related_tweet: @goldiluxes @jonathan_jobe @kavitapmd omicron only has an r0 near 2. its transmissibility mainly occurs through its short serial interval. so, herd immunity would be reached at 50% population immunity, and we overshot that by at least 10%. i would think 60% immunity/resistance to omicron would be present now.
