The World Health Organisation says that the mRNA-based COVID-19 vaccine produced at the WHO-backed vaccine hub in South Africa could take up to three years to get approval if companies do not share their technology and data. Martin Friede, coordinator of the WHO Initiative for Vaccine Research, told Reuters that if companies with approved COVID vaccines or late-stage clinical data shared their technology and data with the consortium, the vaccine produced in South Africa could be approved in 12 to 18 months.
