Age-specific Responses of Nasal Epithelial Cells to SARS-CoV-2 Infection
Recent research reveals age-specific responses of nasal epithelial cells to SARS-CoV-2 infection, highlighting differences between children and older adults. The study uncovers distinct cell tropism of the virus and varying receptor expression levels across different age groups. Understanding these cellular reactions is crucial in managing COVID-19 cases and developing age-specific treatment strategies.
Annual Two-Dose COVID-19 Vaccination Campaign Could Reduce Hospitalizations and Deaths, Study Suggests
Recent research suggests that an annual two-dose SARS-CoV-2 vaccination campaign could significantly reduce hospitalizations and deaths related to the virus. Administering a second dose of the vaccine five months after the initial dose could result in a substantial decrease in adverse outcomes, according to a study published in the Annals of Internal Medicine. The study emphasizes the potential benefits of adopting an annual vaccination campaign with the provision of a second dose for specific age groups, offering valuable insights for public health officials and policymakers as they continue to combat the ongoing threat of COVID-19.
COVID-19 Virus Found to Persist in Body for Over a Year, UCSF Research Shows
New research from UCSF suggests that COVID-19 virus antigens can persist in the body for over a year after the acute phase of the illness, shedding light on the development of long COVID. The study found evidence of the virus lingering for more than two years in tissue samples, providing valuable insights into the potential impact on the immune system.
