Botulinum antitoxins and antibacterial IgM and IgG antibodies in sera of persons immunized with botulinum polytoxoid combined with cholera vaccine. II. Response to cholera vaccine.


The response of humans to cholera vaccine was very heterogeneous. The proportion of IgG vibriocidal antibodies was high in persons having previous natural or artificial contact with V. cholerae antigens. Predominance of IgM antibody response was seen in persons vaccinated for the first time. This type of response was sometimes evoked by unspecific stimuli such as botulinum polytoxoid without cholera vaccine. Antibodies passively protecting mice were found both in IgM and IgG globulins but the activity of these antibodies was higher in IgG than in IgM globulins.
