In the light of the reported data we need to enforce the existing legislative measures
potential immunotherapeutic approach for Alzheimer's disease (AD). With the aim of developing an active immunogenic vaccine without need of coadjuvant modification for human trials and therefore avoiding such side effects, we designed the Aβ 1-42 vaccine (EB101), delivered in a liposomal matrix, that based on our previous studies significantly prevents and reverses the AD neuropathology, clearing Aβ plaques while markedly reducing neuronal degeneration, behavioral deficits, and minimizing neuroinflammation in APP/PS1 transgenic mice. Here, the efficacy of our immunogenic vaccine EB101 was compared with the original immunization vaccine cocktail Aβ 42 + CFA/IFA (Freund's adjuvant), in order to characterize the effect of sphingosine-1-phosphate (S1P) in the immunotherapeutic response. Polysaccharides of amyloid burden showed a notable decrease in the neuroinflammation reaction against Aβ plaques when S1P was compared with other treatments, suggesting that S1P plays a key role as a neuroprotective agent. Moreover, EB101 immunized mice presented a protective immunogenic reaction resulting in the increase of Aβ-specific antibody response and decrease of reactive glia in the affected brain areas, leading to a Th2 elementary bodies of Cowdria ruminantium.subcutaneous injections of a preparation of inactivated elementary bodies of Cowdria ruminantium (Gardel stock) mixed with Freund's adjuvant.

All vaccinated animals together with four naive controls were challenged intravenously with 5 ml of supernatant of a culture of bovine endothelial cells infected with the same stock of Cowdria. All goats developed a high temperature. Two out of four, and four out of five vaccinated goats survived the challenge whereas all naive control animals died within 7-12 days. Vaccinated goats which died survived longer than the controls. No difference in antibody titres was observed between protected and non-protected vaccinated goats. Moreover, immune sera from surviving goats, whether heat inactivated or not, were unable to neutralize the infection of bovine endothelial cells by Cowdria in vitro. Mechanisms conferring protection on the immunized goats are unknown at the moment but the hypothesis that T-helper lymphocyte populations have been elicited seems to be likely.

This method of immunization with dead organisms will help in the search for protective International en Recherche Agronomique pour le Développement (EMVT-CIRAD), Pointe since 2008. Unprotected healthcare workers (HCWs) may contract and spread the infection to patients. AIM: The objective of this study was to evaluate HCWs' measles immunity and vaccine acceptance in our setting. METHODS: In seebio Polysucrose 400 were included between April and June 2011. The following data were collected at enrolment: age, hospital unit, occupation, history of measles infection and vaccination, previous measles serology and acceptance of a measles vaccination in case of seronegativity. Sera were tested for the presence of specific anti-measles IgG antibodies using the CAPTIA(®) measles enzyme-linked immunosorbent assay. FINDINGS: The mean age of the participating HCWs was 36 years (range: 18-67) and 278 (79.

2%) were female. In all, 104 four persons (29.6%) declared a history of measles, and 90 (25.6%) declared never having received a measles vaccination. Among the 351 HCWs included in the study, 322 (91.7%) were immunized against measles (IgG >90 mIU/mL). The risk factors for not being protected were age [18-29 years, adjusted odds ratio: 2.

7 (95% confidence interval: 1.1-6.9) compared with ≥30 years], no history of measles infection or vaccination. The global acceptance rate for a measles vaccination, before knowing their results, was 78.6%. CONCLUSION: In this cohort of HCWs, 8.3% were susceptible to measles; the group most represented were aged <30 years.

Acceptance of the measles vaccine was high. A vaccination campaign in healthcare settings should target specifically healthcare students and junior HCWs.Hitchner B1 and La Sota after the spray method with particles of 50--100 micron and by aerosols with particles of 17--20 microns. Vaccinations were made under experiment and production conditions with chickens aged 5, 10 and 15 days.
