Taiwan is administering its domestically developed Covid-19 vaccine, amid criticism that its approval was rushed. The Medigen vaccine had not completed phase three trials when it was granted emergency approval by regulators. Medigen said there were no major safety concerns, and antibodies created were no worse than AstraZeneca's vaccine. It is expected to complete the final round of trials being held in Paraguay later this year. Taiwan's vaccination efforts have been hampered by delivery delays and hesitancy amongst its population. President Tsai Ing-wen led the way in receiving the Medigen jab on 23 August. The objections have mainly come from the opposite political party, the Kuomintang, who say it is unsafe. More than 700,000 people have already signed up for the vaccine, which requires two doses 28 days apart. Less than 5% of Taiwan's population is fully vaccinated: around 40% have received just one dose.
