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

Exclusion Criteria at study entry: * The child has previously received a malaria vaccine. * The child is enrolled in another malaria intervention trial that could interfere with the results of this study. * The child has a history of allergic disease or reactions likely to be exacerbated by any component of the study vaccines. * The child has a history of allergic reactions, significant IgE-mediated events or anaphylaxis to previous immunisations. * The child has major congenital defects. * The child has anaemia associated with clinical signs of symptoms of decompensation, or a haemoglobin of ≤7.4 g/dL. * The child has had a blood transfusion within one month of enrolment. * The child has been administered immunoglobulins and/or any blood products within the three months preceding the planned administration of the vaccine candidate. * The child has malnutrition requiring hospital admission. * The child has an acute or chronic, clinically significant pulmonary, cardiovascular, gastrointestinal, endocrine, neurological, skin, hepatic or renal functional abnormality, as determined by medical history, physical examination or laboratory tests. * Any confirmed or suspected immunosuppressive or immunodeficient state, including HIV or asplenia. * The child has received an investigational drug or vaccine other than the study vaccines within 30 days preceding the first dose of study vaccine, or planned use during the study period. * The child is currently participating in another clinical trial if likely to affect data interpretation of this trial * The child has any significant disease, disorder or situation which, in the opinion of the Investigator, may either put the participants at risk because of participation in the trial, or may influence the result of the trial, or the participant's ability to participate in the trial. * Clinically significant laboratory abnormality as judged by the study clinician * For group 5 only: the child has received any dose of the pentavalent vaccine, pneumococcal vaccine, rotavirus vaccine, IPV or has received more than one dose of the OPV.
