The design of vaccines against viral disease has evolved considerably over the past 50 years. Live attenuated viruses (LAVs)—those created by passaging a virus in cultured cells—have proven to ...

With live attenuated vaccines, since the virus is weakened but not inactivated or “killed,” the virus can still replicate in the body, although much less so than a natural virus.
