In this article, optimal vaccination of adult transplant recipients, including safety, efficacy, indication and timing, tuberculosis, poliomyelitis and diphtheria-tetanus in school collectivities can be rationalized

19 persons aged 19-20 years were vaccinated intradermally with 1.5 Lf diphtheria toxoid and 15 Lf tetanus toxoid (contained in 0.1 ml) by means of a single injection with a jet injector (Dermo-Jet). In cases which had not previously been immunized, vaccination with the toxoid doses employed did not induce detectable antitoxin titers. In all cases which had previously been immunized the antitoxin titers after the booster injection were at least 400 times higher than the protection threshold for diphtheria and 1700 times higher than the protection threshold for tetanus. This was also the case in preimmunized cases which had no detectable antitoxin titer before the vaccination.

The increase in antitoxin titer was inversely proportional to the prevaccinal titer in the manner of a logarithmic exponential function. It may be concluded from these results that the benefit of a booster vaccination is particularly high in poorly immunized persons whereas it is clearly limited in cases showing a high prevaccinal titer. The well tolerated intradermal vaccination with the jet injector (Dermo-Jet) can be considered as equivalent to the subcutaneous technic. From the point of view of organization (time consumption, problems of sterilization) this method is much preferable to intramuscular or subcutaneous niedrigem Diphtherietoxoidgehalt.single intraperitoneal injection of 1 mug of DNP-ovalbumin suspended with 1 mg aluminum hydroxide in 0.5 ml of saline. The formation of anti-DNP reaginic antibody was completely suppressed by treatment of mice with a conjugate consisting of the hapten coupled to an isolgous nonimmunogenic carrier, viz.

, murine phi-globulins. However,  Order now  did not affect the level of antibody formation to the carrier of the immunizing antigen. The induction of unresponsiveness was dose dependent, complete suppression being achieved with 1 mg of the tolerogen. The state of unresponsiveness could be maintained for prolonged periods (these observations were made over a period of at least 8 months) by repeated injections of the tolerogen at intervals of 2 months. More importantly, the state of unresponsiveness could be induced readily not only in normal, but also in sensitized mice, i.e., this treatment was capable of abrogating an ongoing reaginic response, and the suppression was immunologically specific.

Hence this system appears to have a great potential for adaptation to the treatment of allergic diseases in man.papillomavirus (HPV) vaccination in low-resource settings.important primary role in cervical cancer prevention once their long-term immunogenicity and safety are evaluated at the population level. The aim of this study was to optimize an assay to be used in evaluating the long-term durability of HPV vaccine response following a pilot vaccination of adolescent girls in Ghana. METHODS: A rapid, high-throughput, indirect enzyme-linked immunosorbent assay (ELISA) was optimized for the detection and quantitation of anti-HPV L1 (late expression protein: types 6, 11, 16 and 18) immunoglobulin G (IgG) in human serum (n = 89). The utility of the assay was demonstrated using serum collected from a cohort of pre-adolescent girls (n = 49) previously vaccinated with a quadrivalent vaccine and non-immune serum obtained from age-matched controls (n = 40). RESULTS: The assay showed good discrimination of antibody levels between cases and control sera: seroprevalence of anti-HPV IgG antibodies was significantly higher among vaccinated than unvaccinated girls for both HPV-16 (63.

3% vs. 12.5%; p < 0.001) and HPV-18 (34.7% vs. 20.0%; p = 0.

042), respectively. Thirty-six months after receiving the third dose of vaccine, significantly higher mean anti-HPV-16 (0.618 vs. 0.145), anti-HPV-18 (0.323 vs. 0.

309), and anti-HPV-6 (1.371 vs. 0.981) antibody levels were measured, compared to unvaccinated girls (all p < 0.05). A correlation between optical density and antibody activity indicated assay sensitivity to increasing levels of antibody activity.
