Japan’s government may approve using coronavirus vaccines produced by AstraZeneca PLC  and Moderna Inc  as early as May 20, the Nikkei reported on Friday.

Health ministry officials aim to hold a meeting around that date to discuss approval, the financial daily reported.

The only vaccine for the novel coronavirus to have received Japanese approval so far is that developed by Pfizer Inc and BioNTech SE.

Approvals for other vaccines are widely expected to come later this month, though no specific dates have been announced.
