Is Penn State accepting serology test results for antibody levels as evidence of immunity from COVID-19?

No. At this time, the science behind the presence of antibodies and level of protection against COVID-19 is still uncertain. Based on the advice of infectious disease experts at Penn State and guidance from the U.S. Food and Drug Administration (FDA), the University is not accepting serology (antibody) tests in lieu of vaccine evidence or for exempting individuals from testing protocols this fall.
