New York: Moderna has developed a new version of its Covid-19 vaccine which has shown promise against Omicron variant much more than existing shots.
According to the US drug major, the new vaccine targets several mutations abd produced a stronger immune response against the major virus variants, including Omicron and Delta, than the company's current shots, CNBC reported.
The biotech company's redesigned vaccine targets nine mutations found in the Beta Covid variant, as well as the original strain of the virus that first emerged in China's Wuhan in late 2019.
Four of the mutations targeted by the updated vaccine are shared with Omicron.
A 50-microgram dose of Moderna's new vaccine doubled the antibodies, which block the virus from infecting human cells, against the Omicron variant six months after injection compared with the original booster at the same dosage, the data indicated.
The updated shot also increased antibody levels against the Delta variant six months after injection, though they were lower than the response observed with Omicron and did not show superior results in comparison to the original booster, according to the findings posted online, and not peer-reviewed yet.
