RCT of Mushroom Based Natural Product to Enhance Immune Response to COVID-19 Vaccination (MACH19)

Multicenter Double-Blind, Placebo-Controlled RCT of Fomitopsis Officinalis/Trametes Versicolor for COVID-19

This is a randomized, double-blind, placebo-controlled clinical trial to evaluate the effect of two polypore mushrooms, Fomitopsis officinalis and Trametes versicolor (FoTv), for use as an adjunct to vaccination for COVID-19 in a general population at the time of COVID-19 vaccination.

This is a randomized, double-blind, placebo-controlled clinical trial to evaluate the effect of two polypore mushrooms, Fomitopsis officinalis and Trametes versicolor (FoTv), for use as an adjunct to vaccination for COVID-19 in a general population at the time of COVID-19 vaccination. Fo and Tv have immunomodulatory properties which may increase antibody titers in response to vaccination more than vaccination alone. However, because they are also immunomodulatory - not purely immune-stimulating - they may have the added benefit of simultaneously decreasing vaccine-related side effects following COVID-19 vaccination. The study aims to establish the safety and feasibility of the use of FoTv vs placebo; evaluate the effect on post-vaccination clinical symptoms, neutralizing antibody, and immune response in 45 total subjects

Drug: FoTv The dosage of FoTv is 8 capsules three times a day for 4 consecutive days. It does not need to be consumed with food. It is best taken at least 30 minutes before OR at least 60 minutes after meals, in the morning, noon and evening. Accidentally missed doses will not need to be taken at a later time but will be recorded in a daily diary. Should swallowing capsules be an issue, they can be opened and dispensed into water or juice for easy ingestion.

Placebo: organic brown rice The dosage of Placebo is 8 capsules three times a day for 4 consecutive days. It does not need to be consumed with food. It is best taken at least 30 minutes before OR at least 60 minutes after meals, in the morning, noon and evening. Accidentally missed doses will not need to be taken at a later time but will be recorded in a daily diary. Should swallowing capsules be an issue, they can be opened and dispensed into water or juice for easy ingestion.

The safety of the study medication will be assessed by a comparison of the serum creatinine level of baseline laboratory data with end-of-treatment labs

The safety of the study medication will be assessed by a comparison of the serum AST level of baseline laboratory data with end-of-treatment labs

The safety of the study medication will be assessed by a comparison of the serum ALT level of baseline laboratory data with end-of-treatment labs

The safety of the study medication will be assessed by a comparison of the serum albumine level of baseline laboratory data with end-of-treatment labs

The safety of the study medication will be assessed by a comparison of the serum bilirubin level of baseline laboratory data with end-of-treatment labs

The safety of the study medication will be assessed by a comparison of the serum electrolyte levels of baseline laboratory data with end-of-treatment labs

The effect of study medication will be assessed by a comparison of the plasma antibody titer among subjects in active arm compared with placebo

Objective will be to evaluate post-vaccination symptoms duration (number of days) among subjects in the active arm compared with placebo

Objective will be to evaluate post-vaccination symptoms severity total score among subjects in the active arm compared with placebo

Exploratory objective will be to evaluate immune response to COVID-19 vaccination in the presence of FoTv compared to placebo arm
