Question 5

vaccine

Answer 5

When choosing an antigen for vaccine production, there are two aspects to consider: immunogenicity and toxicity. S1 has the ADP ribosyl transferase activity responsible for toxicity of PTx and therefore is least suitable for vaccine production

-You don’t want your vaccine to be toxic, so the toxic subunit (S1) would be the least suitable one for vaccine production.

something that enters the membrane is very toxic, and you do not want vaccines to be toxic
