CAIR can refer to two different things, depending on the context:

1. Council on American-Islamic Relations: This is a Muslim civil rights and advocacy group that challenges anti-Muslim discrimination nationwide. It was founded in June 1994 to combat the devastating effects of stereotyping and defamation on American Muslims. CAIR conducts research on the American Muslim community, releases annual reports on public opinion and demographic statistics on the community, and sponsors voter registration drives and outreach, and interfaith relations with other religious groups in America.

2. California Immunization Registry (CAIR): This is a secure, confidential, statewide computerized immunization information system for California residents. It is accessed online to help providers and other authorized users track patient immunization records, reduce missed opportunities, and help fully immunize Californians of all ages. Providers in most of California use the CAIR2 system which is supported by a centralized Help Desk and local support staff. The greater San Joaquin Valley, utilizes different software (RIDE) to access patient immunization records.
