That's all very true. But the vaccines are doing a damn good job and they are tweakable. They are the only hope of defeating the virus, unless it eventually defeats itself, which seems unlikely. What is important is that we don't allow ourselves to be sidetracked by snake oil remedies. All they do is help to perpetuate the crisis by allowing people to feel far more secure than is justifiable. We simply can't have the recommending of evidence-innocent vitamin remedies, the criticising of non-mask wearers yet the defending of people who won't take the vaccine. In the vast majority of cases there is no moral defence for vaccine refusal.
