Sharjah24 - Reuters: An Omicron-specific booster could be ready by August, the CEO of U.S. biotech firm Moderna told Reuters, but the firm is still gathering clinical data to determine whether that vaccine would offer better protection than a new dose of the existing jab. Last month Moderna began clinical trials for a booster dose specifically designed to target Omicron but initial results from studies in monkeys show the Omicron-specific shot may not offer stronger protection than a new dose of the existing vaccine.
Moderna chief executive Stephane Bancel said in an interview the company aimed to have a booster ready by August 2022, before next autumn when he said more vulnerable people may need it.
Moderna's vaccines use mRNA technology to provoke an immune response, similar to the shot developed by Pfizer/BioNTech.
"We believe a booster will be needed. I don't know yet if it is going to be the existing vaccine, Omicron-only, or bivalent: Omicron and existing vaccine, two mRNA in one dose."
He said a decision would be made in the coming months when clinical data becomes available.
