US biotech firm Moderna on Monday announced its experimental vaccine against Covid-19 was 94.5 per cent effective, marking a second major breakthrough in the vaccine hunt.
Moderna released early results from a clinical trial with more than 30,000 participants, after US pharmaceutical company Pfizer and its German partner BioNTech last week said their vaccine was 90 per cent effective.
