[IMMUNIZATIONS IN IMMUNOCOMPROMISED HOSTS--PRINCIPLES AND UPDATED RECOMMENDATIONS]

Area of Science:

• Immunology
• Infectious Diseases
• Public Health

Context:

• Increasing prevalence of immunocompromised patients.
• Elevated risk of severe outcomes from infections in this population.
• Vaccine-preventable diseases pose significant threats.

Purpose:

• To address critical questions regarding vaccine administration in immunocompromised individuals.
• To summarize current immunization recommendations for immunocompromised patients.
• To provide information on vaccine safety, efficacy, and contraindications.

Summary:

• Live vaccines may cause adverse events in immunocompromised patients.
• Inactivated vaccines might offer reduced or shorter protection.
• Vaccination prior to immunosuppressive therapy is often preferred.
• Guidance is needed for vaccinating household contacts and immunocompromised travelers.

Impact:

• Aims to improve clinical decision-making for vaccinating at-risk populations.
• Highlights the need for more data on vaccine safety and immunogenicity in immunocompromised individuals.
• Contributes to better management of vaccine-preventable diseases in vulnerable groups.
