SARS-CoV-2 nucleocapsid (N) protein antibodies can be used to identify the serological response to natural infection in those who have previously received a COVID-19 spike-based vaccine. Anti-N antibody responses can also be induced by inactivated whole SARS-CoV-2 virus vaccines, such as CoronaVac. We aimed to characterise antibody responses to the N protein following COVID-19 and following vaccination with CoronaVac.
The nasal epithelium is the primary point of contact for inhaled respiratory viruses such as rhinovirus, respiratory syncytial virus, influenza, and coronavirus, among others. In order to establish infection, these viruses must engage their respective receptors located on host epithelial cells and begin replication.
The airway mucosal epithelium is the main gateway of entry for numerous human respiratory viruses, including human influenza virus, respiratory syncytial virus, coronavirus, and rhinoviruses. For respiratory viruses to perpetuate infection, they must be able to traverse the airway mucosal epithelium and then spread into distal sites of the respiratory tract and lung parenchyma.
Respiratory syncytial virus (RSV) is a leading cause of acute lower respiratory tract infection in young children and the second leading cause of infant death worldwide. While global circulation has been extensively studied for respiratory viruses such as seasonal influenza, and more recently also in great detail for SARS-CoV-2, a lack of global multi-annual sampling of complete RSV genomes limits our understanding of RSV molecular epidemiology.
Males are generally more susceptible to respiratory infections; however, there are few data on the physiological responses to such infections in males and...
Influenza is major cause of paediatric hospitalisation. Influenza vaccine was offered to all children aged 6-59 months resident in Western Australia in 2008
How Influenza outbreaks during mass gatherings have been rarely described, and detailed virologic assessment is lacking.
To assess the immunogenicity and safety of a 2009 influenza A(H1N1) vaccine in children.
The rapid diagnosis of influenza is critical in optimizing clinical management. Rapid antigen tests have decreased sensitivity in detecting pandemic influenza.
