Research: Omicron antibody may be effective for Delta and can play an alternative role

Original title: Research: Omicron antibody may be effective on Delta and can play an alternative role
A study in South Africa has found that Omicron may replace Delta.
According to CNBC, the team led by Khadija Khan, a scientist at the African Institute of health, released the results of a small study this week, saying that patients infected with Omicron virus may enhance their immunity to delta virus.
Novel coronavirus pneumonia incidence rate will be reduced, and the damage to individuals and society will be weakened if they are replaced by delta and prove to be milder than the previous variants.
The team of scientists wrote in their research:
"Omicron virus can trigger immunity and make delta virus lose immunity, so as to reduce the possibility of re infection with delta virus."
The study has not been peer-reviewed. Because of the urgency of the pandemic, researchers published their findings before other experts in the field evaluated it.
The study followed 13 people, 11 of whom were infected with Omicron. Seven of the participants were vaccinated: three were vaccinated with two doses of Pfizer and biontech, and four were vaccinated with Johnson & Johnson.
The antibody response of patients infected with Omicron seems to have increased their immunity to Delta by more than four times after two weeks of participating in the study. Participants also showed a 14 fold increase in the ability of antibodies to block Omicron reinfection.
However, the scientists cautioned that it is unclear whether the enhancement of protective ability is due to Omicron induced antibodies, vaccination or immunity from previous infections. Vaccinated people show greater protection.
According to the U.S. Centers for Disease Control and prevention, among the new cases in the United States last week, Omicron virus infection accounted for 58% and delta accounted for 41%.
