news Hong Kong vaccines: information overload, lack of context provoking ‘unnecessary’ fears of Sinovac jabs, experts say A health care worker prepares a dose of China's Sinovac Covid-19 vaccine. Photo: Reuters Hongkongers' fears over the safety of Sinovac Covid-19 vaccines - exacerbated by recent medical emergencies involving people who received the shots - are an "unnecessary" side effect of broad reporting guidelines and a failure by authorities to put the events in the proper context, health experts have said. The city has experienced an apparent plunge in public confidence in the Chinese-made Sinovac vaccine since the first death of a recent recipient of the jab was revealed last week. Reports of two more deaths and three other people requiring intensive care after receiving the shots surfaced in the past week.
