Covaxin protects recipients from severe Covid-19: Researchers
According to the researchers, India’s Covaxin activates key memory components of the human immune system that can continue to protect recipients from severe Covid-19 even after the vaccine-generated anti-viral antibodies have waned.
“We see amazingly robust immune memory responses very similar to those caused by the natural infection,” said Nimesh Gupta, a scientist at the National Institute of Immunology (NII), New Delhi, who led the study.
“These memory responses will outlast and confer protection even the concentrations of the initial antibodies deplete over months,” Gupta said.
