We cordially invite you to the next PIVAC meeting “The 23rd International Conference on Progress in Vaccination Against Cancer” (PIVAC-23) which will be held from 28th –30th September 2023 in Athens, Greece at the Saint Savvas Cancer Hospital, 171 Alexandras avenue, 11522, Athens.

PIVAC 23 aims to bring together scientists working on translational and clinical cancer research for three days of presentations on the most recent advances in these fields  including (i) immunotherapies (cellular, immune checkpoint blockade, vaccines); (ii) innate immunity and tumor control; (iii) host- tumor interactions in the tumor microenvironment; (iv) in vitro and in vivo models for cancer immunotherapies (v) combinational cancer therapy approaches; and (vi) prognostic and predictive biomarkers in tumors and immune cells.

Improved knowledge of genomic and molecular alterations in tumors has significantly contributed to improved clinical outcomes. However, many hurdles remain to be overcome. Alterations in the tumor genome are associated not only with immune stimulation but also with an immune suppressive microenvironment and tumor immune escape mechanisms. Currently, various promising novel approaches are being employed to improve the efficacy of immunotherapies alone or in combination with targeted therapies, often by seeking to reverse the immunosuppressive environment. Additionally, prognostic signatures are being sought in order to provide a basis for tailored immunotherapies.

During the meeting there will be plenty of time for fruitful discussions between speakers and participants to encourage the emergence of new collaborations.

On behalf of the Organizing Committee, we are pleased to invite you to participate in this Meeting.
