The Vaccine to Haemophilus Influenzae Type B Is Called a Conjugate

The vaccine to Haemophilus influenzae type b is called a conjugate vaccine. It is composed of the tetanus toxoid protein conjugated to the capsular polysaccharide of the H. influenzae type b bacteria. When used to vaccinate infants, the antibody response generated by this vaccine would include:

A) Antibodies to the bacterial polysaccharide and the tetanus toxoid
B) Antibodies to the tetanus toxoid only
C) Antibodies to the bacterial polysaccharide only
D) Antibodies that only bind to the protein-polysaccharide conjugate in the vaccine
E) Antibodies that recognize the polysaccharide capsule when shed by the bacteria
