Methods: ShigETEC was evaluated in a two-staged, randomized, double-blind and placebo-controlled Phase I clinical trial. A live attenuated non-invasive Shigella vaccine strain lacking LPS O-antigen and expressing the ETEC toxoids, named ShigETEC was characterized previously in non-clinical studies. and enterotoxigenic Escherichia coli (ETEC) cause high morbidity and mortality worldwide, yet no licensed vaccines are available to prevent corresponding infections. Vaccine shots in S1PR-modulator treated pwMS ahead of schedule may be a strategy to overcome insufficient humoral immune responses following the standard vaccination scheme.īackground: Shigella spp. We conclude that the humoral immune response may reach protective levels after the third preferred dose of the homologous SARS-CoV-2 mRNA vaccine. After the third vaccination, we found clinically relevant IgG titers in four out of eight individuals (50%). An antibody titer of 100 AU/mL or more was considered protective.

We quantified the serum levels of IgG antibodies against the receptor-binding domain of SARS-CoV-2 four weeks later. Eight pwMS that were treated with fingolimod received a third homologous SARS-CoV-2 mRNA vaccine dose, either the Moderna’s mRNA-1273 or Pfizer-BioNTech’s BNT162b2 vaccine. We studied the extent of the humoral immune response after the preferred third mRNA SARS-CoV-2 vaccine in S1PR-modulator treated people with MS (pwMS) and insufficient IgG responses after the standard immunization scheme.

We discuss some of the major determinants of the introduction of Shigella vaccines and the importance of developing a succinct, compelling public health value proposition. There is thus no guarantee that a Shigella vaccine would become an adoption priority by those low- and middle-income countries that could benefit the most. Nonetheless, such a vaccine would arrive in the context of increasingly crowded and costly childhood immunization programs, among a myriad of other new and improved vaccines currently or soon on the market. Several vaccine developers are in advanced clinical studies with highly promising multivalent formulations a safe and efficacious Shigella vaccine would represent a great scientific achievement. Shigella sonnei and flexneri remain among the top bacterial causes of dysentery and severe diarrhea in children.
