Got my first vaccine shot yesterday. Went very smoothly. No symptoms, not even a bruise or soreness. Did some research and basically, I still need to protect myself for two weeks, which I believe is the outside level, so at least a week before any effects. First dose effective anywhere from 58-85% after two weeks. (No certainty in this uncertain world.) Then a full two weeks after the second dose for full immunity. So basically, I'm looking at five weeks of being careful and double masking.
