Britain last week became the first country in the world to approve a Covid-19 vaccine that targets both the original and Omicron variants.
The UK medicines regulator, the MHRA, approved the vaccine made by US drug company Moderna as a booster for adults.
The agency's decision was based on clinical trial data that showed the booster triggered “a strong immune response” against both Omicron (BA.1) and the original virus, it said.
