Hong Kong, Macau Suspend Pfizer Vaccine Over 'Flawed' Vials

"For the sake of precaution, the current vaccination must be suspended during the period of investigation," Hong Kong's government said in a statement.

Hong Kong and Macau on Wednesday said they were suspending the use of Pfizer/BioNTech's coronavirus vaccine after being informed of a packaging problem with a batch of vials. "For the sake of precaution, the current vaccination must be suspended during the period of investigation," Hong Kong's government said in a statement. Both Chinese cities said their decision came after they were contacted about the issue by Fosun, the Chinese pharmaceutical company that is distributing the Pfizer/BioNTech vaccine in China. Vials with the lot number 210102 were found to have defective packaging, authorities said.
