Scientific Evidence Shows That Antibody Levels Can Indicate Coronavirus Immunity
When Dr. Anthony Fauci spoke recently at a White House briefing about the need for COVID-19 booster shots, buried in his slideshow of charts and data points was a little-noticed scientific paper that offers evidence for a reliable way to predict how much protection a COVID-19 vaccine offers.
The study appeared on a preprint server earlier this month without much fanfare, but many interested in the future of COVID-19 vaccines had been eagerly awaiting the results.
The researchers were looking for markers in vaccinated patients’ blood that would indicate protection against COVID-19, what’s known as “correlates of immunity.” What the team of scientists found were neutralizing antibodies — proteins made by the immune system that are known to disarm the coronavirus.
