Give a choice in vaccine brandBy Wang Fong-yu 王宏育Every year, Taiwan purchases about 7 million doses of influenza vaccines. By the end of the year, about 5 million to 6 million doses would have been used. This year, due to the “immunity debt” factor, a lot of people have recently been coming down with the flu, and there is quite a strong demand for flu vaccines. This year, a flu vaccine marketed by Taiwan’s Medigen Vaccine Biologics Corp has been added to the list. The authorities have only bought 700,000 doses of the Medigen vaccine this year.
