Prophylactic anti-tumor response. Survival analysis of mice (n = 16, from two independent experiments) injected subcutaneously with 1 × 105 B16.OVA melanoma cells 49 days post immunization with the P1 pentablock gel loaded with blank PLGA-NP (P1 + blank NP), with vaccine-loaded PLGA-NP (P1-NPOVA) or with soluble vaccine (P1 OVA). Unimmunized mice were included as a control (no treatment). Surviving mice were rechallenged 60 days after the initial tumor challenge in the opposite flank with 1 × 105 B16.OVA melanoma cells
