TAIPEI, Taiwan (AP) — The sweeping “zero-tolerance” strategy that China has used to keep COVID-19 case numbers low and its economy functioning may, paradoxically, make it harder for the country to exit the pandemic. But the uncompromising approach also means most people in China have never been exposed to the virus. At the same time, the effectiveness of China’s most widely used vaccines has been called into question. Instead, the focus is on developing China’s own mRNA vaccines, like the Pfizer and Moderna formulas. ___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.
