NCT04533061

Brief Summary

This a sub-study of a 5-year study designed to investigate how antibody and T cell responses following influenza vaccine compare among lung transplant patients, patients waiting for lung transplantation, and healthy individuals. This trial is designed to investigate the hypothesis that there is no difference in T Cell response to the influenza vaccine between lung transplant patients and healthy controls.

Outcome Measures

Primary Outcomes (2)

  • Antibody response to influenza vaccine

    Blood was drawn prior to and 2-4 weeks after immunization and used to measure antibody responses by hemagglutination inhibition assay

    2-4 weeks post-immunization (2004-2005 season), up to 1 year (2-4 weeks post-immunization, 2005-2006 season)

  • T cell response to influenza vaccine antigens

    T cell response is measured with trans-vivo delayed-type hypersensitivity assay (TVDTH). To induce TVDTH responses, prepared lymphocytes were injected into the footpads of anesthetized (isoflurane) severe combined immunodeficiency (SCID) mice using a 0.5 ml syringe with a 28-gauge needle. The resulting swelling is an index of human T cell sensitization.

    between January and April 2005, between January and April 2006

Study Arms (2)

Lung Transplant, Vaccine

Cohort consist of individuals who have received lung transplants Inactivated influenza vaccine will be administered intramuscularly annually.

Drug: Influenza vaccine

Healthy Control, Vaccine

Cohort consists of healthy individuals who received the influenza vaccine Inactivated influenza vaccine will be administered intramuscularly annually.

Drug: Influenza vaccine

Interventions

influenza vaccine 0.5 ml intramuscularly each season 2004-2005 season contains: A/New Caledonia/20/99 (H1N1)-like, A/Fujian/411/2002 (H3N2-like), and B/Shanghai/361/2002-like antigens 2005-2006 season contains: A/New Caledonia/20/99 (H1N1)-like, A/California/7/2004 (H3N2), and B/Shanghai/361/2002-like antigens
