Why COVID vaccines give way better protection than a COVID infection

“I would advise everyone to get the vaccine,” said Philip Felgner, an infectious disease expert and director of the Vaccine Research and Development Center at the University of California, Irvine. … Felgner and other researchers assessed thousands of blood samples from people who were naturally infected with the coronavirus, versus those who received an FDA-authorized mRNA vaccine …. The new research … found the immune system’s response is “much stronger” with vaccines …. Following the second shot, people had ten times more antibodies than people who recovered from COVID.
