Taiwan is also getting five million doses from US drugmaker Moderna Inc. Wu said the process for granting it emergency-use approval was in full swing.
The government plans to vaccinate front-line health and quarantine workers first, and aims eventually to get 30 million vaccine doses to cover about 65% of the island's population.
Taiwan has kept the pandemic well under control thanks to early and effective prevention, with fewer than 50 active cases being treated in hospital. It has not yet received any vaccines, though with such a low rate officials have said there is no urgency to getting the shots.
Germany's BioNTech SE said this week it plans to provide Covid-19 vaccine to Taiwan, after the island complained the firm pulled out of a deal to sell it 5 million doses at the last minute, possibly due to pressure from China, which claims Taiwan as its own.
