“Dr. Anthony Fauci, the nation’s leading infectious disease expert, said a new study could explain the extraordinary range that people experience with the novel coronavirus, from having no symptoms at all or a mild case to hospitalization or death.
The discovery, which found potential signs of immunity in people who had previously been exposed to other types of coronavirus, could also expand the hunt for a long-lasting COVID-19 vaccine.
Fauci and other scientists said the study published in Science this month held promising findings for understanding why some individuals exposed to COVID-19 for the first time have a modest reaction to the virus.
The study found that the immune systems of roughly half of its subjects appeared to remember past exposure to other, prevalent coronaviruses, including variants of the common cold, equipping them to respond more quickly to a COVID-19 infection once it appeared.”
