Solidly within the covid scenario as it exists modernly.
Any 30yo say that believes they are morally responsible for say a 70 yo person's specific health is sorely mistaken..ie Any 70yo that thinks any random 30 year old (say) holds a moral responsibility to them for their health is exhibiting immoral/utilitarian/psychopathic thought.
I would feel ashamed if another thought I expected them to vaccinate for my health, I simply do not have that right...I might hope but if even slightly considered myself a decent person could never expect let alone demand (low metacognitive psychopaths all of those that demand)
Frontal lobes have not changed in thousands of years.
