BACKGROUND Pathogenic avian influenza virus (H5N1) has the potential to cause a major global pandemic in humans. Safe and effective vaccines that induce immunologic memory and broad heterotypic response are needed. METHODS AND FINDINGS Healthy adults aged 18-60 and > 60 years (n = 313 and n = 173, respectively) were randomized (1:1) to receive two primary(More)
Although the introduction of tissue culture vaccines for rabies has dramatically improved the immunogenicity and safety of rabies vaccines, they are often prohibitively expensive for developing countries. To examine whether smaller doses of these vaccines could be used, we tested the safety and immunogenicity of purified chick embryo cell vaccine (PCECV) on(More)
Purified chick embryo cell rabies vaccine (PCECV) administered as 0.1 ml intradermally according to the Thai Red Cross (TRC) regimen could reduce the cost of PEP by up to 84% when compared to the traditional five-dose Essen regimen. To confirm the efficacy of 0.1 ml of PCECV using the TRC regimen, a clinical trial was conducted in 113 patients presenting(More)
Currently, two intradermal (ID) regimens for rabies post-exposure prophylaxis (PEP) are recommended by WHO and used in countries where approved by national authorities: the Thai Red Cross (TRC) two-site ID regimen and the eight-site ID regimen. Besides these WHO recommended schedules, a new economical four-site ID regimen was evaluated that reduces the cost(More)
Tick-borne encephalitis (TBE) is caused by an arthropod-borne virus, belonging to the family of Flaviviridae. In case of disease, which can lead to neurological sequelae or even fatal outcomes, only symptomatic treatment is available. TBE can be prevented by vaccination. Various primary immunization schedules have been developed. To identify the most(More)
This study investigated the immune response and safety in 430 adults, when boosted more than 3 years after primary or booster TBE immunisation as measured by neutralization test (NT) and ELISA. Tested by NT, the post-booster day 21 geometric mean titer (GMT) was 331 and 142 for the 18-49 and > or =50 years old, respectively. The post-/pre-booster geometric(More)
Tick-borne encephalitis (TBE) is an important, vaccine-preventable arthropod-borne disease, causing severe illness in children too. In order to evaluate the immune response to different licensed primary immunization schedules, a total of 294 children aged 1 to 11 years of age were enrolled in a randomized, controlled, multi-center trial. The subjects were(More)
Immune responses to vaccination are tested in clinical trials. This process usually requires years especially when immune memory and persistence are analyzed. Markers able to quickly predict the immune response would be very useful, particularly when dealing with emerging diseases that require a rapid response, such as avian influenza. To address this(More)
Proactive priming before the next pandemic could induce immune memory responses to novel influenza antigens. In an open-label study, we analyzed B cell memory and antibody responses of 54 adults who received 2 7.5-microg doses of MF59-adjuvanted A/Vietnam/1194/2004 clade 1 (H5N1) vaccine. Twenty-four subjects had been previously primed with MF59-adjuvanted(More)
n engl j med 359;15 october 9, 2008 1631 clinical stage II disease (primary lesion, >2 cm; node-negative).2 These rates are much lower than the 90% rate cited by Wong et al. Unfortunately, the majority of patients do not fare even this well, since the overall 5-year survival rates range from 30 to 64%.3 In our opinion, this warrants more(More)
