Paragraph: Formalin-inactivated Japanese encephalitis virus (JEV) vaccines are widely available, but the effects of formalin inactivation on the antigenic structure of JEV and the profile of antibodies elicited after vaccination are not well understood. We used a panel of monoclonal antibodies (MAbs) to map the antigenic structure of live JEV virus, untreated control virus (UCV), formalin-inactivated commercial vaccine (FICV), and formalin-inactivated virus (FIV). The binding activity of T16 MAb against Nakayama-derived FICV and several strains of FIV was significantly lower compared to live virus and UCV. T16 MAb, a weakly neutralizing JEV serocomplex antibody, was found to inhibit JEV infection at the post-attachment step. The T16 epitope was mapped to amino acids 329, 331, and 389 within domain III (EDIII) of the envelope (E) glycoprotein. When we explored the effect of formalin inactivation on the immunogenicity of JEV, we found that Nakayama-derived FICV, FIV, and UCV all exhibited similar immunogenicity in a mouse model, inducing anti-JEV and anti-EDII 101/ 106/107 epitope-specific antibodies. However, the EDIII 329/331/389 epitope-specific IgG antibody and neutralizing antibody titers were significantly lower for FICV-immunized and FIV-immunized mouse serum than for UCV-immunized. Formalin inactivation seems to alter the antigenic structure of the E protein, which may reduce the potency of commercially available JEV vaccines. Virus inactivation by H 2 O 2 , but not by UV or by short-duration and higher temperature formalin treatment, is able to maintain the antigenic structure of the JEV E protein. Thus, an alternative inactivation method, such as H 2 O 2 , which is able to maintain the integrity of the E protein may be essential to improving the potency of inactivated JEV vaccines. We demonstrated that formalin inactivation of Japanese encephalitis virus (JEV) alters the antigenic structure of the JEV envelope glycoprotein (E), in particular an epitope in domain III, and that this reduces the ability of the inactivated vaccine to elicit protective neutralizing antibodies. Ours and others' previous studies have highlighted the importance of improving the immunogenicity of genotype III (GIII)-derived JEV vaccine in order to provide cross-protection against genotype I (GI) viruses, which are emerging and replacing GIII viruses in many JEV-endemic regions. Encouraging the wide use of live-attenuated or chimeric vaccines, such as SA14-14-2 or yellow-fever 17D/JEV vaccines, respectively, developing GI virus-derived inactivated or premembrane/E-containing, noninfectious virus-like particle (VLP) vaccines are two other possible ways to address this potential problem. In this exploratory study, we highlight an alternative inactivation method, such as H 2 O 2 treatment, which may improve the antigenic stability and immunogenicity of JEV. Japanese encephalitis virus (JEV), the most important etiological agent of viral encephalitis in Asian countries, causes regular outbreaks in eastern and southeastern Asia, India, and more recently in Australia [1,2]. Annually, 30,000 to 50,000 Japanese encephalitis (JE)-confirmed cases are reported in the JEV endemic areas, and 20% to 60% of symptomatic CNS infections are fatal [3-6]; 25% to 50% of symptomatic survivors have long-term neurological sequelae [7] . Asymptomatic JEV infection is about a thousand-fold higher than confirmed cases [8] [9] [10] . JEV is transmitted by virus-infected Culex mosquitos from inapparently infected viremic-amplifying hosts such as pigs or aquatic birds to symptomatic accidental hosts, such as horses and humans. Migratory birds have been implicated as the source of virus been introduced into new geographic regions, and associated with JE epidemics and replacement of genotype III (GIII)with genotype I (GI)-JEV from southeast Asia to east Asia [11, 12] . The genome of JEV consists of a~11-kb, positive-sense, single-stranded RNA, which is translated and processed by viral and host proteases to three structural proteins-capsid, precursor membrane/membrane protein (prM/M) and envelope glycoprotein (E)-and seven nonstructural proteins (NS)-NS1, 2A, 2B, 3, 4A, 4B and 5. The mature virion consists of 180 E proteins forming 90 homodimers and 180 processed M proteins. The immature virion is formed by 60 E and prM hetero-trimers [13, 14] . E protein is the most critical protein eliciting protective immunity in hosts after viral infection, offering critical protection in mice [15] and inducing protective antibodies in recovering humans [16] . The ectodomain of E protein can be separated into three structural domains: E domain I (EDI) to III (EDIII). The fusion peptide in EDII elicits group cross-reactive non-or low-neutralizing antibodies; EDIII, the receptor-binding domain, elicits potent type-specific neutralizing antibodies; and EDI, the center domain connecting EDII and EDIII, elicits complex cross-reactive high-or non-neutralizing antibodies after viral infection [16] [17] [18] . Vaccination remains the most effective strategy to control JE epidemics [19]. Live-attenuated and formalin-inactivated JEV vaccines are available for human use, but only live-attenuated vaccines are available for domestic animals, such as swine and horses. The first generation inactivated JEV vaccine, developed by BIKEN in Japan, was the mouse brain-derived, formalin-inactivated GIII Nakayama strain; manufacture of this vaccine has ceased since 2005 because of undesirable adverse effects [20] .

