My understanding is that they're not sure if the vaccine will last in your system for more than 30 years, and that subsequent doses may be less effective, so getting it early may weaken you later.
But I am with you. My personal bet is we'll know more about this by the time that becomes an issue.
The earliest cohorts of vaccinated children are approaching their 30s, so we should learn about long term efficacy this decade.
How much fertilizer does the Iowan farmer need to add to their field to achieve that? How many years can they maintain that yield without eroding the soil?
No one electron goes the 1600 mile distance. An increase of cheap energy supply in one place lowers likelihood of production elsewhere, but it is more diffuse than selling Iowan energy in California.
I find similar happening with Gemini Pro. Despite paying for Pro, it regularly locks me out, without visibility into consumption. Nothing on the plan comparison page indicates limits. https://one.google.com/about/plans
I use a variant of access tracking by treating things like stacks.
