No combinations of vaccines or viruses can confer invulnerability to future tussles with SARS-CoV-2.

Post-vaccination infections might, in theory, influence immunity in ways our vaccines can’t.

By rousing immune cells that haven’t responded to previous variants, an Omicron infection could effectively “broaden your immune response,” Rishi Goel, an immunologist at the University of Pennsylvania, told me.

Even in the most optimistic scenario, in which a post-vaccination infection does really turbocharge a vaccinated person’s immune responses, the durability of the most primo effects is still a wild card.

The narrative, she's a crumbling.
