If a patient received dose 1 of varicella vaccine (Varivax or ProQuad, Merck) at age 60 years, should we administer zoster vaccine as dose 2?

The action taken depends on why varicella vaccine was given in the first place. If it was given because the person tested negative for varicella antibody, then the next dose should be varicella vaccine. If the varicella vaccine was given in error (i.e., without serologic testing), then Shingrix should be given.
