Please help? Is the shingles vaccine a one time shot or must you have one each year to be protected?

In brief: NoClinicalTrial Data

Good question but no clinical trial data exists.
Merck, who did all the work to develop the vaccine, did the only clinical trial to date which compared incidence of shingles in people who received real vaccine vs. Just a saline placebo injection. Study: http://www.Merck.Com/product/usa/pi_circulars/z/zostavax/zostavax_pi2.Pdf.
