Tang Ka-piu, a Hong Kong politician who said he received five shots of Chinese-made COVID-19 vaccines, tested positive for COVID-19 on Aug. 5.
He had previously taken three shots of China’s Sinovac COVID-19 vaccine and very recently participated in a mixed-vaccine study in which he took two additional shots.
