Trial summary

After immunization, particularly in older persons, some people are protected from disease by a vaccine and others are not. The investigators believe that this variable response may be due to overproduction of molecules that suppress development of immunity (antibodies and cell mediated immunity).

About this study

Official title: Relationship of Cytokine Production and Immune Responses to Varicella Zoster Virus (VZV) in Elderly Recipients of Zoster Vaccine

After immunization, particularly in older persons, some people are protected from disease by a vaccine and others are not. The investigators believe that this variable response may be due to overproduction of molecules that suppress development of immunity (antibodies and cell mediated immunity). Normally, these molecules are produced to make sure that immunity is regulated in just the right way for the body as a whole, and to prevent autoimmune disease.

However, with aging, the immune system may have difficulty in proper immune regulation. Over production of immunosuppressive molecules after vaccination may interfere with the effects of a vaccine. For example when elderly individuals are immunized against zoster with a licensed vaccine, Zostavax, the vaccine is effective in only about 50 to 60%. The investigators will compare blood levels of antibodies, cellular immunity, and immunosuppressive molecules in recipients of Zostavax to see if there is a correlation between development low immunity and high levels of immunosuppressive molecules.

Read the detailed description

In order to determine whether there is a relationship between production of immunosuppressive cytokines (such as IL-10) an lower levels of immunity to Varicella Zoster Virus (VZV) after vaccination, the investigators will obtain blood samples before and 3-5 times after immunization to determine the immunity to VZV and the levels of certain cytokines. The first blood samples will be obtained before the vaccine is given, as baseline values.

The vaccine being used is the licensed vaccine, Zostavax, which is recommended by the Food and Drug Administration (FDA) and Center for Disease Control and Prevention (CDC) to be administered to all relatively healthy individuals over the age of 50. This study does not concern vaccine safety or effectiveness. As a benefit to vaccines, the vaccine is administered at no charge to the subject.

What participants receive

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

Study groups in NCT01288014
Study groupRoleWhat they receive
Edlerly Recipients of Zoster VaccineBlood samples are collected before and after vaccination in people age 60 or more, who are getting the zoster vaccine as part of their routine health care.

What is being measured

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

  1. Development of antibodies, cellular immunity, and cytokines before and after vaccination

    Measure antibodies, cellular immunity, and cytokines in blood before and after immunization. Determine if there is any relationship between development of strong immunity and development of cytokine levels.

    Measured: Up to week 6

Questions about this trial

What is this clinical trial studying?

An observational study of Immunity; Defect Due to Antibody or Cell Mediated Immune Defect, run by Columbia University at 1 site in United States.

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 1 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 19 Jul 2017. 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 States. 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?

Development of antibodies, cellular immunity, and cytokines before and after vaccination (time frame: Up to week 6). 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 19 Jul 2017.
