AI Article Synopsis

  • * The study focuses on the development of novel nanomaterials and their unique properties, which enhance vaccine effectiveness by influencing antigen availability over time.
  • * Nanoadjuvants offer a promising strategy to improve nasal vaccines, especially for diseases where pathogens enter through mucosal surfaces, and are often central to the intellectual property of new vaccine innovations.

Article Abstract

Vaccines are one of the greatest medical achievements of modern medicine. The nasal mucosa represents an effective route of vaccination for both mucosal immunity and peripheral, being at the same time an inductive and effector site of immunity. In this paper, the innovative and patented compositions and manufacturing procedures of nanomaterials have been studied using the peerreviewed research literature. Nanomaterials have several properties that make them unique as adjuvant for vaccines. Nanoadjuvants through the influence of antigen availability over time affect the immune response. Namely, the amount of antigen reaching the immune system or its release over prolonged periods of time can be effectively increased by nanoadjuvants. Mucosal vaccines are an interesting alternative for immunization of diseases in which pathogens access the body through these epithelia. Nanometric adjuvants are not only a viable approach to improve the efficacy of nasal vaccines but in most of the cases they represent the core of the intellectual property related to the innovative vaccine.

Randomised trial of same vs opposite arm co-administration of inactivated influenza and SARS-CoV-2 mRNA vaccines.

JCI Insight

January 2025

Department of Microbiology and Immunology, Peter Doherty Institute for Infection and Immunity, University of Melbourne, Melbourne, Australia.

Background: The immunogenicity of current influenza vaccines need improvement. Inactivated influenza and COVID-19 mRNA vaccines can be co-administered but randomized controlled trial data is lacking on whether the two vaccines are more immunogenic if given in the same or opposite arms. Murine studies suggest mRNA vaccines can adjuvant influenza vaccines when co-formulated and delivered together.

Enterovirus A71 (EV-A71) has caused hand, foot, and mouth disease with an increased prevalence of neurological complications and acute mortality, threatening young children around the globe. By provoking mucosal immunity, intranasal vaccination has been suggested to prevent EV-A71 infection. However, antigens delivered via the nasal route usually fail to induce a protective memory response.

Background: Understanding protection against SARS-CoV-2 infection by vaccine and hybrid immunity is important for informing public health strategies as new variants emerge.

Methods: We analyzed data from three cohort studies spanning September 1, 2022-July 31, 2023, to estimate COVID-19 vaccine effectiveness (VE) against SARS-CoV-2 infection and symptomatic COVID-19 among adults with and without prior infection in the United States. Participants collected weekly nasal swabs, irrespective of symptoms, annual blood draws, and completed periodic surveys, which included vaccination status and prior infection history.

Article Synopsis
  • Bluetongue virus serotype 3 (BTV-3) was detected in Portugal's Alentejo region in September 2024, first identified in a sheep showing severe symptoms like head swelling and respiratory issues.
  • Two cases were confirmed within the same area, leading to high mortality rates in affected livestock.
  • In light of the rapid spread of BTV-3, monitoring and vaccination campaigns are underway to protect livestock health and control the virus's transmission.
