mRNA vaccines, explained by Vox

Good explainer on how the new vaccines work (and a primer on the old ones too). What an achievement by the scientific community to be able to create it so quickly. There's still so much to be done before we're out of this pandemic. Having the vaccine might protect you, but we might need to continue with various restrictions until we're sure it's gone. It's already mutated a handful of times and what happens if we let our guard down and it mutates in a way that the vaccines are no longer effective against it?
