(Leah Hogsten | The Salt Lake Tribune) Samantha Lopez, 4, is comforted by her sister Genesis, 9, and her father Bernardo Lopez as she receives a total of three vaccine shots. The Community Assistance and Resource Event (CARE) Fair offers free physical exams, dental cleanings, child and adult immunizations, disease screenings and mental health assessments to patients of all ages on first-come, first-served basis. What started 25 years ago as free immunizations for about 300 children has transformed into a community resource that has served nearly 70,000 people.
