Someone above pointed out to you that the majority of COVID deaths are in specific populations -- the elderly, the obese, the diabetic, and that "maybe we should think about that", which you replied with "you can't vaccinate against obesity".

Vaccination is just one way to deal with an epidemic.

The WHO coined "globesity" to describe the escalating global epidemic "taking over many parts of the world".

"Its health consequences range from increased risk of premature death to serious chronic conditions that reduce the overall quality of life."
