Omicron is displacing delta insights

Omicron infection also produced immunity against Delta. This means someone who has been infected with delta is largely immune to subsequent delta infection. Therefore delta will soon have no one to infect, therefore will go away.

Omicron has been shown to be highly transmissible

Omicron has extensive evasion of neutralizing antibody immunity,

elicited by vaccination and previous SARS-CoV-2 infection.

Omicron infections are rapidly expanding worldwide often in the face of high levels of Delta infections.

Question

Do omicron antibodies neutralise delta virus variant?

Does neutralizing immunity elicited by Omicron also enhances neutralizing immunity against the Delta variant?