Paragraph: Background: Chronic Hepatitis B (CHB) remains a major problem for global public health. Viral persistence and immune defects are the two major reasons for CHB, and it was hypothesized that based on a transient clearance of serum viral DNA and HBsAg "window stage", active immunization against hepatitis B virus (HBV) might initiate effective host immune responses versus HBV to achieve functional cure of CHB. Methods: Two experimental mouse models that mice hydrodynamic injected HBV DNA or infected with recombinant AAV/HBV were used. The "sandwich" therapeutic effect by using a potent human anti-HBsAg neutralizing monoclonal antibody (G12) in combination with antiviral drug tenofovir disoproxil fumarate (TDF), followed by active immunization with HBsAg-HBsAb (mYIC) was evaluated. Findings: A single G12 injection rapidly cleared serum HBsAg in HDI-HBV carrier mice, with a synergistic effect in decreasing viral DNA load when TDF was given orally. When both serum viral DNA and HBsAg load became low or undetectable, mYIC was administered. A more effective clearance of viral DNA and HBsAg was observed and serum HBsAb was developed only in these "sandwich"-treated mice. Efficient intrahepatic anti-HBV immune responses were also observed in these mice, including the formation of aggregates of myeloid cells with CD8 + T cells and increased TNF-α, granzyme B production. The "sandwich" combination therapy not only efficiently decreased HBsAg and HBV DNA levels but also induced effective cellular and humoral immunity, which may result in functional cure of CHB. Research in context section Persistence of HBV cccDNA and various host immune defects were shown as the two main obstacles for HBV clearance. Blocking a single target will not be sufficient to achieve functional cure of CHB. A very small percentage of CHB patients could attain "functional cure" by antiviral treatment fol- * Corresponding authors. .cn (Z. Yuan). lowed by interferon therapy. Therapeutic vaccination for CHB showed substantial efficacy. A humanized HBsAb G12 could efficiently block HBV infection and decrease HBsAg level in mice model. This research showed that when both serum viral DNA and HB-sAg load became low or undetectable by antiviral and HBsAb treatment, therapeutic vaccine (mYIC) add on induced effective, host humoral and intrahepatic cellular anti-HBV immune responses, with more rapid and efficient clearance of HBV and HBsAg. Based on optimized antiviral treatment with potent human HB-sAb to rapidly decrease serum HBsAg, followed by boosting host with active immunization provides a novel strategy for functional cure of CHB.

Paragraph: Although promotion of safe hygiene is the single most cost-eff ective means of preventing infectious disease, investment in hygiene is low both in the health and in the water and sanitation sectors. Evidence shows the benefi t of improved hygiene, especially for improved handwashing and safe stool disposal. A growing understanding of what drives hygiene behaviour and creative partnerships are providing fresh approaches to change behaviour. However, some important gaps in our knowledge exist. For example, almost no trials of the eff ectiveness of interventions to improve food hygiene in developing countries are available. We also need to fi gure out how best to make safe hygiene practices matters of daily routine that are sustained by social norms on a mass scale. Full and active involvement of the health sector in getting safe hygiene to all homes, schools, and institutions will bring major gains to public health. Blum D, Feachem RG.
