Omicron neutralising antibodies after COVID-19 vaccination in ... "If high levels of neutralising antibodies are elicited to Omicron following infection, then we would expect to see some level of protection against reinfection with Omicron, but this is likely to be short-lived," says Professor Gilda Tachedjian, a virologist at . The Omicron variant is slowly replacing the Delta variant around the world. Another preprint study posted earlier this month found that a previous infection protects against symptomatic reinfection with the Alpha, Beta, or Delta variants by about 90%, but only 30% for the Omicron variant. First, your antibody levels. The antibody titers from Beta-infected subjects were similar to the COVID-19 convalescents who experienced Omicron BA.2 or BA.1 infections. Immunity gained through just two vaccinations or infection with earlier variants of covid-19 (such as delta or alpha) will not necessarily prevent omicron infection, Zur Wiesch says. Recent results showed that there was evidence of significant waning of antibody reactivity against Delta and Omicron six months after the second dose of vaccine.
