WASHINGTON : In view of the spike in COVID-19 infections globally, a recent study shed light on the strength, durability and breadth of neutralizing antibody responses generated by breakthrough infections in individuals vaccinated against SARS-CoV-2.

The findings were published in 'Cell', one of the scientific journals of Cell Press. Alexandra Walls and David Veesler in the Department of Biochemistry at the University of Washington in Seattle led the project.

Characteristics of the Delta and Omicron coronavirus variants of concern included enhanced transmissibility and immune evasion even in non-immunologically naive individuals, compared to the ancestral pandemic coronavirus.

These characteristics, and the waning of immunity from vaccines, have led to breakthrough infections in vaccinated individuals.

Experts leaning towards evolution of a seasonal infection and living with COVID-19
Omicron wave has plateaued in the province, some medical experts say there are signs society may be headed for a stage where we live with a form of COVID-19 on a regular basis.Some infectuous disease specialists have speculated the Omicron variant could shift COVID-19 from “pandemic” to “endemic,” meaning the circulating virus no longer has the steep waves of outbreaks that hammer hospital capacity and force society to adapt.Thomas Tenkate, a professor with Ryerson University who specializes in health and safety, says he interprets messaging last week from Premier Doug Ford and the province’s chief medical officer as saying “we’re not ever going to get rid of COVID.” Omicron and living with COVID: Why the new variant might change the timeline “So we have to work out how do we manage that in a way that ensures the health care system isn’t overwhelmed,” Tenkate told 900 CHML’s Hamilton Today.“Those measures are very similar to the measures that we’ve been using already.”He says the acceptance of being in an endemic stage revolves around a “thought process and control options” similarly used for seasonal flu and other respiratory viruses.“I suppose they’re using that term, ‘learn to live with it,’ because it’s sort of saying it’s not going to go away,” said Tenkate.Niagara Region’s acting medical officer says although the vaccines are protecting Ontarians and some of the world, there are no indications that population immunity from COVID will be achieved.“Even if we do get that endemic state, immunity is going to wane over time and we’re going to lose that equilibrium,” Dr.
