COVID-19 vaccination is critical for public and individual health; transportation is essential for most people to get vaccinated. This toolkit collects emerging best practices and advice to help nonprofits, communities, and mobility providers improve vaccine access for older adults, particularly those who are homebound, no longer drive, have a disability, worry about vaccine safety, or lack family/caregiver support. Our thanks to The Harry and Jeanette Weinberg Foundation for their support, as well as the many and diverse partners of Age Friendly Arizona and the Rural Transportation Incubator. Explore the toolkit for tip sheets, an introduction with executive summary, video profiles of programs and strategies, and resources and tools organized by topic in the left column below.
