Trial summary

In France, vaccination coverage is insufficient (in 2002, 71.2% coverage for tetanus, 41.9% for poliomyelitis and 33.7% for diphteria). These numbers decrease significantly with age: coverage for people aged over 65 was 60.5%, 13.3% and 10.5% for tetanus, poliomyelitis and diphteria coverage respectively. Read more about this study

About this study

Official title: Evaluation of a Tdap-IPV Vaccination Remedial Strategy on Vaccination Coverage in Patients 65 Years of Age or Older in the French County of Sarthe

In France, vaccination coverage is insufficient (in 2002, 71.2% coverage for tetanus, 41.9% for poliomyelitis and 33.7% for diphteria). These numbers decrease significantly with age: coverage for people aged over 65 was 60.5%, 13.3% and 10.5% for tetanus, poliomyelitis and diphteria coverage respectively.

The primary objective of this study is to evaluate the impact of a hospital based vaccination remedial strategy for Tdap-IPV (tetanus, diphteria, pertussis and polio vaccine) in patients 65 years of age or older.

Secondary objectives are to measure the vaccination coverage of patients aged 65 years or older hospitalised in a medical ward in our hospital, to evaluate their knowledge of their vaccination coverage, and to evaluate the socio-demographic factors associated with vaccination coverage.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Remedial vaccinationBiological

    • if the patients vaccinations are up to date: no remedial vaccination is done and the patient is informed of the next remedial vaccination date
    • if the patients vaccinations are not up to date: remedial vaccination is realised in the unit in the absence of contraindication, in case of a temporary contraindication the vaccination will be performed on an outpatient basis by the patients primary care provider and he will be given a prescription at hospital discharge for the remedial vaccination.

What is being measured

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

  1. Change in immunization rate after a hospital centered remedial strategy for Tdap-IPV vaccination in patients 65 years or older

    Difference in the increase in vaccination coverage between the two arms, measured as a percentage

    Measured: two months

Secondary outcomes (4)
  1. Immunisation rate among patients 65 years of age or older in the Sarthe department of France

    Pre-intervention vaccination coverage rate in both arms, measured as a percentage

    Measured: two months

  2. Immunisation rate according to sex among patients 65 years or older

    Sex of patients included in the study

    Measured: two months

  3. Immunisation rate according to primary care coverage among patients 65 years of age or older

    Primary care coverage is defined as having a regular primary care physician registered as such with French social security.

    Measured: two months

  4. Immunisation rate according to socio professional category

    Socio professional category defined according to the French national institute for statistics and economic studies (INSEE)

    Measured: two months

Questions about this trial

What is this clinical trial studying?

A study testing Remedial vaccination in people with Vaccination, run by Centre Hospitalier le Mans at 1 site in France.

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 3 inclusion and 4 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 1 Jul 2026. 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 France. 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?

Change in immunization rate after a hospital centered remedial strategy for Tdap-IPV vaccination in patients 65 years or older (time frame: two months). 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 1 Jul 2026.
