COVID-19 Pandemic Allowed Scientists Opportunity To Observe Human Immune System Responses In Real Time

STAT (3/28, Branswell, Subscription Publication) reports, “The Covid pandemic marked the first time people armed with powerful scientific tools could study how the immune system awakens to and develops defenses against a new threat, in real time, in the global population.” As a result of the pandemic, “scientists have been able to chart how immune systems respond to a single infection, a first dose of Covid vaccine in a naive person, a first infection in a previously vaccinated person, and a first vaccination in a previously infected person – seeing clearly what each encounter activated and how those responses broadened and built on each other.”
