Vaccination considerations in immunocompromised patients and which vaccines are generally contraindicated?

• A. Live vaccines are generally contraindicated; prefer inactivated vaccines; schedule vaccines with consideration of immune status and plan
• B. Inactivated vaccines are contraindicated
• C. Live vaccines are preferred
• D. Vaccination is contraindicated entirely

Answer: (A)

In immunocompromised patients, safety hinges on whether a vaccine contains a live, replicating organism. Live attenuated vaccines can cause disease in someone with a weakened immune system, so they are generally avoided in this group. Inactivated vaccines do not replicate, so they are safe to give and are the preferred option to provide protection, though the immune response may be weaker and timing may need adjustment. Because immune status can change with treatments or recovery, vaccination should be planned around current immune function and the level of immunosuppression, sometimes delaying or spacing vaccines until reconstitution occurs. This is why the best approach is to use inactivated vaccines when possible and schedule them with consideration of immune status. The other statements are not correct because inactivated vaccines are not contraindicated, live vaccines are not preferred, and vaccination is not entirely contraindicated.
