There have been numerous lawsuits filed alleging injuries caused by the shingles vaccine Zostavax. Cases have stated they were not warned of the adverse side effects of the vaccine alleging it caused the diseases it is meant to prevent, among other things.

Here is what the CDC says to consumers: “Your risk of shingles and postherpetic neuralgia (PHN) increases as you get older. CDC recommends that people 60 years old and older get shingles vaccine (Zostavax®) to prevent shingles and PHN. Shingrix (recombinant zoster vaccine) is the preferred vaccine, over Zostavax® (zoster vaccine live), a shingles vaccine in use since 2006. Zostavax may still be used to prevent shingles in healthy adults 60 years and older. For example, you could use Zostavax if a person is allergic to Shingrix, prefers Zostavax, or requests immediate vaccination and Shingrix is unavailable. Zostavax (zoster vaccine live) was licensed by the FDA in 2006. This vaccine reduces the risk of developing shingles by 51% and PHN by 67%. It is given in one dose as a shot, and can be given in a doctor’s office or pharmacy.“
