The International AIDS Vaccine Initiative has established a consortium to elucidate mechanisms of protection conferred by live attenuated simian immunodeficiency virus vaccines in monkeys. Here, the strategies defining key components of the protective immune response elicited by these vaccines are discussed.

Patients with inflammatory bowel disease who receive immunosuppressive therapy have an increased risk of infection. Live vaccines are contraindicated in these patients because of the increased risk of unchecked replication of the attenuated vaccine microorganisms. Vedolizumab is a gut-selective biological agent with a low risk of infection approved for the treatment of inflammatory bowel disease.

Monkeypox virus (MPXV) is an important zoonotic pathogenic virus, which poses serious threats to public health. MPXV infection can be prevented by immunization against the variola virus. Because of the safety risks and side effects of vaccination with live vaccinia virus (VACV) strain Tian Tan (VTT), we constructed two gene-deleted VTT recombinants (TTVAC7 and TTVC5).

Porcine epidemic diarrhea virus (PEDV) has caused significant harm to the global pig industry since its discovery. In this study, a highly pathogenic strain of GIIa PEDV CH/HBXT/2018, isolated previously, was continuously passaged in Vero cells up to passage (P)240, resulting in a completely attenuated virus. The proliferation characteristics of different passages of the strain in Vero cells, pathogenicity in newborn piglets, and mutations in S gene sequence indicated that as the passage number increased, the replication efficiency of PEDV in Vero cells gradually improved, with a more pronounced cytopathic effect.

Background: Marek's disease (MD) is a pathology affecting chickens caused by Marek's disease virus (MDV), an acute transforming alphaherpesvirus of the genus . MD is characterized by paralysis, immune suppression, and the rapid formation of T-cell (primarily CD4+) lymphomas. Over the last 50 years, losses due to MDV infection have been controlled worldwide through vaccination; however, these live-attenuated vaccines are non-sterilizing and potentially contributed to the virulence evolution of MDV field strains.

Background: Prenatal depression is a potentially important fetal exposure as it may alter fetal development and have lasting effects.
Methods: We examined all live births from 2001 to 2012 in British Columbia with follow-up data on the Early Development Instrument (EDI) in Kindergarten. The odds of developmental vulnerability on EDI domains among those with and without depression during pregnancy were estimated.
