Just to tack on to this - the growth of the virus can be exponential. Seychelles (small island country) was at a high vaccination count but is currently experiencing an outbreak of covid. On the one hand, their case counts are up which sounds bad. On the other hand, they're not seeing the exponential growth in hospitalizations nor deaths - i.e. the vaccines are doing their jobs. Edit-But the effects of the vaccine aren't exponential. You really need to get a good population coverage to axe the thing. And outbreaks can still occur (though less deadly) when/if outsiders come in from populations less vaccinated.
