From clinical trials starring Cod LIver Oil, "Ethics" section
"In conclusion, the study has a low risk of negative health-or other effects on participants and a high probability of identifying whether cod liver oil can prevent Covid-19 and other respiratory infections. Furthermore, the encouraging preliminary data suggests that the morbidity caused by Covid-19 will be significantly reduced in the cod liver oil group adding to the benefit of the study. Further adding to the benefit is the prospect of collecting high-quality data on the more general health effects of cod liver oil use. In total, we consider that the benefits of the study far outweigh the risks and disadvantages"
