The David Geffen School of Medicine at UCLA requires that all incoming students obtain a health clearance from the UCLA Student Health Service for personal protection and community health reasons. The health clearance requirements include a physical examination including diagnostic tests; positive hepatitis B antibody test; and demonstration of immunity to tetanus, diphtheria, rubella, measles and mumps (including re-immunization with measles, mumps, and rubella if the immunization occurred prior to 1980; and proof of a tetanus/diphtheria booster within the last 10 years.) A pertusis with the tetanus/diphtheria booster (DPT) is strongly recommended. In addition, all students must be monitored for tuberculosis (skin test) annually during all years.

Students must have everything except the hepatitis B vaccines and titer completed by the first day of class otherwise, they may not be allowed to start classes. Additionally, if starting or continuing a hepatitis b series, this must be completed before the first day of the first year spring semester or will not be eligible to continue the second semester.
