I got my first dose of COVID vaccine yesterday. But I'm not sure I haven't already had COVID twice. In February of '20, a nasty cough went around my household and persisted for a month. Then, over the past several weeks I've been recovering from another three-week episode of coughing and congestion. No fever or ague, though. Given that it's likely the majority of COVID cases are asymptomatic or low-symptom, I'm not sure I haven't already had the damned thing. But getting a test is more of a hassle than getting the vaccination, and recovery from the virus doesn't preclude getting the vaccination, so I'll never really know.
