As with rival Moderna (Nasdaq: MRNA), COVID-19 vaccine partners Pfizer (NYSE: PFE) and BioNTech (Nasdaq: BNTX) are keen to show that their adapted booster works better than their original jab against currently-circulating strains.

The partners have presented new data to make the case for using the upgrade to the original Comirnaty jab, which is the world's top-selling COVID-19 vaccine.

These results show that, one month after a 30µg booster dose of the Omicron BA.4/BA.5-adapted bivalent COVID-19 jab, neutralizing antibody titers against emerging Omicron sublineages increased 3.2- to 4.8-fold compared to the companies’ original vaccine.
