University of Southampton: One third of patients hospitalised with severe COVID-19 still have lung changes after a year

Share A new study has shown that most patients discharged from hospital after experiencing severe COVID-19 infection appear to return to full health, although up to a third do still have evidence of effects upon the lungs one year on. COVID-19 has infected millions of people worldwide. People are most commonly hospitalised for COVID-19 infection when it affects the lungs – termed COVID-19 pneumonia. Whilst significant progress has been made in understanding and treating acute COVID-19 pneumonia, very little is understood about how long it takes for patients to fully recover and whether changes within the lungs persist. In this new study, published in The Lancet Respiratory Medicine, researchers from the University of Southampton worked with collaborators in Wuhan, China, to investigate the natural history of recovery from severe COVID-19 pneumonia up to one year after hospitalisation.

Human challenge models to advance vaccines against respiratory pathogens

Human challenge models to advance vaccines against respiratory pathogens World Immunisation Week 2021 To mark World Immunisation Week 2021 from 24 to 30 April, the London School of Hygiene & Tropical Medicine (LSHTM) Vaccine Centre is hosting a series of webinars. The theme this year is ‘Vaccines Bring Us Closer’. Each day of the week we focus on an important area of vaccine research, science and debate bringing together experts in the field. We end the week with the Vaccine Centre Annual Lecture on 30 April.  In this event, we focus on the use of controlled human infection models to accelerate the development of the next generation of vaccines against bacterial and viral respiratory pathogens, such as pertussis and SARS-CoV-2. Dr Chris Chiu will discuss The COVID-19 human challenge model and Professor Robert Read will explore Advancing the development of improved vaccines against pertussis through a human challenge model .
