The Sinovac vaccine is a Chinese-developed covid vaccine. It was first introduced in 2020 and has since been used by millions of people around the world. Early data suggested that it was about 50% effective, but more recent data has shown that it is actually closer to 80% effective. There is still some debate as to whether or not Sinovac should be used, as it is not as effective as some of the other vaccines available. However, many experts feel that Sinovac is still a valuable tool in the fight against covid.
