Primary Outcome Measures :
  1. Percentage of Participants who Develop a Booster Response to Tetanus Toxoid 4 Weeks after Vaccine Administration [ Time Frame: Week 16 ]
    Booster response is defined as: ≥4-fold increase in anti-tetanus toxoid immunoglobulin G (IgG) antibody concentration if the pre-vaccination level was >0.10 International units per milliliter (IU/mL) and ≤2.7 IU/mL; OR ≥2-fold increase in anti-tetanus toxoid IgG antibody concentration if the pre-vaccination level was >2.7 IU/mL; OR ≥4-fold increase in anti-tetanus toxoid IgG antibody concentration and a post-vaccination level ≥0.10 IU/mL if the pre-vaccination level was ≤0.10 IU/mL

  2. Percentage of Participants who have Positive Antibody Response to MCV (Group C Serum Bactericidal Antibodies) 4 Weeks after Vaccine Administration [ Time Frame: Week 16 ]
    Positive antibody response to Meningococcal (Groups A, C, Y, and W-135) Oligosaccharide Diphtheria CRM197 Conjugate Vaccine (GlaxoSmithKline) (MCV) is defined as: post-vaccination human complement serum bactericidal assay (hSBA) titer ≥4 times the lower limit of quantitation (LLOQ), if the pre-vaccination hSBA titer is less than the LLOQ; OR post-vaccination hSBA titer ≥4 times the pre-vaccination titer, if the prevaccination hSBA titer is greater than or equal to the LLOQ

Secondary Outcome Measures :
  1. Percentage of Participants Achieving an Investigator Global Assessment (IGA) Score of 0 or 1 and a Reduction of ≥2 Points from Baseline [ Time Frame: Week 16 ]
    The IGA measures the investigator's global assessment of the participants overall severity of their atopic dermatitis (AD), based on a static, numeric 5-point scale from 0 (clear skin) to 4 (severe disease). The score is based on an overall assessment of the degree of erythema, papulation/induration, oozing/crusting, and lichenification.

  2. Percentage of Participants Achieving a ≥75% Reduction from Baseline in Eczema Area and Severity Index Score (EASI-75) [ Time Frame: Week 16 ]
    The EASI-75 is defined as a ≥ 75% improvement from baseline in the EASI score and ranges from 0 - 72 (severe).

  3. Percentage of Participants Achieving EASI-90 [ Time Frame: Week 16 ]
    The EASI-90 is defined as a ≥ 90% improvement from baseline in the EASI score and ranges from 0 - 72 (severe).

  4. Percentage of Participants Achieving ≥4-Point Improvement from Baseline in Pruritus Numeric Rating Scale (NRS) Score [ Time Frame: Week 16 ]
    Participants will assess pruritus using a Pruritus NRS. The Pruritus NRS is an 11-point scale used by participants to rate their worst itch severity over the past 24 hours, with 0 indicating "No itch" and 10 indicating "Worst itch imaginable."

  5. Change from Baseline in Percent Body Surface Area (BSA) [ Time Frame: Baseline, Week 16 ]
    The BSA assessment estimates the extent of disease or skin involvement with respect to AD and is expressed as a percentage of total body surface.

  6. Change from Baseline in Sleep-Loss Score [ Time Frame: Baseline, Week 16 ]
    Participants will assess their Sleep-Loss due to pruritus. They will rate their sleep based on a 5-point Likert scale: 0 (not at all) to 4 (unable to sleep at all).
