The discussion here, lead me to following thoughts.
I think the key with human challenge trial is that the people infected would be volunteers.
Unlike Bernie Sanders, I do not think that letting someone die is equal to killing them.
Unlike Bernie Sanders, I do not think reducing taxes on the rich is giving money to the rich.
Though I support a UBI, unlike Bernie Sanders, I do not think not taxing people and giving the money to people less rich is equal to inflicting poverty on them.
Unlike Bernie Sanders, I do not think not providing healthcare to people is equal to denying them healthcare. Though it might make sense to provide cheap stuff like vaccinations and many other very high bang for the bucks (trauma care infant care, some meds) things paid for through taxes, BUT at our discretion.
