With respect to recombinant vaccines, it is CORRECT to state that: * (Only one statement is correct) (a) Protein subunit vaccines are formulated with the expression vector encoding the immunogenic protein or protein fragment (b) Recombinant carrier organisms are genetically modified to contain the pathogenic protein of the organism that will be the target of the vaccine (c) Nucleic acid vaccines are formulated with DNA or RNA molecules that, once internalized by cells, will generate recombinant proteins that will trigger the immune response against the desired pathogen (d) Unlike DNA vaccines, mRNA vaccines do not need to be internalized by cells, being recognized as foreign molecules to the organism that received them. (e) Laboratory-produced phages can be used as delivery tools in DNA vaccines, which will allow the expression of immunogenic proteins to the organism that received them (f) Pseudoviral particles (VLPs) are produced in cells that receive expression vectors containing the information for the synthesis of structural proteins and responsible for replicating the genome of the target virus
