4) According to the passage, which of the following is true?
A. To optimize the potential biological dangers associated with traditional inactivated or killed vaccines, the development of safer but less potent recombinant vaccines is spurring required protective activities.
research to improve their immunogenic and B. Most non-living vaccines need a "danger" signal in the form of an adjuvant to get the innate immune system and, later, the adaptive immune system to react strongly enough.
C. None of the successful vaccines have been made by trial and error.
