I already had COVID-19 and I have proof I have antibodies. Do I still need to get vaccinated?

Antibodies can be a result of a recent infection or vaccine. Even people who recovered from COVID-19 should get vaccinated. Evidence suggests that antibodies from natural infection may not be as robust or long-lasting as those from vaccination and antibodies from a natural infection are not an adequate substitute for vaccination. A recent study in Wisconsin showed that 4 in 10 people who tested positive for COVID-19 last fall no longer had antibodies by spring. Studies also suggest the antibodies produced by vaccination may offer better protection against new variants than those from a natural infection.

Undergraduate students living in campus residence halls are required to test for COVID-19 if UHS does not have proof of vaccination on file. An antibody (or serology) test does not qualify as proof. Students should ensure they submit proof of vaccination to UHS or authorize UHS to access their immunization record.
