Israeli scientists say they have identified antibodies that are so powerful in neutralizing the coronavirus that they could eliminate the need for more vaccine boosters, reports the Times of Israel.
COVID neutralising antibodies
A research team at Tel Aviv University experimented with numerous antibodies and found that two in particular neutralize all known strains of the coronavirus, including Delta and Omicron, in a lab setting.
Antibody infusions are already used to treat some coronavirus patients, and microbiologist Dr. Natalia Freund, who directed the new study, said the antibodies she identified could be used to concoct a particularly potent infusion.
Based on their performance in lab conditions, the antibodies could provide the extra protection that today comes from booster shots, she said, adding that this could potentially make extra shots unnecessary among vaccinated people.
“COVID-19 infection can cause serious illness, and we know that providing antibodies in the first days following infection can stop the spread of the virus,” Freund said.
“It is therefore possible that by using effective antibody treatment, we will not have to provide booster doses to the entire population every time there is a new variant,” she added.
According to Freund, on a technical level, the reason for the success of the two antibodies seems to be that they bind to a different part of the coronavirus spike protein than most others.
Freund’s latest research, newly peer-reviewed and published in Communications Biology, comes from investigations that began in her lab in October 2020.
