  • Based on quantitative Western blot analysis, only two of the 45 (4.4%) Pandemrix-vaccinated narcoleptic patients showed specific antibody response against the NS1 protein from the H1N1pdm09 virus, indicating past infection with the H1N1pdm09 virus. (plos.org)
  • Our vaccine candidate delivers antigens to trigger an immune response via nanoparticles engineered from ferritin--a protein found in almost all living organisms," said Jae Jung, PhD, director of the Global Center for Human Health & Pathogen Research and co-senior author on the study. (eurekalert.org)
  • This protein is an attractive biomaterial for vaccine and drug delivery for many reasons, including that it does not require strict temperature control. (eurekalert.org)
  • The team's vaccine uses the ferritin nanoparticles to deliver tiny, weakened fragments from the region of the SARS-CoV-2 spike protein that selectively binds to the human entry point for the virus (this fragment is called the receptor-binding domain, or RBD). (eurekalert.org)
  • The innate immune system triggers the body's "emergency response" to invaders such as infections. (genengnews.com)
  • Due to the fact that the innate immune system wasn't killing off infected cells, the mice showed an increased viral load and delayed recovery. (genengnews.com)
  • Keenan and Shakespeare are also the first humans, outside of a trial setting, to be given a vaccine that harnesses "mRNA" technology. (livescience.com)
  • It is likely that SARS-CoV-2 will establish as an endemic virus of humans, which has the potential to lead to reverse zoonotic infections in animals that live close to humans. (gla.ac.uk)
  • Recently cat-to-human transmission was reported, demonstrating that a successful cross-species jump of SARS-CoV-2 into cats has the potential to expand the host range of the virus and generate an additional source of infections for humans and other species. (gla.ac.uk)
  • Days before her 91st birthday, Margaret Keenan became the first person in the world to receive the Pfizer-BioNTech COVID-19 vaccine outside of clinical trials. (livescience.com)
  • In 2014, the World Health Organization analyzed epidemiological studies - which included randomized clinical trials, as well as cohort and case control studies - that investigated the effect of the BCG vaccine on all-cause mortality. (cdc.gov)
  • Vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have shown high efficacy, but immunocompromised participants were excluded from controlled clinical trials. (nature.com)
  • Vienna, Austria, November 6, 2017 - Themis today announced positive interim results from an ongoing phase 2 clinical study designed to demonstrate safety and immunogenicity of MV-CHIK, the Company's live attenuated prophylactic vaccine candidate for chikungunya fever. (biospace.com)
  • The clinical program within the Medical Virology Section has 2 main foci: the natural history of viral infections and their intersection with immune defects and early phase therapeutics and vaccines for herpesvirus infections. (nih.gov)
  • In addition, the MVS clinical team collaborates with referring physicians to manage underlying immunodeficiency and/or refractory viral infections. (nih.gov)
  • Higher incidence of BL and NPC seen in developing world demands an effective vaccine to prevent infection and disease onset. (benthamscience.com)
  • The findings suggest the vaccine candidate helped prevent infection and serious disease. (eurekalert.org)
  • The Ixchiq vaccine, developed by Valenva, is approved for adults at increased risk of exposure to the virus. (ghtcoalition.org)
  • Influenza is an infectious viral illness. (cdc.gov)
