For the successful development of a vaccine to be used against a pathogen, it is necessary that:

1) The surface antigens of the pathogen not change.
2) A rearrangement of the B cell receptor antibodies takes place.
3) All of the surface antigens on the pathogen be identified.
4) The pathogen has only one epitope.

Final answer:

For the successful development of a vaccine against a pathogen, it is necessary that the surface antigens of the pathogen do not change, B cells rearrange their receptor antibodies, and all surface antigens on the pathogen are identified.

Explanation:

The successful development of a vaccine against a pathogen requires several factors:

The surface antigens of the pathogen should not change, as vaccines target specific antigens to elicit an immune response.
The B cells must rearrange their receptor antibodies in order to recognize and bind to the pathogen's antigens, which initiates the production of antibodies.
All of the surface antigens on the pathogen must be identified to ensure that the vaccine targets the most relevant antigens.

It is important to note that the pathogen does not need to have only one epitope, as vaccines can target multiple antigens to provide broader protection. Additionally, the heterozygosity of MHC molecules is not a requirement for successful vaccine development.
