In addition, scientists claim that these antibodies can also neutralize other variants of Covid-19. By identifying the targets of these “broadly neutralizing” antibodies on the spike protein, it might be possible to design vaccines and antibody treatments that will be effective against not only the omicron variant but other variants that may emerge in the future, said David Veesler, investigator with the Howard Hughes Medical Institute and associate professor of biochemistry at the University of Washington School of Medicine in Seattle.

Likewise, scientists may be able to design vaccines and antibody treatments that would work not just against the Omicron variant but against any mutations that could appear in the future.

The omicron variant has 37 mutations in the spike protein, which it uses to latch onto and invade cells. This is an unusually high number of mutations. It is thought that these changes explain in part why the variant has been able to spread so rapidly, to infect people who have been vaccinated and to reinfect those who have previously been infected.
