Hybrid of natural infection with one dose of vaccine superior to vaccine, natural immunity
A combination of natural immunity to COVID-19 (from a previous infection) and vaccine-induced immunity or hybrid immunity offers the best protection against COVID-19, a cohort study done in patients with autoimmune rheumatic diseases (AIRD) in Kochi has reported. In fact, persons who were previously infected with COVID-19 and had a single dose of vaccine afterwards had 30 times higher antibody levels in their blood than those who had received two doses of vaccine but had not had a natural infection, says Padmanabha Shenoy, Kochi-based clinical immunologist and rheumatologist. Dr. Shenoy and his team has been following up a cohort of 1,500 patients with autoimmune rheumatic diseases who have had COVID 19 or were vaccinated to assess their immune response. He derived his conclusions on hybrid immunity after studying the anti-spike antibody levels and neutralising antibody titres in the blood samples of 120 patients from this cohort.More Related News
