What other sort of benefit is there supposed to be? The reduction in infection and transmission risk for Delta from the vaccines is marginal at best, wanes quickly, and might well be defeated completely by future variants. If we're acknowledging that the immediate risk tradeoff might be negative, these would be the first vaccines in history that people were widely expected to take on those terms.
> The reduction in infection and transmission risk for Delta from the vaccines is marginal at best, wanes quickly, and might well be defeated completely by future variants. In case you are unaware, reducing the spread of a virus also lowers the odds of sparking new variants, not to mention the fact that limiting or eliminating the spread of a virus also contains and limits the risk posed by new variants.
A similar effect has been observed for leaky vaccines in chickens, where for Marek's disease they actually encouraged the breeding of hotter and more virulent strains.
In terms of playing host to new variants the biggest risk may be the immunocompromised, who are not able to be vaccinated: https://www.washingtonpost.com/health/2021/03/11/immunocompr...
