Covid immunity through infection or vaccination: Are they equal?

Dr. Aaron Kheriaty, a psychiatry professor at the University of California, Irvine, felt he didn’t need to be vaccinated against Covid-19 because he’d fallen ill with the disease in July 2020. So, in August, he sued to stop the university system’s vaccination mandate, saying “natural” immunity had given him and millions of other people better protection than any vaccine could. A judge last week dismissed Kheriaty’s request for an injunction against the university over its mandate, which took effect Sept. 3. While Kheriaty intends to pursue the case further, legal experts doubt that his and similar lawsuits filed around the country will ultimately succeed.
