Omicron COVID-19 variant gives little immunity boost to those infected: researchers

Researchers revealed within the British Medical Journal (BMJ) have discovered an infection or vaccination with the omicron variant of COVID-19 do little or nothing to guard in opposition to future infections.

In response to the research’s findings, well being care employees who had been contaminated with the alpha variant of COVID-19 produced a much less highly effective antibody response to the omicron variant.

“The analysis workforce analyzed blood samples from 731 U.Ok. well being care employees who acquired three doses of mRNA vaccine and had completely different SARS-CoV-2 an infection histories, to analyze antibody, T cell, and B cell immunity in opposition to omicron,” the BMJ reported.

The workforce’s analysis confirmed that an infection or vaccination doesn’t present enough safety in opposition to contracting the illness sooner or later.

“Getting contaminated with omicron doesn’t present a potent enhance to immunity in opposition to reinfection with omicron sooner or later. Earlier SARS-CoV-2 an infection impacts on the flexibility to spice up immunity in opposition to subsequent SARS-CoV-2 an infection by means of a course of referred to as ‘immune imprinting,’ and this may increasingly apply to subvariants of omicron together with BA.4 and BA.5,” stated lead creator Rosemary Boyton.
