Quadrivalent Seasonal Influenza Vaccine Expands in China

Clover Biopharmaceuticals, Ltd. today announced that it had established a commercial partnership with Keyuan Xinhai Medical Products Trading Co. Ltd. as it prepares for the commercial launch of AdimFlu-S (QIS), the only imported quadrivalent seasonal influenza vaccine approved for use in individuals aged three years and older in China.

“We are thrilled to partner with Kyuan Trade, which has a large and talented commercial team, a broad distribution network that extends across 31 provinces, municipalities, and autonomous regions, and an excellent modern logistics network,” said Joshua Liang, Chief Executive Officer, and Executive Director of Clover, in a press release on May 23, 2023.

Clover expects to launch AdimFlu-S (QIS) later in 2023.

China's seasonal influenza vaccine market has been growing by approximately 30% annually.

Moreover, demand in China continues to shift from trivalent to quadrivalent seasonal influenza vaccine options, which accounted for the majority of doses (70%) in 20222.
