The question asks about parenteral administration of the vaccine (meaning, not using the oral route). Non-oral vaccines will not strongly elicit IgA response. Non-oral vaccines not super helpful in combating a gut mucosal infection such as V. cholera, where IgA is more salient. Not sure if this is the actual correct reasoning, but it led to the right answer.
aesalmonI totally skipped over the word "parentally" when taking this - ugh!+22
imgdocWow, I feel like such an idiot for getting such an easy question wrong...I skipped over parenteral and starting thinking about Cholera toxin MoA. ffs...+
