PCV10 Reactogenicity and Immunogenicity Study - Malindi (PRISM)

February 22, 2018 updated by: KEMRI-Wellcome Trust Collaborative Research Program

Immunogenicity and Reactogenicity of 10-valent Pneumococcal Conjugate Vaccine (PCV10) in Children Aged 12-59 Months

The World Health Organization has recommended that developing countries should incorporate pneumococcal conjugate vaccine (PCV) into their routine immunization schedules. The Kenya Ministry of Health anticipates introducing a new formulation of PCV, PCV10, into the routine childhood immunization schedule in 2010. In the areas of Kenya that have been designated to monitor the impact of vaccine, a catch-up campaign will be implemented to vaccinate children aged 12-59 months. PCV10 has been found to be safe and effective in infants. It is licensed for use in children up to 2 years of age, but its use as a primary series in children over age 12 months has not been evaluated. This study will assess the immunogenicity and reactogenicity of PCV10 first administered at an age of 12-59 months.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
