Omicron: evidence shows it evades immunity from earlier infection more than other variants . BENGALURU (REUTERS) - Research by South African scientists suggests that Omicron infection enhances neutralising immunity against the Delta variant of the coronavirus. The immune system does not recognise the virus as efficiently because its mutations have changed its appearance. The Omicron COVID-19 variant is now the dominant strain in the US, outcompeting Delta. Delta shared 92.21% while Omicron shared 80.40% of IEDB . The study, which has not been peer-reviewed, examined. The results of the study are consistent with Omicron displacing the Delta variant, "since it can elicit immunity which neutralises Delta making re-infection with Delta less likely. The scientists found that immunity against a further exposure to omicron rose 14-fold about two weeks after infection, while also discovering that immunity against delta improved 4.4-fold. While Delta infection can lead to serious lung disease, Omicron infection has been found to cause less severe. South African scientists at the Africa Health Research Institute in Durban examined 33 unvaccinated and vaccinated individuals who had contracted the Omicron variant, Reuters reporte Why Covid immunity for past variant won't necessarily protect from new strain The variant has become a major variant of concern, and is spreading widely in the UK.
