Alex Sigal

Alex Sigal Alex Sigal is a South Africa–based virologist at the Africa Health Research Institute in Durban, South Africa, the University of KwaZulu-Natal in Durban, and the Hebrew University of Jerusalem. His work concentrates on emerging viruses. His laboratory was the first to isolate the live Omicron BA sub variant and the live Beta variant of SARS-CoV-2 first detected in South Africa. Sigal’s laboratory was also the first to report results on the ability of the Omicron variant to escape antibody neutralization in individuals who had two doses of the Pfizer BNT162b2 vaccine as well as from previous infections, with results also suggesting that vaccination combined with a booster or previous infection can offer protection from symptomatic infection with Omicron.
