First and second dose antibody responses to pneumococcal polysaccharide vaccine in infants. 1986

M Koskela, and M Leinonen, and V M Häivä, and M Timonen, and P H Mäkelä

Total (radioimmunoassay) and immunoglobulin class-specific (enzyme-linked immunosorbent assay) antibody responses to pneumococcal capsular polysaccharides were measured in children who received the first dose of 14-valent pneumococcal or control (saline) vaccine at the age of 7 months and the second dose at the age of 13 months. Types 3 and 18C elicited strong antibody responses and types 14 and 19F elicited intermediate responses in all immunoglobulin classes after both doses of the vaccine. The generally poor immunogen types 6A and 23F elicited a weak antibody response mainly in the immunoglobulin M class. The antibody levels to most pneumococcal types also decreased rapidly after both injections of the vaccine.

UI	MeSH Term	Description	Entries
D007075	Immunoglobulin M	A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin.	Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM

D007156	Immunologic Memory	The altered state of immunologic responsiveness resulting from initial contact with antigen, which enables the individual to produce antibodies more rapidly and in greater quantity in response to secondary antigenic stimulus.

D011135	Polysaccharides, Bacterial	Polysaccharides found in bacteria and in capsules thereof.	Bacterial Polysaccharides
D011863	Radioimmunoassay	Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.	Radioimmunoassays
D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D000367	Age Factors	Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
