Sera from patients with nasopharyngeal carcinoma (NPC) show high titres of IgA antibodies to Epstein-Barr viral capsid antigen (IgA/VCA). We reported previously that the serum titres for Epstein-Barr virus-related nuclear antigen-2 (EBNA2) correlated with NPC patients' prognosis. To investigate which is better for diagnosing NPC and predicting patient prognosis, the titration of serum IgA/VCA or EBNA2, we examined the same serum titres. Sixteen cases of NPC in which serum EBNA2 antibody titres had been tested, were investigated for the serum IgA/VCA antibody titres before and after radiation treatment. All NPC cases showed positive reactions with indirect immunofluorescence staining, and the median titre was 252. Twelve normal controls, 5 mesopharyngeal carcinoma patients, 4 hypopharyngeal carcinoma patients, 4 laryngeal carcinoma patients and 6 malignant lymphoma were also examined, but they showed negative or relatively low titres. A follow-up study revealed that IgA/VCA titres remained mostly stable. These results indicate a close relationship between IgA/VCA and NPC, however, prognosis correlated better with EBNA2 titres than with IgA/VCA titres.

Background: Japanese encephalitis virus (JEV) is a leading cause of viral encephalitis in Asia, with high case-fatality rate and morbidity. Although the live recombinant Japanese encephalitis chimeric vaccine (Imojev®) offers strong initial immunity, data on long-term efficacy beyond five years remain limited.
Methods: We conducted a cross-sectional study on adults vaccinated with Imojev® at a specialist travel clinic in Brisbane, Australia.

Musicogenic epilepsy (ME) is characterized by seizures triggered by music. The epileptogenic focus in this rare reflex epilepsy is often in the temporal lobe, although the precise localization is still unclear. A correlation between ME and the presence of GAD65 antibodies indicates a potential immunological pathogenic mechanism.

The first two vaccines administered in the COVID-19 vaccination campaign of India were Covaxin (BBV152) and Covishield (ChAdOx1-nCoV-19). In this study, we evaluate the longevity and sustainability of the humoral immune response after vaccination and various factors influencing it. An observational study was conducted in individuals who received both doses of Covaxin or Covishield vaccine, and their blood samples were analyzed for total-antiRBD-SARS-CoV-2 antibodies.

Purpose: Outer membrane vesicles (OMVs) derived from Gram-negative bacteria naturally serve as a heterologous nano-engineering platform, functioning as effective multi-use nanovesicles for diagnostics, vaccines, and treatments against pathogens. To apply refined OMVs for human theranostic applications, we developed naturally exposed receptor-binding domain (RBD) OMVs grafted with antigen 43 as a minimal modular system targeting angiotensin-converting enzyme 2 (ACE2).
Methods: We constructed -derived OMVs using the antigen 43 autotransporter system to display RBD referred to as viral mimetic Ag43β700_RBD OMVs.

Introduction: Animal influenza viruses pose a danger to the general public. Eurasian avian-like H1N1 (EA H1N1) viruses have recently infected humans in several different countries and are often found in pigs in China, indicating that they have the potential to cause a pandemic. Therefore, there is an urgent need to develop a potent vaccine against EA H1N1.
