Streptococcus pneumoniae, commonly called pneumococcus, can cause a wide range of diseases in children from mild ear infections to deadly pneumonia or meningitis. Vaccination is currently the single best way to protect children. Nutrition, especially the amount of vitamin A, may play a role in how well your body responds to infection or a vaccine. We call this an immune response. This research will look to see if children who take a vitamin with their vaccine have a better immune response than children who do not take a vitamin with their vaccine. Primary Objective To evaluate the influence of vitamin A supplementation on Prevnar vaccine immunogenicity based on changes in antibody scores in a commercial ELISA at Day 21 (after a booster vaccine dose) compared to pre-vaccine values. Secondary Objectives To evaluate the relationship between baseline vitamin levels and pneumococcal or hepatitis A vaccine antibody responses (based on in commercial ELISAs) at Days 0 and 21. To evaluate the influence of vitamin A supplementation on hepatitis vaccine immunogenicity based on changes in antibody scores in a commercial ELISA at Day 21 compared to pre-vaccine values. To evaluate relationships between total serum antibodies (based on individual IgM, IgG1, IgG2, IgG3, IgG4, and IgA scores in a Luminex assay) at Day 0 and changes between Days 0 and 21 with baseline (Day 0) vitamin levels in young children, and with vitamin A supplementation.

This study will assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of AZD2389 following single and multiple dose administration (SAD/MAD) to healthy participants. Read Less

The purpose of the study is to learn how different forms of a study medication called danuglipron are taken into the blood in healthy adults. Read Less

The purpose of this study is to investigate the safety of multiple oral doses of Lu AG06474, how well the doses are tolerated, and what the body does to the drug after administering it to healthy young participants. This study also aims to compare how the body absorbs and uses Lu AG06474 when it is given in capsule form versus when it is given as an oral solution. Read Less

The purpose of this study is to compare two formulations of PF-07220060 in terms of their uptake into the blood stream. The study will assess the effects of food and Rabeprazole on the uptake of PF-07220060. Rabeprazole belongs to a type of medications called proton pump inhibitors. In reality, some patients may take both PF-07220060 and rabeprazole together. This study is seeking participants that are: - Healthy male or female aged 18 to 65 years All participants in this study will receive PF-07220060 once by mouth. The participants may receive different tablets for PF-07220060. Some participants will take a meal before receiving PF-07220060. In addition, some participants will take rabeprazole by mouth for 7 days before taking PF-07220060. The study will compare experiences of people receiving two different formulations of PF-07220060. Experiences of people taking food and rabeprazole with PF-07220060 will be compared to those on PF-07220060 alone. This will help understand how much PF-07220060 is taken up into the blood. It will also help understand how meal and Rabeprazole medicine changes the uptake of PF-07220060 into the blood. Participants will take part in the study for a maximum of 71 days. During this time, they will have to stay onsite for 5 to 11 days. There will be up to 2 onsite study visits. Read Less

This study will consist of 2 parts. The study will evaluate whether administration of phenytoin impacts the single-dose drug levels of afimetoran and BMT-271199 (Part 1) and will evaluate whether multiple administrations of afimetoran impact the drug levels of midazolam and 1-hydroxymidazolam (Part 2).

The purposes of this study are to: Learn about the safety and tolerability of CK 4021586 after a single dose and multiple doses in healthy subjects. Find out how much CK-4021586 is in the blood after a single dose and multiple doses. Determine the effect different doses of CK-4021586 on the pumping function of the heart. Determine the effect of food in the stomach on how much CK-4021586 is in the blood after a single dose. Read Less
