  IMMUNOGENICITY OF FDA DTP VERSUS WHO DTP   (Site not responding. Last check: 2007-11-05)
It is possible that the response after the third dose was enhanced because children were primed with a lower dose in the FDA group, or perhaps was a reflection of the quality of the antigen which can evoke a strong priming and a good immunological memory.
A study which was done in Australia showed that the increase in diphtheria or tetanus concentration was not associated with an increase in the reported systemic or local clinical signs associated with the first three doses.
Immunogenicity of tetanus and diphtheria did not correlate with the antigen dose contained in the vaccine.

For infants, the immunogenicity of PRP-OMP (which has a carrier derived from the meningococcal outer membrane protein) appears to be unaffected by the absence of prior or concurrent DTP vaccination (24).
Immunogenicity studies among infants who received TETRAMUNETM at ages 2, 4, and 6 months (37, Lederle Laboratories/Praxis Biologics, unpublished data) indicated that antibody responses to Hib PRP, diphtheria, and tetanus toxins were comparable to or higher than those in persons who received separate, but concurrent administration of DTP and HbOC vaccines.
Hib vaccine is immunogenic in patients with increased risk for invasive disease, such as those with sickle-cell disease (46), leukemia (47), human immunodeficiency virus (HIV) infection (48,49), and in those who have had splenectomies (50).

After demonstration of safety, immunogenicity, and induction of serum bactericidal activity, an efficacy of 90% (95% confidence interval (CI) = 50%-95%) was shown for one dose of vaccine given to children 18-71 months old in a large trial in Finland.
A subsequent immunogenicity study documented antibody responses that were similar to those in the Alaskan and Finnish efficacy trials ( Table_2).
Studies suggest, however, good immunogenicity in patients with sickle cell disease (15), leukemia (16), patients who have had splenectomies (17) or who have HIV infection (18,19), and administering vaccine to these patients is not contraindicated.

 Hepatitis Central, Safety and Immunogenicity of Hepatitis A Vaccine in Patients With Chronic Liver Disease
A secondary objective was to compare the safety of the hepatitis A vaccine with that of a commercial hepatitis B vaccine in subjects with chronic hepatitis C. A total of 475 subjects over the age of 18 years were enrolled into 1 of 5 groups according to history, serological data, and previous diagnosis.
The vaccine has, however, been shown to be immunogenic for at least 2 years and to be well tolerated in adults and children with hemophilia when administered subcutaneously (to reduce risk of hematoma).
Thus, a study was undertaken to evaluate the safety and immunogenicity of an inactivated hepatitis A vaccine in patients with chronic hepatitis B and C and with CLD of other etiologies compared with a control group of healthy adults.

Nevertheless, research into the immunogenicity of early vaccination (begun during the first few days of life) of preterm NB has been inconclusive with disagreement between the various studies available in published literature.
The first implication, pointed out by Sadeck and Ramos in the conclusions of their article, is the need for serological tests after the original three-dose vaccination when the preterm NB has been vaccinated during the first week of life because of the possibility that the child will need booster doses to achieve satisfactory anti-HBs antibodies.

 Gerd Ritter
For therapeutic application, the immunogenicity of the injected antibody is of paramount importance.
For example, mouse-derived monoclonal antibodies are highly immunogenic in humans and generally can be given only for a limited period of time before onset of a human anti-mouse Ig response (HAMA), which rapidly clears the murine antibody from the blood and may trigger anaphylactic reactions.
To attenuate or abolish immunogenicity and to allow long-term treatment of patients without the interference of an anti-immunoglobulin response, various molecular technologies have been employed that reduce the amount of foreign Ig residues in a therapeutic antibody, a factor hypothesized to inversely correlate with the immunogenicity of an antibody.

Biopharmaceutical immunogenicity: association between epoetin alfa and pure red cell aplasia This short review discusses the possible reasons for the recent upsurge in cases of pure red cell aplasia in chronic kidney disease patients treated with epoetin alfa.
The increase in suspected cases of epoetin-associated PRCA coincided with the removal of human serum albumin from the epoetin alfa formulation and its replacement with polysorbate 80 and glycine as stabilisers.
The majority of recorded cases of antibody-mediated PRCA occurred in patients receiving epoetin alfa by the subcutaneous route and, in Europe, use of epoetin alfa is now restricted to the intravenous route in renal patients.

In addition to the need for inclusion of helper epitopes, the intrinsically low immunogenicity of peptides requires that they be administered with strong adjuvants to enhance and/or modulate the nature of the response generated.

We are interested in the epitope modification of intact proteins as a method to enhance their immunogenicity for the generation of recombinant protein-based vaccines.
Consistent with this general understanding of the induction of antibody responses to protein immunogens, good antibody responses to synthetic peptide-epitope constructs have been shown to depend on the presence, orientation, and multiplicity of the T cell epitope in the construct [ 7-11 ].
