Who may be able to join

  • Completed PCV10 vaccination with 3 or 4 doses (2+1 or 3+1 schedule) before blood sampling at age of 13 months
  • Age at sample collection 13 months, 2 years or 3 years
  • PCV10 vaccination received 2-6 weeks before sample collection at the age of 1 year
  • Informed consent obtained covering the planned analyses

Who cannot join

About this study

Official title: Persistence of Humoral Immunity to Serotype 19A Streptococcus Pneumoniae in Children Vaccinated With the 10-valent Pneumococcal Conjugate Vaccine in Finland

PCV10 2+1 scheduleTen-valent pneumococcal Haemophilus influenzae protein D conjugate vaccine (PHiD-CV10; GlaxoSmithKline) administered with a 2+1 schedule (two vaccinations with minimum 8-week intervals followed by a booster dose at least 4 months after the last primary dose).
Receives: Biological: 10-valent pneumococcal conjugate vaccine, PCV10
PCV10 3+1 scheduleTen-valent pneumococcal Haemophilus influenzae protein D conjugate vaccine (PHiD-CV10; GlaxoSmithKline) administered with a 3+1 schedule (three vaccinations with minimum 4-week intervals, followed by a booster dose at least 4 months after the last primary dose).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Persistence of Humoral Immunity Following PCV10 Vaccination

    Persistence of humoral immunity to vaccine- and vaccine-related pneumococcal serotypes after vaccination with PCV10. The serotype 19A specific geometric mean IgG antibody concentrations are reported as micrograms per ml with 95% confidence intervals.

    Measured: Two years following last PCV10 vaccination

Questions about this trial

What is this clinical trial studying?

An observational study of Pneumococcal Infections, run by Finnish Institute for Health and Welfare at 1 site in Finland.

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 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed 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?

Yes. Results are posted in the registry (first posted 10 Aug 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Persistence of Humoral Immunity Following PCV10 Vaccination (time frame: Two years following last PCV10 vaccination). 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 11 Aug 2021.
