ALACOVID Study for Vaccinated Subjects

In this study, it is hypothesized that administration of 5-ALA-Phosphate + SFC in subjects vaccinated against Covid-19 could contribute in enhancing the targeted function of the immune system, which might lead to re-activation and/or increase of the vaccination response. Thus, in the present study, we will be evaluating the safety and efficacy of 5-ALA-Phosphate + SFC in subjects receiving the Covid-19 vaccine.
