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.
The Arilvax vaccine is made from a live attenuated form of the yellow fever virus, strain 17D. In the United States, the vaccine is given only at Yellow Fever Vaccination Centers authorized by the U.S. Public Health Service. About 95% of vaccine recipients acquire long-term immunity to the yellow fever virus.
