Moderna’s next generation Covid-19 jab could mean that people will only need one annual booster, the pharmaceutical firm has said as it released promising results from trials of its bivalent vaccine, which targets both the original Covid strain and the Omicron variant.
The US firm said early clinical trials on 437 people had shown the jab led to an eight-fold jump in the levels of Omicron-specific “neutralising” antibodies compared to people who had not received a booster.
