China has approved a new Covid-19 vaccine for emergency use, one that was developed by the head of its Centre for Disease Control, adding a fifth shot to its arsenal, AP reported.

Gao Fu, the head of China’s CDC, led the development of a protein subunit vaccine that was approved by regulators last week for emergency use, the Chinese Academy of Sciences’ Institute of Microbiology said in a statement.

It is the fifth coronavirus vaccine approved in China and the fourth to be given emergency use approval. Three of those given emergency approval have since been approved for general use. All were developed by Chinese companies.
