Washington, Oct 30 : American biotechnology company Moderna announced that it was preparing for the global launch of its Covid-19 vaccine candidate. "We are actively preparing for the launch of mRNA-1273 and we have signed a number of supply agreements with governments around the world," Xinhua news agency quoted Moderna CEO Stephane Bancel as saying in a statement on Thursday. In addition to the Phase 3 study of the Covid-19 vaccine mRNA-1273, which is fully enrolled, Moderna now has four programs in Phase 2 studies, according to Bancel. "Moderna is committed to the highest data quality standards and rigorous scientific research as we continue to work with regulators to advance mRNA-1273," he said. On October 22, the Phase 3 study of mRNA-1273 completed enrollment of 30,000 participants with approximately 37 per cent of participants from diverse communities. The Phase 1 interim analysis of the vaccine, published in The New England Journal of Medicine on July 14, showed that mRNA-1273 was generally well-tolerated across all age groups and induced rapid and strong immune responses against SARS-CoV-2. /IANS
