CD79A and amyotrophic lateral sclerosis: Analysis of ALS specimens in children aged 24–59 months (excluding the three children who received the full vaccine dose) showed that two immunisations with ETVAX alone (quarter or half dose) or half doses with different doses of dmLT elicited high and significant (ie, at least two-times increase versus baseline) IgA responses against all four vaccine colonisation factors and LTB, as measured 7 days after the first dose or 5 days after the second dose; few responses were observed in placebo recipients (appendix p 10).
