Abstract

Whooping cough is a respiratory illness most severe in infants and young children. While the introduction of whole-cell (wP) and acellular pertussis (aP) vaccines has greatly reduced the burden of the disease, pertussis remains a problem in neonates and adolescents. New vaccines are needed that can provide early life and long-lasting protection of infants. Vaccination at an early age, however, is problematic due to the interference with maternally derived antibodies (MatAbs) and the bias towards Th2-type responses following vaccination. Here we report the development of a novel vaccine formulation against pertussis that is highly protective in the presence of MatAbs. We co-formulated pertussis toxoid (PTd) and filamentous hemagglutinin (FHA) with cytosine-phosphate-guanosine oligodeoxynucleotides (CpG ODN), cationic innate defense regulator (IDR) peptide and polyphosphazene (PP) into microparticle and soluble vaccine formulations and tested them in murine and porcine models in the presence and absence of passive immunity. Vaccines composed of the new adjuvant formulations induced an earlier onset of immunity, higher anti-pertussis IgG2a and IgA titers, and a balanced Th1/Th2-type responses when compared to immunization with Quadracel(®), one of the commercially available vaccines for pertussis. Most importantly, the vaccines offered protection against challenge infection in the presence of passively transferred MatAbs.

摘要

百日咳是一种严重的呼吸道疾病,多见于婴幼儿。全细胞(wP)和无细胞百日咳(aP)疫苗的问世大大降低了该病的负担,但百日咳在新生儿和青少年中仍然是一个问题。需要开发新的疫苗,为婴儿提供早期和持久的保护。然而,由于疫苗接种会干扰母体来源的抗体(MatAbs),并且会偏向于接种后的 Th2 型反应,因此在早期接种疫苗存在问题。在这里,我们报告了一种针对百日咳的新型疫苗制剂的开发,该制剂在存在 MatAbs 的情况下具有高度的保护作用。我们将百日咳毒素(PTd)和丝状血凝素(FHA)与胞嘧啶-磷酸-鸟嘌呤寡脱氧核苷酸(CpG ODN)、阳离子先天防御调节剂(IDR)肽和聚磷腈(PP)共同配制入微颗粒和可溶性疫苗制剂,并在存在和不存在被动免疫的情况下在小鼠和猪模型中进行了测试。与一种商业上可用于预防百日咳的疫苗(百白破疫苗)相比,由新佐剂制剂组成的疫苗诱导更早的免疫起始、更高的抗百日咳 IgG2a 和 IgA 滴度,并产生平衡的 Th1/Th2 型反应。最重要的是,这些疫苗在存在被动转移的 MatAbs 的情况下提供了针对挑战感染的保护。
