CDC recommends that people 60 years old and older get shingles vaccine to prevent shingles and PHN. Shingles vaccine has been used since 2006. ZostavaxÂ® is the only shingles vaccine currently approved for use in the United States. 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 doctorâs office or pharmacy.
The Food and Drug Administration has approved the use of the varicella-zoster vaccine (Zostavax) for adults age 50 and older. Like the chickenpox vaccine, the shingles vaccine doesn't guarantee you won't get shingles. But this vaccine will likely reduce the course and severity of the disease and reduce your risk of postherpetic neuralgia. The shingles vaccine is used only as a prevention strategy, however. It's not intended to treat people who currently have the disease. The vaccine contains live virus and should not be given to people who have weakened immune systems.
