Detailed Description

This is a randomized, double-blind placebo controlled pilot study designed to determine effect size on altering blood inflammatory biomarkers and anti SARS-CoV-2-specific adaptive response including memory T cell, memory B cells and antiviral antibody titers. The participants will have a variety of clinical manifestations that will include varying degrees of fatigue, cognitive dysfunction and other PASC-related symptoms. Individuals will be randomized by site to receive either Immulina or placebo given daily for 8 weeks followed by a 4 week observation off supplement.
