Here is a link to a new video which argues that the existing public health measures of lockdowns and contact tracing are ultimately inadequate to deal with Covid-19. It takes a holistic health perspective, including examining the role of proper nutrition and vitamins, especially vitamin D3, material of which has been covered at this site in previous posts. A good, all round sum up, that you can recommend to family and friends, especially older folk, who are the ones mostly at risk. And, the disclaimer needs to be made these days, that this is for public interest only, and is not offered as medical and health advice.
