In vitro, B.1.617.2 is 6-fold less sensitive to serum neutralising antibodies from recovered individuals, and 8-fold less sensitive to vaccine-elicited antibodies as compared to wild type (WT) Wuhan-1 bearing D614G. […] Additionally we observed that B.1.617.2 had higher replication and spike mediated entry as compared to B.1.617.1, potentially explaining B.1.617.2 dominance.“. Abgerufen am 7. September 2021.

Juli 2021.: „The Delta variant is now in more than 111 countries and we expect it to soon be the dominant COVID-19 strain circulating worldwide, if it isn’t already. The Delta variant is one of the main drivers of the current increase in transmission, fuelled by increased social mixing and mobility, and inconsistent use of proven public health and social measures. At the same time, we continue to see a shocking disparity in the global distribution of vaccines, and unequal access to life-saving tools.“. Abgerufen am 6. September 2021. (en)
