Influenza Vaccine in Elderly: Nutritional Status-Dependent Immunogenicity

influenza vaccine

The immune response to influenza vaccine is attenuated in elderly persons, though they are at greatest risk for morbidity and mortality by influenza virus infection. Experimental studies demonstrate that co-administration of L-cystine and L-theanine enhanced antigen-specific production of immunoglobulin in aged mice infected with influenza virus. This study thus investigated the effect of L-cystine and L-theanine on antibody induction by influenza vaccines in elderly persons.

Larch Arabinogalactan and Immune Response

Influenza A

In 2013, a study, Immunomodulatory Effects of ResistAid™: A Randomized, Double-Blind, Placebo-Controlled, Multidose Study, evaluated the ability of a proprietary arabinogalactan extract from the larch tree (ResistAid™, Lonza Ltd., Basel, Switzerland) to change the immune response in healthy adults to a standardized antigenic challenge of tetanus and influenza vaccines in a dose-dependent manner compared to placebo. As it is flu season, Today’s Practitioner is revisiting the study and the subject with an interview with Bryan Rodriguez, Global Products Manager, of Lonza, makers of Resist Aid.
