Shares in China's Shanghai Fosun Pharmaceutical Group fell after Hong Kong and Macau announced on Wednesday that they would suspend vaccinations for BioNTech Covid.
Fosun Pharma, BioNTech's partner in the development and distribution of the Comirnaty Covid-19 vaccine in Greater China, has informed the cities of a packaging error in batch 210102 of the vaccine.
Hong Kong and Macau said they would suspend vaccinations made in Germany as a precaution.
The cities said BioNTech and Fosun Pharma are investigating the cause of the vial cap failure, adding that there is currently no reason to doubt the vaccine's safety.
Macau says all of its messenger RNA or mRNA vaccines belong to the affected batch. Hong Kong said it would also temporarily suspend vaccinations from batch 210104 until the investigation is completed.
Fosun Pharma shares listed in Hong Kong were above 5% on Wednesday afternoon.
Hong Kong approved the BioNTech emergency vaccine in January, while Macau gave the vaccine a special import permit in late February. Both areas received their first shots in late February.
BioNTech's mRNA-based vaccine has a proven efficacy of 95% in adults according to data from its global Phase 3 clinical trial. Real-world data have shown that Pfizer-BioNTech's two-dose Covid vaccine delivers "very strong" results after just one shot.
The news comes as countries around the world struggle to vaccinate their populations amid rising Covid cases in most regions.
So far, Hong Kong has approved vaccines from BioNTech and China's Sinovac. As of Tuesday, the city announced that approximately 403,000 people had received an initial dose, of which 252,800 were Sinovac shots and 150,200 were BioNTech.
More than 124 million infections have been reported worldwide and the death toll from Covid has exceeded 2.7 million, according to Johns Hopkins University.
