If previously vaccinated w/ >1 dose of pneumococcal 7-valent conjugate vaccine, then at least 8 wk should elapse before vaccination. Infant & toddler Vaccination schedule: 1st dose at 2 mth (dose may be given as early as 6 wk); 2nd dose at 4 mth & 3rd dose at 6 mth (dosing interval of 4-8 wk); 4th dose at approx 12-15 mth & at least 2 mth after 3rd dose.

Thrombocytopenia or any coagulation disorder, or to those receiving anticoagulant therapy. Individuals in specific immunocompromised groups (eg, malignancy or nephrotic syndrome). Vaccination should be considered on an individual basis. Childn >24 mth w/ sickle cell disease, asplenia, HIV infection, chronic illness, or who are otherwise immunocompromised.

Elicits antibodies in response to antigenic stimulation Capsular polysaccharide vaccine against 13 strains of pneumococci, conjugated to nontoxic diphtheria protein Pneumococcal Conjugate Vaccine, 13-Valent (adsorbed) (Prevenar 13) contains the 7 pneumococcal capsular polysaccharides that are in pneumococcal 7-valent conjugate vaccine (4, 6B, 9V, 14, 18C, 19F, 23F) plus 6 additional polysaccharides (1, 3, 5, 6A, 7F, 19A) all conjugated to CRM197 carrier protein. B cells produce antibodies in response to antigenic stimulation via T-dependent and T-independent mechanisms. The immune response to most antigens is T-dependent and involves the collaboration of CD4+ T cells and B cells, recognizing the antigen in a linked fashion. CD4+ T cells (T-helper cells) provide signals to B-cells directly through cell surface protein interactions, and indirectly through the release of cytokines. These signals result in proliferation and differentiation of the B cells, and production of high-affinity antibodies. CD4+ T cell signaling is a requisite for the generation of long-lived B cells called plasma cells, which continuously produce antibodies of several isotypes (with an IgG component) and memory B cells that rapidly mobilize and secrete antibodies upon re-exposure to the same antigen. Bacterial capsular polysaccharides (PSs), while varied in chemical structure, share the common immunological property of being largely T-independent antigens. In the absence of T-cell help, PS-stimulated B-cells predominantly produce IgM antibodies; there is generally no affinity maturation of the antibodies, and no memory B-cells are generated. As vaccines, PSs are associated with poor or absent immunogenicity in infants less than 24 months of age and failure to induce immunological memory at any age. Conjugation of PSs to a protein carrier overcomes the T-cell-independent nature of PS antigens. Protein carrier-specific T cells provide the signals needed for maturation of the B cell response and generation of B cell memory. Conversion of Streptococcus pneumoniae PSs to a T-cell dependent antigen by covalent coupling to the immunogenic protein carrier CRM197 enhances the antibody response and induces immune memory. This has been demonstrated to elicit booster responses on re-exposure in infants and young children to pneumococcal polysaccharides.
