What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Control group - culture negative | 50 children with pneumococcal culture-negative Acute Otitis Media | |
| study group- culture positive | 50 children with pneumococcal culture-positive Acute Otitis Media |
What is being measured
The primary outcome is the main question the study is designed to answer.
Serological studies of pneumococcal proteins and their development over time following otitis media infections
The serological studies will study the natural immune response to protective pneumococcal vaccine antigens.
Measured: 3 months per individual

Questions about this trial
What is this clinical trial studying?
An observational study of Acute Otitis Media, run by NasVax Ltd at 1 site in Israel.
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 6 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 27 Sep 2011. 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 Israel. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Serological studies of pneumococcal proteins and their development over time following otitis media infections (time frame: 3 months per individual). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 27 Sep 2011; AzTrials last refreshed its copy on 8 Nov 2026.
