The American Association on Intellectual and Developmental Disabilities (AAIDD) released a research brief this month. The purpose of this brief is to provide an overview of what the research to date reveals about people with intellectual and developmental disabilities (IDD), COVID-19, and vaccination. The research to date indicates that people with IDD (a) are more likely to be exposed to COVID-19 and have poorer COVID-19-related health outcomes than the general public; (b) are as likely as the general population to engage in preventive health strategies; and (c) have experienced massive disruption in health, home, and community services, exacerbating existing inequities in health care and putting additional pressure on already overtaxed formal and informal support networks.

AAIDD also shared this resource, which offers research, commentary, and editorials concerning COVID-19. It is searchable by keyword.
