* Prior residence for ≥6 months continuously in a malaria-endemic region as defined per CDC (https://www.cdc.gov/malaria/travelers/country\_table/a.html) at any point during their lifetime.
* Breastfeeding or intending to become pregnant or to father children starting with Visit 0 and continuously until 90 days after receiving Dose 3.
* History of any serious adverse reactions to vaccines or to vaccine components such as lipids, and including history of anaphylaxis and related symptoms such as hives, respiratory difficulty, angioedema, and/or abdominal pain. (Not excluded from participation: a volunteer who had an anaphylactic adverse reaction to pertussis vaccine as a child).
* Current or history of the following medical conditions:
1. Uncontrolled or moderate or severe respiratory diseases (e.g., asthma, chronic obstructive pulmonary disease); symptoms of asthma severity as defined in the US National Asthma Education and Prevention Program Expert Panel report, 2020 - e.g., exclude a volunteer who:
* Uses a short-acting rescue inhaler (typically a beta 2 agonist) daily, or
* Uses high dose inhaled corticosteroids (per American Academy of Allergy Asthma and Immunology), or
* In the past year has either of the following:
* Greater than one exacerbation of symptoms treated with oral/parenteral corticosteroids
* Needed hospitalization, or intubation for asthma.
2. History of Diabetes mellitus type 1 or type 2, including cases controlled with diet alone or elevated hemoglobin A1C ≥6.5% at screening (not excluded: history of isolated gestational diabetes).
3. Hypertension:
* If a person has a history of hypertension, or elevated blood pressure detected during screening, exclude for blood pressure that is not well controlled. Well controlled blood pressure is defined as consistently ≤140 mm Hg systolic and ≤90 mm Hg diastolic, with or without medication, with only isolated, brief instances of higher readings, which must be ≤150 mm Hg systolic and ≤100 mm Hg diastolic at screening and enrollment.
4. Malignancy within 5 years of screening, excluding localized basal or squamous cell skin cancer.
5. Any current or history of cardiovascular diseases, (e.g., myocarditis, pericarditis, myocardial infarction, congestive heart failure, cardiomyopathy or clinically significant arrhythmias), unless such disease is not considered relevant for participation in this trial in the investigator's judgment.
6. An abnormal screening ECG (i.e., showing the corrected QT interval by Fridericia \[QTcF\] greater than 450 ms; significant ST-T wave changes suggestive of myocardial ischemia or of an acute or indeterminate-age myocardial infarction; left ventricular hypertrophy; any non-sinus rhythm including isolated premature ventricular contractions; complete right or left bundle branch block \[QRS greater than 120 ms\]; second-or third-degree atrioventricular block); or other clinically significant abnormalities on the ECG at the investigator's discretion.
7. Bleeding disorder diagnosed by a doctor (e.g., factor deficiency, coagulopathy, or platelet disorder requiring special precautions).
8. Seizure disorder: History of seizure(s) within the past 3 years or has used medications in order to prevent or treat seizure(s) at any time within the past 3 years.
* Documented major psychiatric illness, including bipolar disorder, major depressive disorder, schizophrenia, autism, and attention deficit-hyperactivity disorder that at the discretion of the investigator could interfere with participation and follow-up as outlined by the trial.
* The following diseases associated with immune dysregulation:
* Primary immunodeficiencies.
* History of solid organ or bone marrow transplantation.
* Asplenia: any condition resulting in the absence of a functional spleen.
* Currently existing or history of autoimmune disease including and not limited to thyroid autoimmune disease, multiple sclerosis, psoriasis, etc.
* Previous vaccination with an approved or investigational malaria vaccine at any time or having taken part in a human malaria challenge study.
* Receipt of any investigational product within 28 days before Visit 0.
* Any planned non-trial vaccinations starting at Visit 0 and continuously until 28 days after Dose 3.
* Note: Seasonal influenza and Coronavirus Disease 2019 (COVID-19) vaccines are allowed; however, they should be administered at least 14 days before or 28 days after any IMP administration. Emergency vaccinations, such as tetanus, are allowed to be administered when medically indicated.
* Received blood/plasma products, monoclonal antibodies or immunoglobulin within 120 days before Visit 1 or planned administration starting at Visit 0 and continuously until the last trial visit (365 days after Dose 3).
* Received allergy treatment with antigen injections within 28 days before and after each IMP administration.
* Current or planned treatment with immunosuppressive therapy, including systemic corticosteroids (if systemic corticosteroids are administered for ≥14 days at a dose of ≥20 mg/day of prednisone or equivalent) starting at Visit 0 and continuously until 28 days after Dose 3. Intraarticular, intrabursal, or topical (skin or eyes) corticosteroids are permitted.
* Have a history of alcohol abuse or drug addiction within 1 year before Visit 0 or have a history (within the past 5 years) of substance abuse, which in the opinion of the investigator, could compromise their wellbeing if they participate as participants in the trial, or that could prevent, limit, or confound the protocol specified assessments.
* Any existing condition which may affect vaccine injection and/or assessment of local reactions at the injection site, e.g., tattoos, severe scars, etc.
* Are vulnerable individuals as per International Council for Harmonisation (ICH) E6 definition, i.e., are individuals whose willingness to volunteer in a clinical trial may be unduly influenced by the expectation, whether justified or not, of benefits associated with participation, or of a retaliatory response from senior members of a hierarchy in case of refusal to participate.
* Any screening hematology and/or blood chemistry laboratory value (per the US FDA 2007) that meets the definition of a Grade ≥2 abnormality or a Grade 1 abnormality at the investigator's discretion at Visit 0 or a Visit 0 troponin above the reference range. Individuals with abnormal but not clinically significant parameters not included in the toxicity guidance may be considered eligible at discretion of investigator, with the exception of abnormal troponin values.
