Which vaccine considerations apply to adults with HIV infection?

• A. Live vaccines are safe in all cases.
• B. Inactivated vaccines are generally safe; avoid live vaccines in severely immunocompromised; vaccinate per guidelines after immune reconstitution.
• C. Vaccines should be avoided entirely.
• D. Only influenza vaccine is indicated.

Answer: (B)

The key idea is that vaccine choices and timing for adults with HIV depend on immune status. Inactivated vaccines are generally safe for people with HIV and provide important protection against preventable infections. Live vaccines, however, can pose a risk of causing disease in those who are severely immunocompromised, so they are avoided when immune function is significantly impaired. If a person on antiretroviral therapy shows immune reconstitution and gains higher CD4 counts, vaccines can then be given according to standard guidelines, including consideration of live vaccines when appropriate. In all cases, vaccines should follow established schedules adapted to HIV, maximizing protection while minimizing risk.
