When COVID-19 vaccines became available, Colorado public health officials initially relied on mass vaccination events publicized through Facebook, email and texts, and required Coloradans to book appointments online.
But when that go-big strategy drove large disparities in who was getting vaccinated, public health departments in the Denver area decided to go small instead.
They provided microgrants, small sums for one-time projects, to community organizations serving immigrants and minorities, and allowed those groups to determine how best to use the money.
Some used apps and social media, including WhatsApp, Nextdoor and Facebook Live. Others chose to pound the pavement and knock on doors. Vaccine promotion events occurred at Saturday soccer games and at the Mile High Flea Market.
