Over the past several years, new vaccines have become available to prevent serious illnesses and conditions in the adolescent population. Several have already been approved by the FDA for use in this age group; others are still in development. Recently, significant public attention has been focused on the availability of vaccines for several strains of HPV, to prevent both cervical cancer and genital warts. Prior to that, the vaccine for Hepatitis B was approved and recommended for the adolescent age group. Others currently available and recommended include vaccines for pertussis, meningitis, and influenza. In the future, additional vaccines are expected to become available for sexually transmitted and communicable diseases such as herpes simplex virus and HIV. Unfortunately, financial limitations and consent requirements can impede adolescents’ access to the vaccines that are recommended for their age group. However, a variety of policy options exist for overcoming the barriers and expanding access. These policy options are grounded both in international principles of human rights and in the existing framework of laws in the United States, and can be enhanced by attending to variations in age and developmental status among adolescents.
