Posts misrepresent approval process for Pfizer's Omicron jab: experts

After the US approved Pfizer-BioNTech's new bivalent vaccine that targets strains of the Omicron variant, Facebook users claimed it was only tested using "preliminary data from eight mice". But experts told AFP this ignores important context, as while the new vaccine was approved after tests on mice, it was based on a previous Omicron jab that underwent clinical trials. They said it was an "established approach" for scientists to use trial data for the previous version of the vaccine in order to approve the bivalent vaccine, similar to the procedure for influenza jabs.
