>>At an incredibly reduced rate, and mutations generally do not spread to others. It's a fast enough where Iceland is now experiencing its largest wave yet, despite having a nearly fully vaccinated population. And why would vaccination stop mutated strains from spreading? >>I don't see how that's relevant to my original response. It's relevant to whether any one country has cause to mandate vaccination. >>Mutations occur irrespective of any human constructs such as nations, countries, borders, etc. My point is that - even if vaccination affected the size of the infected population and thus the opportunity for the virus to mutate - one country's decision to vaccinate will not meaningfully affect the global vaccination rate and therefore the global mutation rate.
