Immunizations for the immunocompromised child
1Children's Hospital Immunodeficiency Program, University of Colorado Health Sciences Center, Denver 80262, USA.
Insights
Immunocompromised children benefit from inactivated vaccines, including pneumococcal and influenza. Live vaccines are generally avoided, except for the measles, mumps, and rubella (MMR) vaccine in certain HIV-infected children.
Area of Science:
- Pediatric Immunology
- Vaccinology
- Infectious Diseases
Background:
- Immunocompromised children often have suboptimal immune responses to vaccinations.
- Determining appropriate vaccination strategies is crucial for preventing infections in this vulnerable population.
Purpose of the Study:
- To outline recommended immunization guidelines for immunocompromised children.
- To specify which vaccines are safe and beneficial for this group.
Main Methods:
- Review of current vaccination recommendations for immunocompromised pediatric populations.
- Analysis of contraindications and specific considerations for live vaccines.
Main Results:
- Inactivated vaccines, pneumococcal, and influenza immunizations are recommended.
- Live viral and bacterial vaccines are generally contraindicated, with exceptions for the measles, mumps, and rubella (MMR) vaccine in specific human immunodeficiency virus (HIV)-infected children without severe immunosuppression.
- An accelerated MMR schedule is recommended for HIV-infected children.
Conclusions:
- Specific vaccination protocols are necessary for immunocompromised children to maximize protection.
- Careful consideration of vaccine type, timing, and patient immune status is essential.
Abstract:
Although immunocompromised children are unlikely to have optimal immune responses to vaccines, some will benefit from immunization. They should receive inactivated vaccines that are routinely recommended for immunocompetent children plus pneumococcal and influenza immunizations. Live viral and bacterial vaccines are contraindicated with the exception of MMR. It may be given to children infected with HIV who do not have severe immunosuppression. The timing of immunizations is generally the same for immunocompromised and normal children. However, the MMR schedule in children infected with HIV is accelerated, with 2 doses given 1 month apart. Susceptible children whose immunosuppression is related to a temporary condition should be vaccinated after immune dysfunction has resolved. The question of revacination for children infected with HIV who are receiving effective antiretroviral therapy is under investigation, but no specific recommendations are currently available.
