It will be quite hard to “eradicate” Covid around the world, but with luck vaccines will provide lasting immunity, enough to end the pandemic, return life to more or less normal, and prevent tens of millions of deaths. Empirically, SARS-CoV-2 mutates much more slowly than influenza viruses, and if a new strain eventually pops up that the vaccine and people’s antibodies do not work on, the current vaccines should be faster to modify than to recreate from scratch.
