A new form of antibody could counter all known variants of COVID-19, according to a study.
The study was published last Thursday in the Science Advances journal. The research team was led by Duke-NUS Medical School and included scientists from the University of Singapore, the University of Melbourne in Australia and the Fred Hutchinson Cancer Research Center in the United States.
By isolating antibodies from a person vaccinated against COVID-19, researchers determined that the combination of previous coronavirus infection and a vaccine generated potent and “extremely broad” antibodies that could halt the development of the disease. coronavirus.
“This work provides encouraging evidence that pancoronavirus vaccines are possible if they can ‘educate’ the human immune system in the right way,” lead author Wang Linfa said in a press release.
Researchers have identified six antibodies that could neutralize several coronaviruses, including COVID-19, its Alpha, Beta, Gamma, Delta and Omicron variants, the original SARS virus and other coronavirus variants.
“It gives us hope that the creation of a universal coronavirus vaccine is possible,” added Wang Linfa.
