Vaccinations HIV patients: which statement is correct?

The key idea here is that vaccination in people with HIV depends on how strong the immune system is and whether the vaccine is live or inactivated. Live vaccines carry a risk of causing disease if the immune system is severely weakened, so they are avoided when CD4 counts are very low. Measles, mumps, and rubella (MMR) and varicella vaccines are live vaccines. When the CD4 count is 200 cells/µL or less, the immune system is considered severely compromised, making these live vaccines potentially dangerous. Therefore, giving MMR or varicella is contraindicated at or below this threshold. If CD4 counts are higher and there are no other contraindications, these vaccines can be considered with clinical judgment. Hepatitis B vaccine is recommended for people with HIV because coinfection can lead to worse outcomes, so it is not contraindicated. Influenza vaccination is also advised for individuals with HIV, using the inactivated form given annually. The statement that it should never be given is incorrect; the inactivated vaccine is appropriate, while the live intranasal form is generally avoided in immunocompromised patients. Pneumococcal vaccination is recommended due to the higher risk of pneumococcal disease in HIV, so it is not contraindicated.
