Omicron Variant Might Help Defend Against Delta, Lab Study Suggests
The New York Times
In the lab, antibodies produced during an Omicron infection protected against Delta. If Omicron dominates in the real world, that could lead to a less dire future.
People who have recovered from an infection with the new Omicron coronavirus variant may be able to fend off later infections from the Delta variant, according to a new laboratory study carried out by South African scientists.
If further experiments confirm these findings, they could suggest a less dire future for the pandemic. In the short term, Omicron is expected to create a surge of cases that will put a massive strain on economies and health care systems around the world. But in the longer term, the new research suggests that an Omicron-dominated world might experience fewer hospitalizations and deaths than one in which Delta continues to rage.
“Omicron is likely to push Delta out,” said Alex Sigal, a virologist at the Africa Health Research Institute in Durban, South Africa, who led the new study. “Maybe pushing Delta out is actually a good thing, and we’re looking at something we can live with more easily and that will disrupt us less than the previous variants.”
