Exclusion criteria

Exclusion criteria: Receiving monoclonal antibodies or biotherapies altering the immune response, other than anti-CD20 antibodies in the chemotherapy protocol. - Previous vaccination with PCV13 or PPV23 (unless PCV13 was administered in childhood. The last injection must be performed at least five years ago). - Preexisting condition that altered the immune response: splenectomy, HIV, primary or secondary immune deficiency, nephrotic syndrome, sickle cell anemia, autoimmune disorder, solid organ transplantation, immunosuppressive drugs or biotherapy not included in the chemotherapy. - Patient who already received chemotherapy for malignancy in the previous 2 years before the inclusion. - Allogeneic hematopoietic stem cell transplantation planned in the following 3 months after the first chemotherapy course. - Curative anticoagulation within 7 days before vaccination. - Major blood clotting disorders preventing intramuscular injection. - Medical history of anaphylactic reaction to vaccination. - Known allergy to one of the vaccine components. - Involvement to another vaccine biomedical research. - Protected person. - Pregnant women or women of childbearing age without appropriate contraceptive measures. - Perfusion of polyvalent immunoglobulins during follow-up.

Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the immunogenicity of the combined pneumococcal vaccination strategy (one injection of PCV13 followed 2 months later by an injection of PPV23) 1 month after the complete vaccination regimen in adult subjects treated with cytotoxic chemotherapy for AML or lymphoma. ;Secondary Objective: - Evaluation of the immunological response after PCV13 injection at 4 weeks. - Evaluation of the durability of the immunological response at 3-6 months after injection of PPV23. - Evaluation of the durability of the immunological response of the combined vaccination strategy at 9-12 months after the injection of PPV23 - Study the pneumococcal IgA, IgM, IgG and IgG2 total IgG levels at 4 weeks after PCV13 injection, and at 4 weeks, 3-6 months and 9-12 months after PPV23 injection and correlation them with the response to vaccination as determined by the reference method. - Determination of early and late pneumococcal vaccine response factors in the AML and lymphoma population. - Evaluation of the clinical tolerability and safety of the combined vaccination strategy in the AML and lymphoma population. - Evaluation of the concordance between the reference test (WHO ELISA) and an industrial kit (Vacczyme® Binding Site®). ;Primary end point(s): Proportion of patients having a good response to combined strategy at 4 weeks after the end of the combined strategy. A good response to vaccination is defined by 4/7 tested serotypes responding to these 4 criteria: a serotype-specific IgG titer = 1µg/L (WHO threshold), a two-fold increase of this IgG titer compare to baseline before vaccination, a serotype-specific OPA =1/8, and a four-fold increase of functional antibodies compare to baseline. ;Timepoint(s) of evaluation of this end point: at 4-6 weeks after the end of the combined strategy

Secondary

MeasureTime frame
Secondary end point(s): 1-Proportion of patients having an ELISA serotype-specific IgG titer = 1µg/L (WHO threshold) and a two-fold increase of this IgG titer compared to baseline at 4 weeks after the PCV13 injection. 2-Proportion of patients having a sustainable response to vaccination defined by an ELISA serotype-specific IgG titer = 1µg/L (WHO threshold) and a two-fold increase of this IgG titer compared to baseline between 3-6 months after the PPV23 injection. 3-Proportion of patients having a sustainable response to vaccination defined by the same criteria as the primary outcome and measured between 9-12 months after the PPV23 injection. 4-Proportion of responding patients having titers of IgG, IgG2, IgM, and IgA rising significantly at 4 weeks after PCV13 injection, and 4 weeks, 3-6 months and 9-12 months after PPV23 injection. A significant increase is defined by a 4-fold increase of IgG and IgG2 titers, a 13-fold increase of IgA titers, and a 20-fold increase of IgM titers compared to baseline at inclusion. 5-To determine predictive factors for non-response to vaccination at 4weeks, and 9-12 months after PPV23 injection such as age, hematological malignancy, immune status, chemotherapy, immunotherapy. 6-Number of patients having local or general reactions to vaccination and number of invasive pneumococcal infections with a documented serotype considered as vaccination failure. 7-To assess the concordance between the reference immuno-monitoring dosage (WHO ELISA) and another kit of dosage (Vacczyme® Binding Site®). ;Timepoint(s) of evaluation of this end point: 1-at 4 weeks after the PCV13 injection. 2-3-6 months after the PPV23 injection 3-9-12 months after the PPV23 injection. 4-4weeks after PCV13, and 4 weeks, 3-6 months and 9-12 months after PPV23 injection 5-4 weeks, and 9-12 months after PPV23 injection 6-9-12 months after PPV23 injection 7-12 months after PPV23 injection
