Understanding Pneumococcal Carriage and Disease
United Kingdom1,200 participantsStarted 2014-03
Plain-language summary
Pneumococcus is a bacteria that causes disease of the respiratory tract (pneumonia and middle ear infections), blood poisoning, and meningitis. It is frequently carried by people in back of the throat without symptoms. Pneumococcal carriage in the Thames Valley region has been studied over the last 12 years with carriage rates having been shown to be reflective of disease potential and hence vaccine effect. During this time pneumococcal vaccines have been introduced into the routine immunisation schedules of this community. The PCV7 (A vaccine against 7 types of pneumococcus) vaccine has subsequently been noted to have had a significant impact in reducing vaccine serotype carriage and disease. Herd protection (indirect protection of unvaccinated individuals) has also been implicated with vaccine serotypes not being carried in parents of vaccinated children. The most common serotype carried since the introduction of PCV7 is 19A, which is included in the PCV13 vaccine (A vaccine against 13 types of pneumococcus). PCV13 has superseded PCV7 in the routine immunisation schedule, however its impact on carriage and disease in this community is yet to be evaluated.

Inclusion Criteria:
Children
* Parent/guardian of participant is willing and able to give informed consent for participation in the study.
* In good health as determined by a brief medical history and/or clinical judgement of the investigator
* Have received three doses of PCV13 as per infant immunisation schedule (as confirmed by red book or through vaccination history and age). Vaccination history will be confirmed by the child's GP or CHCD. The visit and sampling may still proceed if the vaccination history has not been confirmed beforehand and the participant subsequently excluded if they are found to not have received all three doses of PCV13.Aged 6-48 months and at least 28 days since their third PCV13 vaccination.
* Able (in the Investigators opinion) and willing to comply with all study requirements.
Parents/ Legal guardians
* Participant is willing and able to give informed consent for participation in the study.
* Is the child's legal guardian and lives in the same household with the child participating in the same study.
* In good health as determined by clinical judgement of the research staff
* Able (in the investigators opinion) and willing to comply with all study requirements.
Exclusion Criteria:
The participant may not enter the study if ANY of the following apply:
Children
* Parent/legal guardian unwilling or unable to give written informed consent to participate in the study.
* Parent/legal guardian less than 18 years of age at time of enrolment.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
