Immune sera from volunteers vaccinated in a blinded Phase 3 clinical trial with JE-VAX ® and a new Japanese encephalitis virus (JEV) vaccine (IC51 or IXIARO), were tested for the ability to protect mice against lethal JEV challenge. Sera from IXIARO vaccinated subjects were pooled into four batches based on neutralizing antibody measured by plaque reduction neutralization test (PRNT 50 titer): high (∼200), medium (∼40–50), low (∼20) and negative (<10). Pooled sera from JE-VAX ® vaccinated subjects (PRNT 50 titer ∼ 55) and pooled JEV antibody negative pre-vaccination sera were used as controls. Groups of ten 6- to 7-week-old female ICR mice were injected intraperitoneally with 0.5 ml of each serum pool diluted 1:2 or 1:10, challenged approximately 18 h later with a lethal dose of either JEV strain SA14 (genotype III) or strain KE-093 (genotype I) and observed for 21 days. All mice in the non-immune serum groups developed clinical signs consistent with JEV infection or died, whereas high titer sera from both IXIARO and JE-VAX ® sera protected 90–100% of the animals. Statistical tests showed similar protection against both JEV strains SA14 and KE-093 and protection correlated with the anti-JEV antibody titer of IXIARO sera as measured by PRNT 50. Ex vivo neutralizing antibody titers showed that almost all mice with a titer of 10 or greater were fully protected. In a separate study, analysis of geometric mean titers (GMTs) of the groups of mice vaccinated with different doses of IXIARO and challenged with JEV SA14 provided additional evidence that titers ≥ 10 were protective.

In China, measles-rubella vaccine and live attenuated SA 14–14–2 Japanese encephalitis vaccine (LJEV) are recommended for simultaneous administration at 8 months of age, which is the youngest recommended age for these vaccines worldwide. We aimed to assess the effect of the co-administration of these vaccines at 8 months of age on the immunogenicity of measles-rubella vaccine. We did a multicentre, open-label, non-inferiority, two-group randomised controlled trial in eight counties or districts in China. We recruited healthy infants aged 8 months who had received all scheduled vaccinations according to the national immunisation recommendations and who lived in the county of the study site. Enrolled infants were randomly assigned (1:1) to receive either measles-rubella vaccine and LJEV simultaneously (measles-rubella plus LJEV group) or measles-rubella vaccine alone (measles-rubella group). The primary outcome was the proportion of infants with IgG antibody seroconversion for measles 6 weeks after vaccination, and a secondary outcome was the proportion of infants with IgG antibody seroconversion for rubella 6 weeks after vaccination. Analyses included all infants who completed the study. We used a 5% margin to establish non-inferiority. This trial was registered at ClinicalTrials.gov (NCT02643433). 1173 infants were assessed for eligibility between Aug 13, 2015, and June 10, 2016. Of 1093 (93%) enrolled infants, 545 were randomly assigned to the measles-rubella plus LJEV group and 548 to the measles-rubella group. Of the infants assigned to each group, 507 in the measles-rubella plus LJEV group and 506 in the measles-rubella group completed the study. Before vaccination, six (1%) of 507 infants in the measles-rubella plus LJEV group and one (<1%) of 506 in the measles-rubella group were seropositive for measles; eight (2%) infants in the measles-rubella plus LJEV group and two (<1%) in the measles-rubella group were seropositive for rubella. 6 weeks after vaccination, measles seroconversion in the measles-rubella plus LJEV group (496 [98%] of 507) was non-inferior to that in the measles-rubella group (499 [99%] of 506; difference −0·8% [90% CI −2·6 to 1·1]) and rubella seroconversion in the measles-rubella plus LJEV group (478 [94%] of 507) was non-inferior to that in the measles-rubella group (473 [94%] of 506 infants; difference 0·8% [90% CI −1·8 to 3·4]). There were no serious adverse events in either group and no evidence of a difference between the two groups in the prevalence of any local adverse event (redness, rashes, and pain) or systemic adverse event (fever, allergy, respiratory infections, diarrhoea, and vomiting). Fever was the most common adverse event (97 [19%] of 507 infants in the measles-rubella plus LJEV group; 108 [21%] of 506 infants in the measles-rubella group). The evidence of similar seroconversion and safety with co-administered LJEV and measles-rubella vaccines supports the co-administration of these vaccines to infants aged 8 months. These results will be important for measles and rubella elimination and the expansion of Japanese encephalitis vaccination in countries where it is endemic.

