A community health nurse is providing education to a group of older adults about immunizations. Which of the following immunizations should the nurse recommend?

The herpes zoster (shingles) vaccine is specifically recommended for adults aged 50 years and older by the CDC Advisory Committee on Immunization Practices. In older adults, the varicella-zoster virus can reactivate due to age-related decline in cell-mediated immunity, causing shingles, which can lead to painful post-herpetic neuralgia. The recombinant zoster vaccine (Shingrix) is more than 90% effective at preventing shingles and its complications. The human papillomavirus vaccine is recommended for individuals up to age 26 and in some cases up to 45, but it is not indicated for a general older adult population because HPV-related cancer prevention benefit is greatest when given before likely exposure. Rotavirus vaccine is only indicated for infants under eight months of age and has no role in older adult vaccination. The DTaP formulation is specifically for children; adults and older adults receive the Tdap (tetanus, diphtheria, acellular pertussis) booster, not DTaP. Therefore, herpes zoster vaccination is the correct and evidence-based recommendation for a group of older adults attending a community health immunization education session.
