It’s a confusing time right now - in January of 2022, since so many vaccinated people are coming down with omicron. The virus has changed a lot since the vaccines were formulated, but the data show they are still offering partial protection.

I wanted to know how vaccines work in the first place, and how they can protect us after the virus mutates into a new variant. What I learned was that the vaccines kick off a process of Darwinian evolution in your antibody-producing cells.
