When an individual is infected with the COVID-19–causing virus SARS-CoV-2, the immune system is called into action to produce antibodies and T cells that target viral proteins and clear the infection. It has become clear that the recent Omicron variant of SARS-CoV-2 can unfortunately escape antibody responses even in many people who have been vaccinated against COVID-19; however, new research published in Cell and led by investigators at Massachusetts General Hospital (MGH) indicates that T cell responses are still robust against the variant in most individuals with prior SARS-CoV-2 infection or vaccination, thereby providing protection against severe disease.
Study Identifies Factors That Shape Vaccine Preferences
A study involving hypothetical COVID-19 vaccines suggests that vaccine effectiveness and risk of side effects significantly influence people’s preferences for one vaccine over another, and that differences between vaccines may matter less to those who are vaccine hesitant. Sabrina Stöckli of the University of Bern and the University of Zurich, Switzerland, and colleagues present these findings in the open-access journal PLOS ONE on May 4, 2022.
Genetic Breakthrough Creates New Ear Cells Which Can Cure Age-related Deafness
CHICAGO, Ill. — Thanks to the discovery of a “master gene,” scientists can now create new hearing cells that can overcome age-related deafness. The genetic discovery allows for the production of new inner or outer ear hair cells. Until now, hearing loss due to aging, noise, and certain cancer therapies or antibiotics has been irreversible…
