Regarding recombinant vaccines, it is INCORRECT to state that: (Only one statement corresponds to the answer) * (a) They are free from infectious viral particles, which increases safety in production and use (b) The development of recombinant vaccines is generally faster than conventional vaccines from inactivated or attenuated pathogens (c) Expansion of production scale is easier than conventional vaccines, since they are produced using fermentation methods in bioreactors (d) The development of recombinant vaccines depends on industrial cultivation methods of the pathogen of interest (e) Recombinant vaccines can be produced on different platforms, such as animal and microorganism cells
