The word, vaccine has two meanings: 1) Something to prevent the recipient from contracting a disease (the conventional meaning); and 2) Something to treat a disease that’s already incident by harnessing an immune response to a furnished antigen (or antigens)—sometimes called a “therapeutic vaccine.” Note that the second definition includes cases where the incident disease is in remission, as in ADXS’s phase-3 trial of AXAL for adjuvant-setting (non-metastatic) cervical cancer.
Gardasil is case #1 (as are the vaccines for chicken pox, measles, mumps, etc.). AXAL and ADXS’ other pipeline assets are case #2.
