  • Healthy volunteers accepted
  • Child, Adult, Older adult

Study population: One thousand healthy children aged 6-48 months, of which at least 600 will be aged 21-48 months, who have received 3 doses of PCV13 will be recruited along with a subset (200) of their parents/legal guardians

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.

About this study

Official title: Cross-sectional Study to Establish the Point Prevalence of Serotype 19A Pneumococcal Nasopharyngeal Carriage of Fully Vaccinated Children Aged 13-48 Months Following Introduction of PCV13.

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 PCV13 has superseded PCV7 in the routine immunisation schedule, however its impact on carriage and disease in this community is yet to be evaluated.

Questions about this trial

What is this clinical trial studying?

An observational study of Meningitis and Septicaemia, run by University of Oxford at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The presence of serotype 19A pneumococci on children's swabs (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01996007, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jul 2019.
