New Strategies to Improve Therapeutic Vaccines

Abstract

Vaccination represents a viable and attractive strategy for therapeutic treatment of cancers by the power of a patient's own immune system. Major advances in cellular and molecular immunology have led to the approval of the first therapeutic cancer vaccine by FDA. However, the development of cancer vaccines remains infant. Maximizing the therapeutic efficacy while minimizing side effects of the therapeutic cancer vaccine remains key challenges to this field. In this review, we summarized the recently developed strategies to induce anti-tumor responses in vivo to improve the outcomes of cancer vaccines, with an emphasis on the guiding principles that are critical for rational design of effective and safe vaccines against cancers.
