Live Vaccines for Immunocompetent and Immunocompromised Individuals

Introduction to Live Vaccines

The American Academy of Allergy, Asthma, and Immunology recommends the use of live vaccines, including MMR, varicella, MMRV, herpes zoster, rotavirus, LAIV, yellow fever, oral typhoid, BCG, and vaccinia, for immunocompetent individuals and certain immunocompromised patients 1, 2, 3

The Centers for Disease Control and Prevention (CDC) recommends MMR vaccine for immunocompetent individuals and HIV-infected patients with adequate CD4 counts (≥200 cells/mm³ in adults or ≥15% in children) 1, 4
The CDC recommends varicella vaccine for HIV-infected patients when adults have CD4 count ≥200 cells/mm³ and children aged 1-13 years have CD4 percentage ≥15% 1, 4
The CDC recommends MMRV vaccine as a combined vaccine containing all four antigens in a single formulation 1, 3
The CDC recommends herpes zoster vaccine (Zostavax) for prevention of shingles in immunocompetent individuals 1, 3
The CDC recommends rotavirus vaccine for infants to prevent severe rotavirus gastroenteritis, contraindicated in severe combined immunodeficiency 1, 3
The CDC recommends LAIV for healthy people aged 2-49 years, absolutely contraindicated in immunocompromised patients 1, 4
The World Health Organization (WHO) recommends yellow fever vaccine for travel to endemic areas, contraindicated in severely immunocompromised patients 1, 5

The CDC recommends BCG vaccine for tuberculosis prevention, contraindicated in patients with severe T-cell immunodeficiencies and those with IFN-γ-IL-12 pathway defects who have predilection for BCG-induced infection 1, 6
The CDC recommends oral typhoid vaccine (Ty21a) for typhoid fever prevention, contraindicated in severe antibody deficiencies and T-cell defects 1, 5

The CDC states that absolute contraindications exist for patients with severe combined immunodeficiency (SCID), complete DiGeorge syndrome, and severe antibody deficiencies (X-linked agammaglobulinemia, common variable immunodeficiency) where all live vaccines must be avoided 1, 6
The Infectious Diseases Society of America recommends that patients with phagocytic function disorders (chronic granulomatous disease, leukocyte adhesion defects, myeloperoxidase deficiency) should avoid live bacterial vaccines but can receive live viral vaccines 1, 5

The CDC recommends that household members of immunocompromised patients should receive all age-appropriate vaccines, including MMR, varicella, rotavirus (for infants), and zoster vaccines, to create a protective barrier 3, 4
The CDC states that both inactivated influenza vaccine (IIV) and LAIV are acceptable for household contacts, as transmission of LAIV virus to immunocompromised individuals is extremely rare 6, 4
