More unvaccinated people -> more people getting covid -> more chances for mutation into variants
It's really that simple. We want as few active infections as possible globally so that existing vaccinations can work for the variants they were made in mind with. Otherwise we will be at the disadvantage in a perpetual arms race trying to quickly stamp out the global "fires" of new variants.
