What do you mean by " spirulina doesnot induce any immunological response" ??
It was said that the spirulina increases the production of antibodies and proteins fighting against infection so it can boost the immune response.But now studies confirms that the spirulina supplementation can enhance only the primary immune response to TT vaccine inaccordance with the antibody production. But it is unable to produce secondary immune response following the vaccination in the mouse model. So it is clear that the " spirulina does not induce any immunological response".
