PD-L1 Long(19-27) Peptide sequence: FMTYWHLLNAFTVTVPKDL Dose: 100 µg PD-L1 long1 dissolved in DMSO/water - Total volume: 0,5 ml.
ArgLong2(169-206) Peptide sequence ISAKDIVYIGLRDVDPGEHYILKTLGIKYFSMTEVDRL Dose: 200 µg ARGLong2 dissolved in DMSO/water - Total volume: 0,5 ml.
Both vaccines are given at a treatment. Adjuvant Montanide ISA 51 0,5ml is mixed with the peptides before treatment To be administered every second week - a total of twelve times, with a possibility of additional six treatments.

- Immune response [ Time Frame: 1 year ]T-cell cytokine release towards target antigens
- Adverse events evaluated by CTCAE v. 5.0 [ Time Frame: 1 year ]Adverse events are graded 1-5 according to the criteria
- Clinical response [ Time Frame: 10 year ]Vaccinations will induce clinical response in 2 patients, either partial response or better, according response criteria for PV and ET or clinical response as a reduction of mutated allelic burden - 10% from baseline at any time.