\"Making sense of Japanese is the fruit of one foolhardy American's thirty-year struggle to learn and teach the Language of the Infinite. Previously known as Gone fishin', this book has brought Jay Rubin more feedback than any of his literary translations or scholarly tomes, \"even if,\" he says, \"you discount the hate mail from spin-casters and the stray gill-netter.\" To convey his conviction that \"the Japanese language is not vague,\" Rubin has dared to explain how some of the most challenging Japanese grammatical forms work ...\" --Publisher description.

The roots of Japan's aggressive, expansionist foreign policy have often been traced to its concern over acute economic vulnerability. Historian Michael Barnhart tests this assumption by examining the events leading up to World War II in the context of Japan's quest for economic security. Drawing on a wide array of Japanese and American sources, this is the first English-language book on the war's origins to be based on research in archives on both sides of the Pacific. Barnhart focuses on the critical years from 1938 to 1941 as he investigates the development of Japan's drive for national economic self-sufficiency and independence and the way in which this drive shaped its internal and external policies. He also explores American economic pressure on Tokyo and assesses its impact on Japan's foreign policy and domestic economy. He concludes that Japan's internal political dynamics, especially the bitter rivalry between its army and navy, played a far greater role in propelling the nation into war with the United States than did its economic condition or even pressure from Washington. Japan Prepares for Total War sheds new light on prewar Japan and confirms the opinions of those in Washington who advocated economic pressure against Japan. At a time of growing interest in U.S.-Japanese economic relations, this book will be stimulating and provocative reading for scholars and students of international relations and American and Asian history.

Background. Japanese encephalitis (JE) is the most important mosquito-borne viral encephalitis and has a high case fatality rate. It is caused by Japanese encephalitis virus. Improved vaccines are urgently needed for residents in countries of endemicity, travelers, and the military. The aim of the present trial was to evaluate the safety and tolerability of IC51, Intercell's Vero cell-derived, purified, inactivated JE vaccine. Methods. This was a randomized (3:1), double-blind, placebo-controlled, multicenter phase 3 trial. Healthy subjects were randomized to receive 2 doses of IC51 (n=2012) or placebo (n=663) at a 4-week interval. Adverse events following immunization (AEFI) were documented over a period of 2 months. Results. The rate of severe AEFI was similar in the IC51 group (0.5%) and the placebo group (0.9%). The rate of medically attended AEFI and all AEFI was also similar in the IC51 group and the placebo group. The same applied for all adverse events, including local and systemic tolerability. Importantly, there were no signs of acute allergic reactions. Conclusion. The Intercell JE vaccine IC51 had a safety profile similar to that of placebo. These data, together with the immunogenicity data from a recent phase 3 trial, form the basis of application for licensure of this vaccine. Trial registration.

Background. Japanese encephalitis (JE) is a vaccine-preventable acute disease. We report the results of a phase 2/3 trial of JENVAC, a Vero cell-derived vaccine developed using an Indian strain of JE virus (JEV). Methods. JENVAC was administered in 2 doses 28 days apart, and immunogenicity was compared to that from a single dose of SA-14-14-2, the only approved JE vaccine and regimen at the time in India. Results. After both the doses, seroconversion and seroprotection were >90% for JENVAC. For SA-14-14-2, seroconversion and seroprotection were 57.69% and 77.56%, respectively, on day 28 and 39.74% and 60.26%, respectively, on day 56. The geometric mean titers at day 28 and day 56 were 145.04 and 460.53, respectively, for JENVAC and 38.56 and 25.29, respectively, for SA-14-14-2. With a single dose of JENVAC, seroprotection titers lasted at least 12 months in >80% of the subjects. Following receipt of 2 doses, 61.17% of subjects retained seroprotection titers at 24 months, and immunogenicity criteria were higher than that for SA-14-14-2 at 12, 18, and 24 months each. Sera from JENVAC subjects neutralized JEV genotypes I, II, III, and IV equally well. Adverse events were not significantly different between the 2 vaccines. Conclusions. JENVAC elicits long-lasting, broadly protective immunity. Clinical Trials Registration. CTRI/2011/07/001855.
