Getting everyone vaccinated in the United States has become much harder now that demand for the Covid-19 vaccine is flagging. America’s vaccination strategy needs to change to address this, and it starts with understanding the specific reasons people have not been vaccinated yet.
The conventional approach to understanding whether someone will get vaccinated is asking people how likely they are to get the vaccine and then building a demographic profile based on their answers: Black, white, Latinx, Republican, Democrat. But this process isn’t enough: Just knowing that Republicans are less likely to get vaccinated doesn’t tell us how to get them vaccinated. It’s more important to understand why people are still holding out, where those people live and how to reach them.
