Fucoidans boost immune response to the influenza vaccine

12.20.2018

In the November issue of the Journal of Nutrition, scientists report an improved immune response in subjects taking fucoidans. Fucoidans are sulfated polysaccharides found in edible seaweed. They’ve been previously shown to have anti-viral and immunomodulatory effects.


Men and women over the age of 60 participated in a stratified randomized, placebo-controlled, double blind study in

Osaka, Japan. They were split into one of two groups, receiving either 300 mg of Mekabu Fucoidan (MF) or placebo during a 4 week period. All 70 volunteers received a seasonal influenza vaccine of 3 viral strains. Blood samples were taken prior to vaccination and after the fifth and 20th week to measure antibody titers and natural killer cell activity.


Compared to the placebo group, participants taking the fucoidans had higher antibody titers against all 3 viral strains, with the most benefit seen for the B/Brisbane/60/2008 antigen. High titers were maintained over 20 weeks after vaccination. The MF group also exhibited increased natural killer cell activity after 9 weeks.


“Our study showed a possible adjunctive role of MF in antibody production in the elderly, although further studies on the underlying immunomodulatory mechanisms are needed. It is hoped that the popular seaweeds eaten daily in Japan, though almost unknown around the world as a nutritional source, will be consumed outside Japan for possible immunopotentiation and for attenuating the burden of infectious diseases in the elderly.”
