CD79A and amyotrophic lateral sclerosis: While a vaccine dose-dependent increase was seen in IgA-ALS responses, but not in IgG responses, particularly to IVP and IpaB in WRSs2 vaccinees and to IVP in WRSs3 vaccines, in both groups of vaccinees, the magnitude of the IgA and IgG responses to all 3 antigens were highest at the 107 CFU dose (Fig 1 and Table 1). There were more subjects in the WRSs2-vaccinated group with an IgG response to all 3 antigens as compared to the WRSs3 group, although the magnitude of the IgG-ALS response was similar for both vaccine candidates (Fig 1 and Table 1).
