From our labs and clinics: The top 10 COVID-19 science stories of 2021
As COVID-19 waxed, waned, morphed, and waxed again this year, research was taking place throughout Boston Children’s Hospital. Ongoing national studies the hospital is leading or co-leading include Overcoming COVID-19, a CDC-funded study on COVID-19 and multisystem inflammatory syndrome in children (MIS-C); IMPACC, examining immune responses in people hospitalized with COVID-19; and MUSIC, studying MISC’s ...

Emerging protein-based COVID-19 vaccines could be game-changing
Current messenger RNA vaccines appear to offer at least some protection against new SARS-CoV-2 variants, including Omicron, especially for people who have received boosters. But manufacturing costs and the need for ultra-cold refrigeration have limited availability of these vaccines in low-and middle-income countries. That’s where emerging protein-based COVID-19 vaccines — including two candidates developed at ... Read More
