    • A dry powder norovirus vaccine is provided, which comprises at least two norovirus antigens representing different genogroups. The vaccine may be produced by formulation with a mixture of different antigens or combination of monovalent powders with each containing one antigen. The formulated vaccine is suitable for mucosal administration and soluble in aqueous solutions for parenteral administration. A method of immunization is also provided, which comprises at least one administration of the vaccine via mucosal and/or parental route. The immunization may have multiple administrations of the vaccine, i.e., one or more immunizations via a mucosal route followed by one or more immunizations via a parenteral route or vice versa, to maximize both mucosal and systemic immune responses and protection against norovirus infections.
    • 提供一种干粉诺如病毒疫苗,其包含至少两种代表不同基因组的诺如病毒抗原。 疫苗可以通过用不同抗原或单价粉末的混合物与每种含有一种抗原的混合物制剂来制备。 配制的疫苗适用于粘膜给药,可溶于非肠道给药的水溶液。 还提供免疫方法,其包括通过粘膜和/或亲本途径至少一次给予疫苗。 免疫可以具有疫苗的多次施用,即通过粘膜途径进行一次或多次免疫,随后通过肠胃外途径进行一次或多次免疫,反之亦然,以最大限度地提高粘膜和全身免疫应答并防止诺如病毒感染。
