    • The present invention relates to a novel lipoprotein particle, methods for preparing and purifying the same, its use in medicine, particularly in the prevention of malarial infections, compositions/vaccines containing the particle or antibodies against the protein particle such as monoclonal or polyclonal antibodies and use of the same, particularly in therapy. Furthermore, particles with the specific ratio can be prepared by employing yeast, Saccharomyces cerevisiae or Pichia pastoris. In particular it relates to an immunogenic protein particle comprising the following monomers: a. a fusion protein comprising sequences derived from a CS protein of P. vivax and the S antigen of Hepatitis B (CSV-S), and b. S antigen derived from Hepatitis B virus, and characterized in that the ratio of S to CSV-S is in the range 0.1 to 1. Suitably, the ratio of S to CSV-S is in the range 0.19 to 0.30 or 0.68 to 0.80.
    • 本发明涉及一种新型蛋白质颗粒,其制备和纯化方法,其在医学中的用途,特别是用于预防疟疾感染的方法,含有颗粒或抗蛋白质颗粒的抗体的组合物/疫苗,如单克隆或多克隆抗体和 使用它们,特别是在治疗中。 此外,可以通过使用酵母,酿酒酵母或巴斯德毕赤酵母来制备具有特定比例的颗粒。 具体涉及包含以下单体的免疫原性蛋白质颗粒:a。 包含来自P.vivax的CS蛋白和乙型肝炎S抗原(CSV-S)的序列的融合蛋白,以及b。 S抗原来源于乙型肝炎病毒,并且其特征在于S与CSV-S的比率在0.1至1的范围内。合适地,S与CSV-S的比率在0.19至0.30或0.68至0.80的范围内。
