My reasoning is that if our goal is to protect the most immune-compromised members of the community—people in whom vaccines provide zero protection against infection let alone severe disease—then perhaps it would be acceptable to drop indoor mask mandates when case counts are low enough that the highest-risk adults can attend to something like daily living and have less than a 1% chance of becoming infected with SARS-CoV-2 in a 4-month period.
We could protect immunocompromised people if we cared.
