Researchers from around the globe are focused on a common goal: creating a safe and effective vaccine for COVID-19.
A big part of that will undoubtedly be understanding how the human immune system responds to the virus and how people recover.
“If you only look at the antibody’s response to either the virus itself or the vaccine then after a few months, things don’t look so good,” said Dr. Aileen Marty from Florida International University in Miami.
She says antibodies produced after our first exposure to the virus initially provide some protection but research is showing that for many, especially those who tested positive but were asymptomatic, the protection doesn’t seem to last.
“They develop the antibodies and then a few months down the road, ‘Where are the antibodies?’ It’s as if they’ve never been infected,” Marty said.
Instead, researchers are now taking a close look at the body’s T-helper cells and how they respond.
