About this study

Official title: A Long-Term Safety and Immunogenicity Follow-up of Healthy Adults Vaccinated With One Dose of Smallpox Vaccine (LISTER Strain)

The purpose of this study is to provide long-term follow-up immunogenicity and safety data on participants who were vaccinated with the second-generation smallpox vaccine in Study VVL04 (NCT 00258947).

Primary Objectives:

Immunogenicity: To yearly describe the vaccinia antibody persistence up to 5 years post-vaccination.

Safety: To follow-up the long-term safety up to 5 years post-vaccination.

Read the detailed description

None of the participants in this study will receive any vaccination as part of the study. All participants will provide blood samples for immunogenicity testing at the 1, 2, 3, 4, and 5 year anniversaries of vaccination. Safety will be assessed for up to 5 years after vaccination, including follow-up of reactions that occurred during Study VVL04 (NCT 00258947).

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 1 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 6 Aug 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites 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?

To provide information concerning the immune response of live vaccinia virus (LISTER strain) after primary vaccination. (time frame: 1 to 5 years post-vaccination). The study lists 2 primary outcomes in all. 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 6 Aug 2012.
