The city of 7.5 million people has bought enough doses of the Pfizer/BioNTech vaccine and China’s Sinovac, to vaccinate its entire population, but so far only 2.1 million have been administered since the vaccination programme launched in late February. Thomas Tsang, a former controller of the Centre for Health Protection and member of the government’s vaccine taskforce warned there was only a three-month window to use the first batch of Pfizer/BioNTech vaccines on hand in the city, which must be stored at low temperatures and used within six months... Observers have blamed factors including community mistrust in the Hong Kong and Chinese governments, disinformation and misinformation and a lack of urgency from authorities. In March the BioNtech rollout was suspended for about 10 days after the discovery of damaged packaging of vials which had been administered to more than 150,000 people. Health officials said there was no safety risk but the rollout was suspended as a precautionary measure.
