Question: 

Is the Shingles vaccine only once, or do you have to get re-immunized? And if so, how often is immunization required ? Thanks

Answer: 

There is currently no recommendation for booster doses of the shingles vaccine (only one dose of the vaccine is currently recommended). The efficacy of protection has not been assessed beyond 7 years and it is not known if booster doses of vaccine are beneficial. This is an area of ongoing research. 

You can discuss this further with your health care provider.
