Door knocking works to get information to immigrant communities. Why aren’t more places using it for Covid-19?

Kica Matos wants to knock on every single door in her neighborhood. But this isn’t a run-of-the-mill political effort: She’s using the canvassing playbook to sign people up for Covid-19 vaccine appointments.
