Eligibility Criteria:
Inclusion Criteria:~* Subjects who, in the opinion of the investigator, can and will comply with the requirements of the protocol (e.g. completion of the diary cards, return for follow-up visits).~* A male or female aged 50 years or above at the time of the first vaccination at risk for complications from influenza and/or pneumococcal infections, meeting their respective countries' recommendations for vaccination against influenza and pneumococcal disease.~  * At risk subjects include adults with chronic respiratory, heart, kidney, liver or neurological disease; human immunodeficiency virus (HIV) disease on combination antiretroviral therapy (cART) with cluster of differentiation 4 (CD4) T-cell counts greater than 350 cells/mm3; sickle cell disease or coeliac syndrome that may lead to splenic dysfunction (all other asplenics are excluded). The decision to enrol should be based on the investigators clinical judgement.~* Written informed consent obtained from the subject.~* Female subjects of non-childbearing potential may be enrolled in the study.~  * Non-childbearing potential is defined as pre-menarche, current tubal ligation, hysterectomy, ovariectomy or post-menopause.~* Female subjects of childbearing potential may be enrolled in the study, if the subject:~  * has practiced adequate contraception for 30 days prior to vaccination, and~ * has a negative pregnancy test on the day of vaccination, and~ * has agreed to continue adequate contraception during the entire treatment period and for 2 months after completion of the vaccination series.~Exclusion Criteria:~* Use of any investigational or non-registered product other than the study vaccines within 30 days preceding the first dose of study vaccine, or planned use during the study period.~* Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose. Inhaled, topical and low-dose intra-articular steroids are allowed.~* Planned administration/administration of a vaccine not foreseen by the study protocol within the period starting 30 days before the first dose and 30 days after the last dose of vaccine.~* Administration of such a vaccine has to be documented in the Concomitant vaccination of the electronic Case Report Form (eCRF).~* Administration of long-acting immune-modifying drugs/treatment within six months prior to the first vaccine dose or expected administration at any time during the study period. These immunosuppressant drugs/treatment/Biologics include:~  * Methotrexate~ * Leflunomide~ * Azathioprine and 6-mercaptopurine~ * Cyclosporin A~ * Cyclophosphamide~ * Tacrolimus, everolimus, sirolimus, temsirolimus~ * Mycophenolate mofetil~ * Antilymfocytaire immunoglobulins~ * Tumor Necrosis Factor (TNF) inhibitors: Adalimumab (Humira®), certolizumab (Cimzia®), etanercept (Enbrel®), golimumab (Simponi®) and infliximab(Remicade®)~ * Monoclonal antibodies and other biologicals: Rituximab (Mabthera®), Abatacept (Orencia®), tocilizumab (RoActemra®), basiliximab (Simulect®), Natalizumab (Tysabri®) cluster of differentiation 3 (CD3), ...~ * Antitumor agents: alkylating agents, antimetabolites, antitumor antibiotics, topoisomerase inhibitors, microtubule inhibitors and other anti-tumor agents~ * Lenalidomide Revlimid®~ * Tasonermin: Beromun®~ * Proleukin® (aldesleukin; Novartis, ...)~ * Tyrosine kinase inhibitor (Glivec®)Omalizumab Xolair®~ * Eculizumab Soliris® The above list is compiled from: \[Federal Public Service Belgium: Health, Food Chain Safety and Environment\].~ * Any immunosuppressive treatment which in the opinion of the investigator will not allow an adequate immune response. Inhaled, topical and low-dose intra-articular steroids are allowed.~* Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational vaccine/product.~* Previous vaccination with a pneumococcal vaccine within the last five years.~* Previous vaccination with an influenza vaccine within the last six months.~* Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination. HIV infected subjects on cART with CD4 T-cell counts above 350 cells/mm3 can be enrolled.~* History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccines.~* Acute disease and/or fever at the time of enrolment.~  * Fever is defined as temperature ≥ 38.0°C (100.4°F). The preferred route for recording temperature in this study will be axillary.~ * Subjects with a minor illness (such as mild diarrhoea, mild upper respiratory infection) without fever \[≥ 38.0°C (100.4°F)\] may be enrolled at the discretion of the investigator.~* Administration of immunoglobulins and/or any blood products within the three months preceding the first dose of study vaccine or planned administration during the study period.~* Pregnant or lactating female.~* Female planning to become pregnant or planning to discontinue contraceptive precautions.~* Any condition which, in the opinion of the investigator, prevents the subject from participating in the study or would make intramuscular (IM) injection unsafe.~* Asplenia or dysfunction of the spleen. This excludes homozygous sickle cell disease or coeliac syndrome that may lead to splenic dysfunction.~* Acute clinically significant (i.e. a medically significant change from baseline condition in the past 30 days) pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests.~* History of chronic alcohol consumption and/or drug abuse.~* History of Guillain-Barré syndrome.~* A history of anaphylaxis following ANY vaccination.
