I have never seen a person trying hard to get vaccinated with available vaccines all around them unable to do so. I have seen people attempt to lose weight. The fact that it’s big business is a testament to this.
Sexual behavior, well yea there is careless behavior but also deceit. How would you tell the difference?
With vaccines, the end goal is to get people to get the vaccine so they can live their normal lives. There is no one time simple action someone can take to prevent obesity. There is no vaccine for all stds I’m aware of.
For example, a smoker who is not actively engaged in a smoking cessation program or someone who is morbidly obese by choice and not actively engaged in a medical weight loss program should be paying higher health-insurance premiums to offset their increased costs. (The former is not uncommon and while the latter may be controversial it is not necessarily a niche perspective. [1])
So yes, I think the same logic should apply to individuals who choose not to receive vaccines.
Isn’t that the argument?
Insurance companies have to toe the thin line between a business and a social good. With prediction models to become more and more accurate I would be happier if we have non-profit insurance that amortizes/socializes the draw of the lottery. For voluntary choices of risky behavior, drug addiction, unsafe sex, etc etc., I think insurance companies are within their rights to charge more.
