A further 410,000 doses of Moderna Inc's Covid-19 vaccine will arrive in Taiwan on Wednesday, Deputy Minister of the Interior Chen Tsung-yen said, further boosting the island's efforts to fight a cluster of local infections.

Only around eight per cent of Taiwan's 23.5 million people have received at least one of the two shot regimen against Covid-19, and the government has been under pressure to speed up deliveries of millions of doses it has on order.

“The flight with the 410,000 doses should arrive tomorrow afternoon or early evening if everything is as normal,” Chen told reporters.
