Hong Kong’s restaurants and bars may lose up to a quarter of their business this week and the local economy may suffer as well, industry leaders have warned, as nearly half of residents have yet to meet a new vaccination rule set to take effect on Tuesday.

Only slightly more than half of the city’s population has received a third dose of Covid-19 vaccine. Under the next stage of the vaccine pass, residents aged 12 and above must have received three shots or taken their second jab within six months in order to enter most premises, while people who have recovered from Covid-19 for more than six months and were never vaccinated before have to be inoculated with one dose.

About 667,000 people have received the third dose in May so far, with a record high 51,366 getting them on Monday alone, but civil service chief Patrick Nip Tak-kuen on Sunday said about 600,000 who were eligible had not yet received the booster.
