Zostavax is made using a live but weakened chickenpox virus; the new vaccine, just called HZ/su for now, uses a piece of DNA from the virus and a compound called an adjuvant to boost the immune system.
Live attenuated influenza vaccine (LAIV) is a type of influenza vaccine in the form of a nasal spray that used to be recommended to prevent influenza. In June of 2016 the CDC stopped recommending the use of LAIV as its effectiveness has appeared to have decreased between 2013 and 2016. It is an attenuated vaccine, unlike most influenza vaccines, which are inactivated vaccines. LAIV is administered intranasally, while inactivated vaccines are administered by intramuscular injection. Both live attenuated and inactivated vaccines are typically trivalent.
