Coincidentally, given the recent outbreaks of measles and whooping cough in California, CDSS recently issued a revised form for CalWORKs recipient families who seek a good cause exception to the child immunization requirements. As of March 1, 2015, counties must use the revised Immunization Good Cause Request Form (CW 2209) which allows families to explain why one or all eligible children in the assistance unit are not immunized or cannot show proof of immunization. The form must be provided at the time of application, redetermination and whenever the county requests proof of immunization. Families are still permitted to make a verbal good cause request.
