Serological testing for SARS-CoV-2-directed antibodies in 4500 Canadian participants during COVID-19

Key findings from Dr. Pelech's study:
- natural immunity to SARS-CoV-2 was already widespread months before the "pandemic" was announced, particularly in British Columbia
- antibodies against the nucleocapsid protein of the virus are often negative even in persons with a history of the infection
- many conventional antibody tests rely on nucleocapsid antibody detection and therefore are not sensitive, which leads to natural immunity being underestimated
