Question

which of the following vaccines is recommended for patients who are 50 years of age or older, or adults aged 19 years or older who are immunocompromised?
adenovirus
influenza
herpes zoster
meningococcal

Explanation:

The herpes zoster vaccine is recommended for patients 50 years of age or older and for immunocompromised adults aged 19 years or older. Adenovirus vaccines are used for various purposes not specific to this age - immunocompromised criteria. Influenza vaccines are recommended annually for a wide range of people but not specifically defined by these age - immunocompromised parameters as the main indication. Meningococcal vaccines are mainly for preventing meningococcal disease and not for this specific age - immunocompromised group for this particular reason.

Answer:

Herpes zoster
