[Active immunization in adolescence].
OBJECTIVE
The purpose of this review is to offer updating on recent changes in the schedule of active immunization routine in adolescence.


METHODS
This review covers specialized medical literature between 1985 and 1996, and follows the recommendations of American Academy of Pediatrics and Advisory Committee on Immunization Practices.


RESULTS
Active immunization in adolescents has been changed in the few last years. New vaccines have been licensed (varicella, hepatitis A), while some old ones have been recommended for routine use (hepatitis B) or as a booster dose (MMR, tuberculosis) at adolescence. This paper reviews these vaccines and the last recommendations concerning their use in adolescents. Special indications of some other vaccines (antiinfluenza, antipneumococcus, etc.) are also mentioned.


CONCLUSIONS
The most recent modifications in the schedule of pediatric immunization routine must be considered in the planning and execution of a comprehensive adolescent health care delivery.
