South China Morning Post Blood cancer patient David Allardice was relieved to get his first dose of Covid-19 vaccine two weeks ago, putting him a step closer towards protection against the deadly respiratory disease. But relief turned to shock when it emerged the 55-year-old Hong Kong resident had gone to the wrong vaccination centre – and was given the China-made Sinovac jab rather than the BioNTech one from Germany he actually booked. The mix-up only came to light after the government sent him a text message saying he did not turn up to his vaccine appointment. In fact, Allardice had turned up at the wrong venue, but was waved through without proper checks to be given a dose that he earlier made a deliberate decision not to have after consulting his doctor.
