Some people are justifying the mRNA vaccines as ethical under the ethical principle of “right to try”, which I fully agree with. What I disagree with is the propaganda campaign surrounding the vaccine along with the deliberate overestimation of its effectiveness and underestimation of its danger. Every adult should have the power to make their own decisions about their health, and if an un-licensed but promising drug or treatment exists, they deserve to have the option to try it if it has the potential to save their life.
But by the same principle there should be included an option to be deliberately exposed to the virus itself in a controlled environment, with treatment at the ready, rather than awaiting a chance infection somewhere down the line.
