Medical Studies on Melatonin
Melatonin reduces the mortality of severely-infected COVID-19 patients
SARS-CoV-2 has ravaged the population of the world for two years. Scientists have not yet identified an effective therapy to reduce the mortality of severe COVID-19 patients. In a single-center, open-label, randomized clinical trial, it was observed that melatonin treatment lowered the mortality rate by 93% in severely-infected COVID-19 patients compared with the control group (see below). This is seemingly the first report to show such a huge mortality reduction in severe COVID-19 infected individuals with a simple treatment. If this observation is confirmed by more rigorous clinical trials, melatonin could become an important weapon to combat this pandemic.
The Coronavirus Disease 2019 (COVID-19): Key Emphasis on Melatonin Safety and Therapeutic Efficacy
Viral infections constitute a tectonic convulsion in the normophysiology of the hosts. The current coronavirus disease 2019 (COVID-19) pandemic is not an exception, and therefore the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, like any other invading microbe, enacts a generalized immune response once the virus contacts the body.
A preliminar study of a neuroimmune regimen with low-dose angiotensin 1-7 plus melatonin to improve the safety of covid 19 vaccine
In experimental conditions, it has been demonstrated that vaccine efficacy and the toxicity is depending on cytokine-induced immunoinflammatory response, and that they may be modulate through a neuroimmune approach, which neuroendocrine agents, such as the pineal hormone melatonin (MLT) and the enzymatic product of ACE2, the angiotensin 1-7 (Ang 1-7). On these bases, a preliminary study was planned to evaluate the influence of an oral peri-vaccination regimen with MLT plus Ang 1-7 on the subjective safety of Covid19 Pfizer-BioNTech (PF) and AstraZeneca (AZ) vaccines.

Blood melatonin level can serve as a potential biomarker for prostate and hepatocellular carcinomas
Many systemic functions display circadian rhythms driven by an endogenous mechanism that is regulated by circadian-related genes and these gene expressions control a central clock in the brain and subordinate clocks in peripheral tissues. However, modern life has introduced environmental factors that often interfere with natural circadian rhythms. Importantly, circadian disruption has been identified as an independent risk factor of cancers.

Plasticity of glucose metabolism in activated immune cells: advantages for melatonin inhibition of COVID-19 disease
COVID-19 has infected hundreds of thousands and killed tens of thousands of people worldwide and it continues to ravage societies as well as fiscal and economic stability of several countries. Currently, several drugs that were designed for other conditions have been repurposed to counter the COVID-19 pandemic. Some have modest efficacy in resisting this disease, but all of them have significant toxicity. Several pharmaceutical companies are rushing to develop vaccines, but their availability is 8 to 12 months in the future. In the meantime, readily available and affordable molecules that will have utility as COVID-19 antidotes are being sought.
Melatonin, cardiovascular disease and COVID-19: A potential therapeutic strategy?
The mechanism for SARS-CoV-2 infection is the requisite binding of the virus to the membrane-bound form of angiotensin-converting enzyme 2 (ACE2) and internalization of the complex by the host cell. SARS-CoV-2 induced endothelial dysfunction and cardiovascular injury are probably initiated by increases in the phosphorylation levels of JAK2 and STAT3 and resultant reactive oxygen species (ROS) formation. These pathological alterations are speculated to be strikingly reversed by melatonin.
