COVID-19 antibody treatments aren’t as effective on variants. Here’s why – CTV

A new study has found that COVID-19 antibody treatments aren’t as effective for new variants due to the evolving mutations of the differing virus strains.

Authors behind the study, which was published Tuesday in peer-reviewed journal Biochemistry, say the findings could be used to better inform the development of vaccines and therapeutics in the fight against emerging coronavirus variants.

University of Colorado Anschutz Medical Campus professor and corresponding author Krishna Mallela says the study can also aid scientists in understanding the properties of current and new variants.

“Earlier studies, including ours, have focused on explaining the effect of single mutations and not the mechanism underlying the co-evolution of mutations,” Mallela said in a press release.

“Our study helps explain the concept of convergent evolution by balancing positive and negative selection pressures.”
