect participant safety or interpretation of study results. Participants with a screening 12-lead ECG that shows an average QTcF interval >450 msec, complete LBBB, signs of an acute or indeterminate-age myocardial infarction, ST-T interval changes suggestive of myocardial ischemia, second- or third-degree AV block, or serious bradyarrhythmias or tachyarrhythmias should be excluded from study participation.
18. Participation or planned participation in strenuous or endurance exercise within 7 days before or after each study intervention administration.
