3) Which of the following statements is false regarding polysaccharide and conjugated vaccines? O Polysaccharide vaccines stimulate B cell or humoral responses only, reserving their use for patients over 2 years of age. O Conjugated vaccines can be used in children as young as 2 months of age because they stimulate both B cell and T helper cell immune responses. O Conjugated vaccines link a polysaccharide to a protein that stimulates a wider immune response. O Polysaccharide vaccines use carbohydrates found in the external capsule of the bacteria as antigens O The conjugate protein used, such as diphtheria, can also provide adequate protection against itself in addition to the polysaccharide
