“…Hence, insufficient neutralization of the locally produced PT in mucosal tissue may support the establishment of long-term bacterial colonization. This hypothesis can now be tested with a reformulated aP vaccine containing the genetically detoxified gdPT antigen with superior protective immunogenicity, which has a preserved tertiary structure with fully preserved conformational neutralizing epitopes [62][63][64][65].…”

“…Data from individual animals (e.g., Y5) suggest that a titer >1 g/ml hu1B7 is required for protection in this model and that this titer needs to be maintained until the infant's immune system supplies a similar level of neutralizing anti-PTx antibodies. Human clinical data have demonstrated a correlation between the dose and detoxification method of PTx in a vaccine formulation and subsequent postvaccination anti-PTx titers, with the Danish high dose PTx only (14) and genetically inactivated PTx (PTg) (39) conferring the highest and most durable responses. Moreover, prior data from us and others demonstrated that PTg preserves the hu1B7 epitope and induces higher titers of hu1B7-like neutralizing antibodies than chemically detoxified PTx (40,41).…”

“…Hier ist es besonders bemerkenswert, dass ein in Studien untersuchter Pertussis-Einzelimpfstoff mit genetisch hergestellten PT eine deutlich bessere Immunogenität aufweist als azelluläre Impfstoffe, die natürliches, aber chemisch detoxifiziertes PT neben weiteren Bestandteilen, wie z. B. FHA und Fimbrien, enthalten [12]. Daraus kann man schließen, dass das chemisch detoxifizierte PT offensichtlich deutlich weniger immunogen als das genetisch hergestellte PT ist.…”

“…Daraus kann man schließen, dass das chemisch detoxifizierte PT offensichtlich deutlich weniger immunogen als das genetisch hergestellte PT ist. Ob die bessere Immunogenität auch mit einer besseren (Langzeit-) Wirksamkeit korreliert, muss in weiteren Studien geklärt werden [12].…”
