Math. Specifically exponents.
1. The vaccines do reduce the spread.
2. Vaccines and natural immunity reduce severity: More severe covid will provide exponentially more mutation opportunities than less severe disease.
3. Cross-reactive immunity from existing natural or vaccine-induced immunity will mitigate many potential mutations.
People who have some existing immunity (which is getting to be most of us) provide less mutation opportunity.
