Vaccination in children living with HIV – review of Polish recommendations

Abstract

Vaccines are an extremely effective primary prevention tool recommended for routine use in children worldwide. Vaccination is crucial for patients with underlying diseases, including children living with HIV, because of their increased risk of morbidity and mortality from various vaccine-preventable diseases. Complex care for patients living with HIV includes antiretroviral therapy (which has dramatically improved survival), prophylaxis and treatment of common infections, prophylaxis and treatment of opportunistic infections, and vaccination. Immunisation is generally safe and beneficial for children living with HIV, although HIV-induced immune suppression reduces the benefits. All inactivated vaccines, whether killed whole organism or subunit, recombinant, toxoid, polysaccharide or conjugate (which includes diphtheria, tetanus, pertussis, poliomyelitis, Haemophilus influenzae type b, hepatitis B, hepatitis A, Streptococcus pneumoniae vaccines, Neisseria meningitidis, influenza, HPV), can be administered safely. Live attenuated measles–mumps–rubella and varicella vaccines are indicated in children without severe immunodeficiency. The Bacillus Calmette–Guérin vaccine is contraindicated due to the risk of disseminated BCG infection. Although a live attenuated influenza vaccine is available, it is contraindicated for people living with HIV because of the paucity of safety data and the availability of alternative vaccines. The study reviews the current paediatric immunisation recommendations in HIV infection in Poland. Additionally, we focus on vaccine effectiveness, especially HBV protection based on anti-Hbs antibodies.
