Immune and Hormone Response to Influenza Vaccine

December 6, 2018 updated by: Johns Hopkins Bloomberg School of Public Health

A Pilot Study of the Immune Response to Influenza Vaccination and Effect on Reproductive Hormones

The purpose of this pilot research project is to look at the effect of the inactivated influenza vaccine (seasonal flu shot) on early signs of immune or germ-fighting response known as cytokines or signal molecules. The investigators also want to see if the timing of vaccine administration has any effect on women's reproductive hormones. The investigators hypothesis is that influenza vaccine given right before ovulation may change the hormone levels usually seen after ovulation. Thi

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is an open-label, longitudinal study of healthy young women of reproductive age, not on hormonal contraception who receive seasonal inactivated influenza vaccine (IIV). The women will be followed for one menstrual cycle to measure luteinizing hormone surge, estradiol, and progesterone, and then vaccinated with the seasonal inactivated influenza vaccine prior to ovulation during a second month. At the investigator's discretion, or if there is active circulation of influenza virus in Baltimore, the investigators will vaccinate during the first menstrual cycle (prior to ovulation) and then follow for a second menstrual cycle for comparison. After vaccination, they will be followed for cytokine and chemokine responses as well as changes in the concentrations of steroid hormones. This study will evaluate the effect of IIV on inflammatory cytokines and hormonal responses before and after ovulation. Each woman will have 13 visits in addition to a screening visit, and will be followed for 2 complete menstrual cycles.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 39 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment.
