Zostavax is a live attenuated virus vaccine used to protect from herpes zoster, more commonly known as the shingles virus. Zostavax was developed and produced by the New Jersey pharmaceutical company Merck & Co, one of the world’s largest vaccine manufacturers. It is used in individuals 60 years of age and older.
Zostavax was approved and licensed by the U.S. Food and Drug Administration (FDA) in May 2006. Later, in 2011 FDA approved the live vaccine for use in individuals aged between 50 to 59 years of age. The Advisory Committee on Immunization Practices (ACIP) in June 2011, the vaccine for adults aged 50 through 59 years was refused and reaffirmed the recommendation for adults aged 60 years and older. Later, the FDA approved the expanded indication for Zostavax in March 2011 for adults aged 50 through 59 years.
