Could a Liver-Stage malaria vaccine shield mothers and babies?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Alanine transaminase (ALT) or creatinine (Cr) level above the local laboratory-defined upper limit of normal and ≥ Grade 2 (participants may be included at the investigator's discretion for 'not clinically significant' abnormal values) 6. Infected with human immunodeficiency virus (HIV) 7. Known or documented sickle cell disease by history (Note: known sickle cell trait is NOT exclusionary) 8. Clinically significant abnormal electrocardiogram (ECG) such as abnormal QTc. 9. Evidence of clinically significant neurologic, cardiac, pulmonary, hepatic, endocrine, rheumatologic, autoimmune, hematological, oncologic, or renal disease by history, physical examination, and/or laboratory studies including urinalysis 10. History of receiving any investigational product within the past 30 days 11. Participation or planned participation in a clinical trial with an investigational product prior to completion of the follow-up visit 28 days following last vaccination OR planned participation in an investigational vaccine study until the last required protocol visit 12. Medical, occupational, or family problems as a result of alcohol or illicit drug use during the past 12 months 13. History of a severe allergic reaction (Grade 2 or higher or per PI discretion) or anaphylaxis 14.

Receipt of a live vaccine within the past four weeks or a killed vaccine within the past two weeks prior to Vaccination #1 and every subsequent vaccination day 22. Receipt of immunoglobulins and/or blood products within the past six months 23. Previous receipt of an investigational malaria vaccine in the last ten years 24. Known allergies or other contraindications against use of artemether/lumefantrine 25. Other condition(s) that, in the opinion of the investigator, would jeopardize the safety or rights of a participant participating in the trial, interfere with the evaluation of the study objectives, or would render the participant unable to comply with the protocol
