Viruses like SARS-CoV-2 use sugar molecules to hide from the immune system, but scientists at Scripps Research have designed a universal coronavirus vaccine that strips these sugars and exposes a stable, rarely mutating part of the spike protein. This approach triggered strong immune responses in
It depends! Sometimes it’s autoimmune, sometimes it’s lingering virus, sometimes it’s disrupted regulatory systems, etc. When it’s the immune system or lingering virus, a new vaccine can often get the immune system to relearn how to correctly handle the virus
