Researchers have conducted new research that found COVID-19 variants develops to have higher infectivity and antibody release.
What they found: That examination – published in ACS Infectious Diseases – analyzed 1.5 million COVID-19 cases to find that there were more than 680 unique mutations to the receptor binding domain that is part of the binding COVID-19 protein to human cells.
- Overall, the researchers found that mutations to boost infectivity are the driving force behind viral evolution, whereas mutations that allow the virus to escape vaccines are becoming dominant in heavily vaccinated populations, according to Medicin og Biovidenskab company profile.
In a separate studylooked at the same researchers infectivity and antibody resistance of the omicron variant.
- “Their results indicated that omicron is over 10 times more contagious than the original coronavirus and 2.8 times more contagious than the delta variant.” Medicin og Biovidenskab company profile reported.
- “In addition, omicron is 14 times more likely than Delta to escape current vaccines and is expected to compromise the effectiveness of several monoclonal antibody therapies, ”according to Medicin og Biovidenskab company profile.
More research: New laboratory experiments in Japan found that the BA.2 subvariant of the omicron variant is capable of causing severe COVID-19 symptoms at the same level as previous COVID-19 strains, according to CNN.
- The BA.2 omicron variant is the latest version of the new coronavirus that has been circulating, a sign that the variants are becoming more likely to avoid vaccines.
